Mechanical Specifications - Centrifugal Water Chillers Item: A1, A2 Qty: 3 Tag(s): C-1, C-2, C-3 Compressor-Motor Direct drive multiple-stage compressor, multi-stage capacity control guide vanes. Shrouded aluminum alloy impellers dynamically balanced. Motor-compressor assembly balanced to .15 in./sec (.0038m/sec) maximum vibration measured on motor and bearing housings. Refrigerant cooled, hermetically sealed, two-pole, squirrel cage induction motor. Two pressure lubricated bearings support the rotating assembly. A direct drive submerged oil pump motor, 3/4 hp (.560 kW) 115V/50/60/1 provides filtered and temperature controlled oil to compressor bearings. Evaporator-Condenser Shells are carbon steel plate. Evaporator includes rupture disk per BSR/ASHRAE 15 Safety Code. Carbon steel tube sheets are drilled, reamed and grooved to accommodate tubes. Tubes are individually replaceable externally finned seamless copper. Tubes are mechanically expanded into tube sheets. Eliminators are installed over entire length of the evaporator tube bundle. A multiple orifice control system maintains proper refrigerant flow. Condenser baffle prevents direct impingement of compressor discharge gas upon the tubes. Refrigerant side of the assembled unit is tested at both pressure(30.00 psi leak test) and vacuum. Water side is hydrostatically tested at one and one-half times design working pressure, but not less than 225.00 psi. Trane reserves the right to implement chiller technology enhancements that will reduce the chiller's refrigerant charge, with no impact on chiller performance. Changes may be reflected in the chiller's nameplate refrigerant charge and the quantity of refrigerant charge shipped to the jobsite, depending upon the final date of equipment manufacture. Water Boxes Drains and vents - All water boxes have 3/4-inch NPTI vents and drain connections provided. Evaporators have 2 vents and 2 drains, condensers have 1 vent and 1 drain. Non-marine water boxes have water connections that extend out from the end. Economizer A flash economizer with no moving parts provides power saving capability. Purge System The EarthWise(TM) purge includes a 1/4 hp 115V/60/1, 100V/50/1 air cooled condensing unit, purge tank, drier elements, a 1/20 hp (.037 kW) 115V/60/1, 110V/50/1 pump-out compressor, a carbon tank, and a heater. The purge is designed with an activated carbon filtration system that includes an autoregeneration feature which results in automatic high-efficiency removal of noncondensibles from the chiller without manual carbon maintenance. The purge is rated in accordance with ARI Standard 580. Adaptiview Control Panel: The Tracer(tm) Adaptiview is a microprocessor-based chiller control system that provides complete stand alone system control and monitoring for the water cooled CenTraVac (TM). It is a factory mounted package including a full complement of controls to safely and efficiently operate the CenTraVac chiller, including oil management, purge operation, interface to the starter, and comprehensive motor protection including three phase solid state motor overload. Inlet and outlet water (fluid) temperature sensors are located in the evaporator and condenser waterbox connections as standard. The display is a touch sensitive 12 1/8" diagonal color liquid crystal display (LCD) that uses color graphics and animation to ensure ease of use. The touch sensitive interface allows the operator to view the chiller graphically and receive a status indication via subsystem animations. The operator can navigate easily between the primary chiller subsystems including: compressor, evaporator, condenser, and motor. For each subsystem, you can view status and detailed operating parameters. In addition, alarms, reports, trending, and settings can all be accessed quickly from the main screen. The display is mounted on a flexible "arm" that allows extensive height and viewing angle variations. The panel supports an extensive list of Languages including the default English. The data can be set to be viewed in inch pounds IP or metric units SI. For remote starters - Class 1 control panel voltage (30-115 V) are clearly labeled in the control panel. Class 2 input voltage (30V max) is also labeled in the control panel.

Each report is comprised of a detailed listing of operational data relative to that chiller subsystem. Control functions including: *leaving chilled water temperature *percent demand limit *chiller water reset (based on return water temperature *front panel control type *setpoint source *differential to start *differential to stop Status data including: *waiting to start *running *run limit *run inhibit (adaptive) *auto *free cooling (option) *preparing to shutdown *shutting down (post lube) *stopped Safeties including: Automatic safety shutdown for: *Low chilled water temperature, *low evaporator refrigerant temperature *high condenser refrigerant pressure *evaporator and condenser flow status *low evaporator/condenser differential refrigerant pressure *low oil pressure *oil pressure overdue *high or low oil temperature *high bearing oil temperature (requires enhanced protection option) *high motor current *high motor temperature



*starter function faults *critical temperature and pressure sensor faults. The devices are of a latching trip out type requiring manual reset. Non-latching safety trip outs for operating conditions external to the chiller automatically permits unit to resume normal operation when condition is corrected. Advanced motor protection monitors 3-phase current to provide latching trip out protection from adverse effects of phase loss, phase unbalance, phase reversal, loss of phase reversal protection, and electrical distribution faults (momentary power loss) by instantaneous trip out of motor. Surge protection - Detects surge and limits chiller loading through inlet vane modulation. Head relief through lowering cooling tower water temperature can be requested. If not corrected within 7 minutes, chiller is shut down. Enhanced Adaptive Control(TM) - Built in intelligence to keep the chiller on line (safely making maximum tons) while simultaneously preventing chiller damage/failure. During any chiller limiting mode of operation, the control panel enunciates the condition via a relay output. Trending: The controller provides 10 standard graphs for trending multiple parameters The operator can add an additional 6 custom graphs if desired. On any one custom graph, the operator can choose to trend up to 10 unique parameters from a more comprehensive list. Two Y axes are available for any graph to facilitate readability. Diagnostics: Adaptview includes comprehensive diagnostic monitoring. All active diagnostics are available, and up to 20 historic diagnostics are communicated to the operator via the 12 1/8" LCD display with graphic navigation system. Each diagnostic is time and date stamped. Service Tool: A PC-based service tool, connected to the chiller via USB port, is available and displays the last 100 diagnostics, indicating the time, date of occurrence, and system parameters at the time of the diagnostic. The service tool provides advanced troubleshooting and access to sophisticated configuration settings not needed during operation of the chiller. Security: The Adaptview can be set to prevent unauthorized access to the chiller settings. The operator can choose to secure the operating settings with a password. Data and reports can still be accessed once the settings are locked out. The memory for the Adaptiview is non-volatile type, so if power is lost, operating settings are retained. A life time battery is standard, which is used only to support the clock function for the chiller. Chilled and Condenser water pump relays: Chilled water and condenser water pump relays are provided and it is recommended that they be used for pump control. Enhanced Protection Option provides: Bearing temperatures sensors installed for both bearings, displayed on unit controller Compressor discharge refrigerant from the compressor Actual pressure transducer in the condenser for enhanced condenser limit control Operating Status: The following hardwire binary outputs are available: Compressor running relay Alarm relay - manual reset Alarm relay - auto reset Limit warning relay Purge alarm relay Head relief request relay Maximum capacity relay Communications Interface for Chillers Inputs ======== Chiller Enable/Disable Command Chilled Water Setpoint

Isolation All units ship with neoprene isolator pads as standard. Enough pads are provided to cover the area under the chiller supports.



Shipment All units are of hermetic design, leak tested, charged to 5.00 psi and shipped as a single factory assembled package. Full oil charge shipped in oil sump. Refrigerant shipped to jobsite from refrigerant manufacturer. The entire chiller is shrink wrapped for protection. RuptureGuard-Relief Valve-Field Install RuptureGuard is a Trane supplied field installed refrigerant containment system that replaces a chiller's rupture disk. The system consists of a non-fragmenting rupture disk and a pressure relief valve that can be applied to all low pressure centrifugal chillers. The rupture disk functions as the chiller's primary pressure relieving device and provides a leak free seal between the chiller and atmosphere. The pressure relief valve is installed downstream of the rupture disk and functions as an interim primary pressure relieving device and seal. When the chiller's internal pressure exceeds 15 psig[104 kPa], the rupture disk bursts allowing the pressure to be relived through the relief valve. After the chiller's pressure is reduced, the pressure relief valve closes stopping the flow of refrigerant to the atmosphere. A pressure switch is included with the RuptureGuard package as standard. This switch has single pole, double throw contacts for interface to external monitoring systems. The switch has a trip setting of 11 psig , reset values of 8 psig, and is rated for 5A at 220 volts. TRANE Adaptive Frequency Drive (AFD) (C-1 & 2) The Trane AFD is a closed-loop, liquid refrigerant cooled, microprocessor based pulsed width modulation design. The AFD is both voltage and current regulated. Output power devices: IGBT transistors. The AFD is factory mounted on the chiller and ships completely assembled, wired and tested. Patented Trane AFD control logic is specifically designed to interface with the centrifugal water chiller controls. AFD control adapts to the operating ranges and specific characteristics of the chiller, and chiller efficiency is optimized by coordinating compressor motor speed and compressor inlet guide vane position. Chilled water control and AFD control work together to maintain the chilled water setpoint, improve efficiency and avoid surge. If a surge is detected, AFD surge avoidance logic will make adjustments to move away from and avoid surge at similar conditions in the future. Use only copper conductors for terminal connections. Failure to do so may cause corrosion or overheating, and starter damage. AFD Design Features * NEMA 1 ventilated enclosure with a hinged, locking door is tested to a short circuit rating of 65,000 amps. It includes a padlockable door-mounted circuit breaker/shunt trip with AIC rating of 65,000 amps. The entire package is UL/CUL listed. * Simple modular construction. * The drive is rated for 480/60/3 input power, +/-10%. * Displacement power factor of .99 at full load, minimum of .96 at all other part loads. * Minimum efficiency of 97% at rated load and 60 hertz. * Full motor voltage is applied regardless of the input voltage. * Soft-start; linear acceleration; coast to stop. * Adjustable frequency from 38 to 60 hertz. * All control circuit voltages are physically and electrically isolated from power circuit voltage. * 150% instantaneous torque available for improved surge control. * Output line-to-line and line-to-ground short circuit protection. * Harmonic attenuation- integrated active rectification control of the building AC power assures low line-generated harmonics back to the users power grid. The AFD has less than or equal to 5% current total demand distortion (TDD) as measured at the AFD. Chiller Unit Control Features for AFD Chiller Unit Control Features for AFD The chiller unit control panel capabilities provide for the control/configuration interface to, and the retrieval/display of, AFD-related data. AFD standard design features controlled through Adapiview include: * Current limited to 100% * Motor overload protection. * Motor overtemperature protection. * Phase loss, reversal, imbalance protection. * Overvoltage/undervoltage protection. Digitally displayed on the AdaptiView panel: output speed in hertz, output speed in rpm, input line voltage, input line kw, output/load amps, average current in % RLA, load power factor, fault, AFD transistor temperature. Environmental Ratings: * 32F to 104 (0C to 40) operating ambient temperature



* Altitude to 3300 feet (1000m), amperage derate of 1% per every 300 feet above 3300 feet * Humidity, 95% non-condensing Solid State Starter (Unit Mounted) (C-3) Solid State Reduced Voltage, NEMA 1A (vented) enclosure with a gasket. Starter factory mounted and completely prewired to compressor motor and control panel. Factory run testing assures proper circuitry and operational reliability. The solid state starter is a reduced voltage starter and therefore draws ~ 45% of locker rotor amps (LRA), and the motor acceleration time is 3-8 seconds typically. The starter is designed and tested in accordance with UL 508. UL and CUL are standard Features include: Features include: Reduced inrush of amperage during chiller start, approximately 45 % of LRA Starting current is factory set and field adjustable Power section includes (6) silicon controlled rectifiers SCR's Air-cooled design, no liquid cooling circuit required Bypass design allows for SCR use only when necessary i.e. starting and stopping 115 volt control power transformer to power chiller unit controller, purge and oil system. Therefore, with line power, no other power is needed for auxiliary equipment on the chiller. Environmental specification: Operation from sea level to 6000 ft (1829 m). Operating ambient temperature range 32.0 F to 104.0 F. Non-operating ambient temperature range -40.0 F to 158.0 F. Relative humidity, non-condensing 5% to 95% through the ambient temperature range. Voltage utilization ±10 % Top of starter includes access area for convenience in cutting wiring access area. Bottom entry for line power is not available. Terminal block connection is standard. Non-fused disconnects or circuit breakers may be included as an option. See the following submittal pages for disconnect ratings and lug information on these optional disconnects if offered. Circuit breaker is mounted on starter. Starter door cannot be opened unless Circuit breaker is off. Starter installer responsibilities The following are considered functions normally required of the equipment installer for unit mounted starters. Remove access area panel for line side wiring. The top of the starter provides the recommended access to starter/disconnect lugs. The starter can accommodate top line power entry only. Provide and install field wiring to line side lugs of starter. Required Installer Responsibilities The following are considered functions normally required of the equipment installer./n Install unit on a foundation with flat support surfaces level within 1/16" and of sufficient length to support concentrated loading. (Spring isolators should be considered whenever chiller installation is planned for an upper story location.) Place isolation pads or optional spring type isolators provided by the chiller manufacturer under the unit. Install unit per applicable Trane Installation Manual. Install purge (ships separate on heat recovery units only). Complete all water and electrical connections. Where specified, provide and install valves in water piping upstream and downstream of the evaporator and condenser water boxes as means of isolating shells for maintenance and to balance and trim system.



Furnish and install a flow switch with timer or equivalent device in both the chilled water and condenser water piping properly interlocked to insure that unit can operate only when water flow is established. Furnish and install taps for thermometers and pressure gauges in water piping adjacent to inlet and outlet connections of both evaporator and condenser. Furnish and install drain valves to each water box. Install vent cocks on each water box. Where specified, furnish and install strainers ahead of all pumps and automatic modulating valves.. Furnish sufficient refrigerant 25.0 lb per machine and dry nitrogen 50.0 lb per machine for pressure testing under manufacturer's supervision. Start-up unit under supervision of a qualified Trane field engineer. Where specified, insulate evaporator and any other portions of machine required to prevent sweating under normal operating conditions. Water connection piping must not transfer forces to the chiller. Because of cumulative tolerances in manufacture and field installation, prepiping of water connections closer than 36" is not recommended. Any problems associated with prepiping of water connections closer than 36" to the chiller are the responsibility of the installing contractor. Furnish and install vent lines for rupture disk and purge venting to atmosphere per ASHRAE 15 and unit installation manual. If RuptureGuard-Relief Valve option is ordered, remove factory rupture disk and install RuptureGuard-Relief Valve per the IOM manual. Leak-Tight Warranty The CenTraVac chiller features a 5-year leak-tight warranty of no more than 0.5% per year. The warranty covers models CVHE/F and CDHF chillers installed in the United States and Canada. The Companys obligations and liabilities under this warranty are limited to furnishing replacement refrigerant. No liability whatever shall attach to the Company until appropriate actions have been taken to eliminate the source of the leak and then said liability shall be limited to the purchase price of the refrigerant lost in excess of 0.5% per year. After the first five years of ownership, the leak-tight warranty will remain in effect at no additional cost if the CenTraVac chiller has, at all times since its purchase from Trane, been covered by a comprehensive Trane service and maintenance agreement. Any further warranty must be in writing, signed by an officer of the Company.

Warnings, Cautions and Notices

Warnings, Cautions and Notices. Note that warnings, cautions and notices appear at appropriate intervals throughout this manual. Warnings are provide to alert installing contractors to potential hazards that could result in personal injury or death. Cautions are designed to alert personnel to hazardous situations that could result in personal injury, while notices indicate a situation that could result in equipment or property-damage-only accidents.

Your personal safety and the proper operation of this machine depend upon the strict observance of these precautions.

Important

Environmental Concerns!

Scientific research has shown that certain man-made chemicals can affect the earth’s naturally occurring stratospheric ozone layer when released to the atmosphere. In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential impact to the environment. Trane advocates the responsible handling of all refrigerants-including industry replacements for CFCs such as HCFCs and HFCs.

Responsible Refrigerant Practices!

Trane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified. The Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.

� WARNING

Contains Refrigerant!

System contains oil and refrigerant and may be under positive pressure. Recover refrigerant to relieve pressure before opening the system. See unit nameplate for refrigerant type. Do not use non-approved refrigerants, refrigerant substitutes, or refrigerant additives.

Failure to follow proper procedures or the use of non-approved refrigerants, refrigerant substitutes, or refrigerant additives could result in death or serious injury or equipment damage.

ATTENTION: Warnings, Cautions and Notices appear at appropriate sections throughout this literature. Read these carefully.

� WARNING: Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

� CAUTION: Indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury. It could also be used to alert against unsafe practices.

NOTICE: Indicates a situation that could result in equipment or property-damage only accidents.

General Information

The information and procedures in this document are to facilitate unit disassembly for clearance and access reasons during the installation process.

The understanding is that the chiller has what is referred to as the “compressor doweling option” or “separable shell option” (which includes compressor doweling). Compressor doweling sets up the compressor for removal. The separable shell option includes a bolt-together design between the evaporator and condenser and allows the shells to be separated in the field.

Important: These procedures do NOT apply to units that have been installed and electrical supply wiring has been completed.

Contractor Responsibilities

• Handle/lift and rig equipment

• Protect all internal components from exposure to elements, which could contaminate or corrode chiller components.

• Chiller reassembly

• Replace all gaskets with new gaskets or O-rings and sealing compound.1

• Change the compressor oil1

• Evacuate the chiller under 1000 microns1

• Recharge the chiller with dry nitrogen to 5 psig1

• Replace and/or repair insulation

• Reconnect electrical connections

• Spot paint the chiller if necessary

Compressor/Motor Disassembly

Remove Nitrogen Charge

Important: Remove the nitrogen charge from the chiller vessel before starting any disassembly procedures.

Introduction

The disassembly and reassembly procedures described in this manual should be performed only on chillers that have been ordered with this shell option. The process is to be initiated by experienced service technicians. Contact your local Trane Service office for assistance if required.

This section discusses a typical disassembly process. Proper lifting techniques vary based on mechanical room layout.

• It is the responsibility of the person(s) performing the work to be properly trained in the safe practice of rigging, lifting, securing, and fastening the components involved.

• It is the responsibility of the person(s) providing and using the rigging and lifting devices to inspect these devices to ensure they are free from defect and are rated to meet or exceed the published weights.

• Always use rigging and lifting devices in accordance with the applicable instructions for such devices.

� WARNING

Heavy Objects!

Each of the cables (chains or slings) used to lift the unit must be capable of supporting the entire weight of the component. Lifting cables (chains or slings) may not be of the same length. Adjust as necessary for even component lift. Other lifting arrangements may cause equipment or property-only damage. Failure to properly lift component could result in death or serious injury.

Wiring Disassembly

Before separating shells, remove the purge, the compressor, and the various unit mounted sensors (frame LLIDs) as indicated. If possible, the best method is to remove the sensor and carefully coil the wire after labeling the device and its location to aid in reinstallation. All sensors connect to the buss wiring with a universal plug. This allows easy disconnection and reconnection of the sensors.

Purge Unit Removal

� WARNING




18 CVHE-SVN04D-EN


� WARNING

Hazardous Voltage w/Capacitors!

Disconnect all electric power, including remote disconnects and discharge all motor start/run capacitors before servicing. Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized. Verify with an appropriate voltmeter that all capacitors have discharged. Failure to disconnect power and discharge capacitors before servicing could result in death or serious injury.

Note: For additional information regarding the safe discharge of capacitors, see PROD-SVB06A-EN or PROD-SVB06A-FR

To remove the purge assembly from the top of the condenser:

1. Isolate the purge unit from the condenser shell by closing the vapor and liquid line valves.

2. Disconnect and mark all piping and wiring attached to the purge unit. Sand all paint off at points and use a tubing cutter where cuts are to be made. See Figure 5 (below) and Figure 6, p. 19.

3. Remove the fasteners connecting the purge unit base to its mounting bracket.

4. Lift the purge unit clear of the chiller and store in a clean, dry area.

Reassemble the purge unit in reverse order when the process is complete.

CVHE-SVN04D-EN 19


Compressor Motor Assembly Removal

NOTICE

Doweling Must Be Completed Prior to Disassembly!

The compressor motor assembly must not be removed from the chiller unless special doweling has been installed at the factory. Doweling must be installed to prevent the interstage casings from shifting. If the compressor/motor assembly is lifted without doweling installed, the internal alignment may shift. It would then be necessary to disassemble and then reassemble the compressor making sure that all internal clearances and specifications are proper. If the internal components shift and the chiller is started, serious compressor damage could result. If doweling is not factory installed, and it is necessary to install doweling, contact the local Trane Service Company. The compressor discharge flange and mounting foot are also doweled at the factory to provide proper alignment during reassembly.

Figure 7 (below) through Figure 9, p. 20 show factory-installed compressor doweling. If components are not factory doweled, doweling must be installed before proceeding. Contact the local Trane Service Company.

2. Disconnect all external vent lines, motor cooling supply and drain lines, and oil supply and drain lines which are connected to the compressor and compressor motor. Sand all paint off the points where cuts are to be made. Use a tubing cutter to insure that cuts are smooth and square. Figure 13 (below) and Figure 14, p. 23 illustrate these lines. Couplings will be used to reconnect the lines when reassembling the chiller. Cap open lines to prevent entry of foreign material.

Figure 13. Lubrication system supply, drain, and vent lines

CVHE-SVN04D-EN 23


3. Remove the control panel if necessary. Also, disconnect and remove the unit mounted starter, if so equipped. See “Control Panel Removal,” p. 27 for instructions.

4. Remove the economizer vent pipe flange bolts at the compressor connection. See “Economizer Removal,” p. 25 for instructions.

� WARNING

Heavy Objects!


5. Consult with a rigging specialist before removing the compressor assembly. Employ rigging specialist procedures when removing compressor assembly.

There are two styles of suction elbows, a 90° elbow and a three-piece elbow, that can be found in the disassembly process.

� WARNING

Improper Use of Elbow Lifting Tab!

Do not lift chiller using elbow lifting tab. Elbow lifting tab and approved clevis are used ONLY when removing elbow from chiller. Using the elbow lifting tab to lift chiller could result in chiller dropping which could result in death, serious injury, or equipment damage.

6. Remove the suction elbow.

a. Use a sling to support the 90° elbow style suction elbow. Apply slight lifting pressure.

Figure 14. Lubrication system motor cooling lines

24 CVHE-SVN04D-EN


b. Three-piece suction elbows have a lifting tab. You will need a lifting clevis to remove the elbow. A Crosby screw pin shackle, model S-209, stock number 1018482 with a 5/8” pin is acceptable as shown in Figure 15.

c. Remove the bolts from the control mounting bracket on the back of the control panel.

d. Remove the suction elbow bolts at the compressor and evaporator connections.

e. Lift the suction elbow from the chiller being careful to not damage flange surface.

f. Install protective covers on the evaporator and compressor connections. Plastic secured with duct tape makes an adequate cover if no heavy objects are set on the openings.

7. Support the compressor/motor assembly as indicated by the rigging specialist (see Step 5, p. 23). Do not lift the assembly; instead support the assembly to prevent it from slipping as the compressor foot and discharge connection flange bolts are removed.

8. Remove the compressor/motor assembly. Remove the locating dowel pins from the compressor foot and discharge flange connections shown in Figure 8, p. 20 and Figure 9, p. 20. Remove the nut on the dowel pin, place a bushing on the pin and then reinstall the nut.

CVHE-SVN04D-EN 25


Compressor Motor Mount Disassembly

If additional vertical clearance is required, the height of the compressor motor mount can be reduced. Use the following procedure:

1. Before cutting off the motor mount, first fabricate a 1/4-inch steel backing plate.

a. Cut the backing plate to shape and clamp it to the motor mount.

b. Drill four 1/4-inch holes through the motor mount and the backing plate as shown in Figure 16. These holes with bolts or roll pins installed will be used to align the components during reassembly.

c. Remove the backing plate.

2. Using an oxyacetylene torch, cut the mount as shown in Figure 16.

During reassembly, use the backing plate with bolts or roll pins to locate the pieces properly. After the pieces are located, Trane recommends welding the mount and backing plate in place.

� WARNING




Use the following steps to remove the economizer if additional horizontal clearance is required.

1. Support the weight of the economizer with a movable floor jack. Do not lift the economizer; simply support it. Economizer weights are provided in Table 10, p. 15. It is recommended that larger size economizers be lifted using overhead rigging.

2. If the unit has insulation, remove the insulation and loosen the bolts on the condenser liquid line flange. See Figure 17. Do not remove the bolts at this time. Cut the motor cooling drain line(s) if present and cut entering and leaving 5/8 inch OD copper oil cooler lines. Refer to Figure 13, p. 22.

3. Loosen the bolts on the evaporator liquid line flange. This connection is near the bottom of the evaporator. See Figure 17. Do not remove the bolts at this time.

4. Economizers are connected to the condenser shell via a bolted flange. See Figure 22, p. 31. Remove the bolts at this flanged connection.

5. Loosen the economizer vent pipe bolts which secure the vent pipes to the compressor interstage castings (unless the compressor has already been removed to gain vertical clearance.)

6. Secure economizer with appropriate rigging.

7. Remove the bolts from the condenser and evaporator liquid line connection flanges. Adjust the floor jack as necessary to support the weight of the economizer.

8. Remove the economizer vent pipe flange bolts to loosen the economizer. When the bolts are free, back the economizer away from the chiller. The economizer may tend to rotate off the jack towards the chiller. Be prepared to offset the rotation.

9. Remove the economizer orifice plates and mark them so they are reinstalled in their original position. The orifice with the greatest number of holes is to be located between the economizer and the evaporator. The orifice with fewer holes is to be located between the condenser and economizer.

10. Move the economizer away from the chiller and set it on a pallet. Cover all openings to prevent the entry of foreign material into the economizer, condenser and compressor.

Figure 17. Condenser liquid line flange

CVHE-SVN04D-EN 27


11. Use the reverse order to reassemble the economizer on the chiller. Be sure to install new gaskets at the appropriate joints.

12. Torque all bolts to specifications. Consult with your Trane service group for specific torques for your economizer design.

AdaptiView Display Arm Removal

� WARNING




Use the following steps to remove the AdaptiView™ display arm if additional clearance is required.

1. Cut tie wraps holding wires inside of control arm and remove wires from arm.

2. Remove 3-3/8” bolts from angle bracket attached to the control panel mounting bracket.

3. Use the reverse order to re-attach the arm to the control panel mounting bracket.

Control Panel Removal

1. Mark and disconnect incoming wiring to the control panel.

2. Remove the bolts from the bottom of the panel which secure the panel to the lower mounting bracket.

3. Loosen the bolts on the back of the panel which secure the panel to the top (suction elbow) mounting bracket. Refer to Figure 18, p. 28.

28 CVHE-SVN04D-EN


4. Two people will be needed to lift the panel clear of the chiller. Refer to Table 10, p. 15 for control panel weight. Steady the panel as the top retaining bolts are removed. Then lift the panel clear. Store the panel in a clean dry area.

5. Use the reverse order to reassemble the control panel.

Unit Mounted Starter Removal

Additional horizontal and vertical clearances may be obtained by removing the unit mounted starter on chillers so equipped. See Figure 19 (below) and Figure 20, p. 29.

Figure 18. Control panel mounting bracket

Figure 19. Unit mounted starter

CVHE-SVN04D-EN 29


The following procedure assumes the chiller is new and has never been installed and therefore there is no electrical power connected to the chiller. If there is power to the unit, follow proper lockout/tagout procedures, and any other applicable safety regulations regarding electric power.

� WARNING




1. Mark and disconnect the power wiring at the compressor motor terminal lugs inside the starter panel.

2. Mark and disconnect control wiring entering the starter panel. Remove the control wiring conduit from the starter panel.

3. Remove the bolts securing the bottom of the starter to the brackets on the evaporator.

4. To move the starter panel away from the chiller, it is recommended that a fork truck be used. Position the truck so that it is ready to take up the weight of the starter panel. The panel is top heavy and must be adequately secured before moving. Refer to Table 12, p. 16 for starter weights.

�WARNING

Heavy Objects!

Always place, assemble, and suspend modules/subassemblies one at a time. Placing, assembling, and/or suspending more than one module/subassembly at a time could result in death, serious injury, or equipment damage.

5. Loosen the bolts which hold the starter to the flange on the motor. Steady the starter panel as the retaining bolts are removed because the panel will tip forward. See Figure 19, p. 28.

Figure 20. Starter mounting bracket

30 CVHE-SVN04D-EN


6. Support the weight of the starter panel with the fork truck and carefully remove the starter panel from the chiller. Store the panel in a clean dry area free of any corrosive agents. When ready, reassemble the panel on the chiller in reverse order.

Condenser/Evaporator Disassembly

After the compressor assembly has been removed on separable shell units, the condenser and evaporator shells can be taken apart at flanged connections to reduce the horizontal clearance required for the chiller installation.

� WARNING

Heavy Objects!


1. Ensure that condenser and evaporator shells are securely supported on level ground. If not, shim under the bases.

2. Support the condenser with rigging using the lifting holes on the tube sheets. See Figure 21. Do not lift the shell, simply support it to avoid slipping as the bolts are removed from the connecting flange.

3. Remove the bolts from the flanges connecting the Evaporator tube sheet and Condenser Shell support (see Figure 22, p. 31). Then remove the bolts from the flanges connecting the shells.

Note: Some small shell combinations do not have flanged connections between shells.

4. Remove the two dowel pins located in the flange on each end of the shell tube sheet connections and lift the condenser clear of the evaporator.

5. Reassemble the evaporator and condenser shells in the reverse order.

6. Torque all bolts to specifications listed in Table 13, p. 34.

Disassembly of Chillers with Options

Heat Recovery

Use the following steps when disassembling chillers with auxiliary or heat recovery condenser shells to reduce the vertical clearance required for the chiller installation.

� WARNING

Heavy Objects!

Do not use cables (chains or slings) except as shown. Each of the cables (chains or slings) used to lift the unit must be capable of supporting the entire weight of the unit. Lifting cables (chains or slings) may not be of the same length. Adjust as necessary for even unit lift. Other lifting arrangements may cause equipment or property-only damage. Failure to properly lift unit could result in death or serious injury. See details below.

� WARNING




1. Support the auxiliary or heat recovery condenser with rigging using the lifting holes on the tube sheets. Do not lift the shell; simply support it to avoid slipping as the bolts are removed from the connecting flanges.

2. Remove the bolts from the flanges on the interconnecting piping and flanges connecting the auxiliary heat recovery condenser and condenser tube sheets.

3. Remove the bolts from the flanges on the interconnecting piping and the flanges connecting the shells.

4. Lift the condenser clear of the unit.

5. Reassemble the condenser in the reverse order. Install new gaskets at the appropriate joints.

6. Torque all bolts to torque specifications listed in Table 13, p. 34.

7. Remove and coil up sensors.

Free Cooling

Use the following steps on free cooling units to reduce the vertical clearance required for chiller installation.

1. Support the piping and free cooling valve between the condenser and suction elbow with rigging similar to that used for removing the suction elbow. Do not lift the piping; simply support it to avoid slipping as the bolts are removed from the connecting flanges. (Typical rigging for lifting the suction elbow can be seen in Figure 15, p. 24.)

2. Remove the bolts from the flanges.

3. Lift the piping clear of the unit.

4. Reassemble the piping in the reverse order. Install new gaskets at the appropriate joints.

5. Torque all bolts to torque specifications listed in Table 13, p. 34.

CVHE-SVN04D-EN 33

Compressor/Motor Reassembly

It is important to remove used O-rings and gaskets and clean joints before reassembling the compressor with new O-rings and gaskets. All necessary replacement O-rings and gaskets are supplied by the factory when the compressor doweling or separable shell options are ordered.

Use the following procedure to reattach the compressor/motor assembly to the chiller.

1. Remove the protective covers on all compressor, condenser, and evaporator connections. Clean all mating surfaces using Loctite® “Chisel” cleaner or CRC® Industrial Gasket Remover. Completely remove old sealing compound from O-ring grooves. Use Loctite “N” primer for final surface preparation.

2. Refer to CTV-SB-66F (General Service Bulletin: CenTraVac O-Ring and Flange Sealant), or the most recent version, for proper installation of gaskets, O-Rings, and Loctite sealant. Install a new O-ring on the compressor discharge connection mating surfaces. Use Loctite 515 “Gasket Eliminator” to lubricate the O-ring and provide additional sealing. This is the only sealing compound recommended by Trane for use on O-ring joints. To use this sealing compound, apply a light bead (approximately 1/8” in diameter) to the O-ring groove, insert the O-ring and then apply a light bead to the O-ring. Also apply a 1/8” bead of sealing compound between the O-ring groove and the bolt hole circle. The parts can now be assembled.

3. Lift the compressor/motor assembly into place. Insert the bolts in the compressor foot and discharge flange connections. Before tightening any of these bolts, reinstall the dowel pins in the compressor foot and discharge flange.

4. Tighten the compressor foot and discharge flange bolts. See Table 13, p. 34 for bolt torque specifications.

5. Install and tighten the motor mount bolts. See Table 13, p. 34 for bolt torque specifications.

6. Remove the lifting equipment.

7. Set up dial indicators on the compressor end of the compressor/motor assembly. See Figure 23. The dial indicators are used to monitor horizontal and vertical movement of the compressor/motor assembly when the suction elbow retaining bolts are tightened. Support the dial indicators from the condenser or from a floor stand.

Figure 23. Suction elbow flange bolts

34 CVHE-SVN04D-EN


8. Clean the suction elbow flange surfaces and O-ring grooves per Step 1, p. 33. For the evaporator to suction elbow joint, use Loctite® 515 per Step 2, p. 33. For the suction elbow to compressor joint, use 1/8” GORE-TEX® Joint Sealant placed approximately 1/8” in board of the O-ring groove. This is used in addition to the O-ring. As an option, Loctite 515 may be used in place of GORE-TEX. However, great care must be taken to prevent the sealant from entering the first stage IGV housing. Refer to CTV-SB-66F (General Service Bulletin: CenTraVac O-Ring and Flange Sealant), or the most recent version.

9. Lift the suction elbow into place using a sling or chain-fall hoist.

10. Install the suction elbow retaining bolts.

11. Tighten the retaining bolts only “hand tight”. Tighten two retaining bolts, 180 degrees apart at the compressor connection. Then tighten two bolts, 180 degrees apart at the evaporator connection. Alternate between connections until all retaining bolts are tight. Monitor the dial indicators to insure that there is no more than 0.010 inches of compressor movement. If there is more movement than this, loosen all of the bolts, “zero” the dial indicators and repeat the procedure. Figure 23, p. 33 illustrates the bolt tightening sequence.

12. Reconnect the economizer vent pipes. Be sure to clean the mating surfaces and use new gaskets on the connections. Tighten the flange bolts just enough so that the gasket material just begins to extrude from between the flanges.

13. Reinstall all other chiller components which were removed. Reconnect the inlet vane linkages.

14. Torque all bolts to specifications listed in Table 13.

15. Reconnect the previously cut compressor/motor oil supply and return lines and the motor cooling lines using the factory-supplied couplings.

Brazing

� WARNING

Hazard of Explosion and Deadly Gases!

Never solder, braze or weld on refrigerant lines or any unit components that are above atmospheric pressure or where refrigerant may be present. Always remove refrigerant by following the guidelines established by the EPA Federal Clean Air Act or other state or local codes as appropriate. After refrigerant removal, use dry nitrogen to bring system back to atmospheric pressure before opening system for repairs. Mixtures of refrigerants and air under pressure may become combustible in the presence of an ignition source leading to an explosion. Excessive heat from soldering, brazing or welding with refrigerant vapors present can form highly toxic gases and extremely corrosive acids. Failure to follow all proper safe refrigerant handling practices could result in death or serious injury.

Except as noted below, braze with the following filler metals:

• Braze all copper-to-copper joints with A.W.S. BcuP-6 filler metal.

• Braze all copper-to-brass joints with A.W.S. BcuP-6 filler metal using white or black brazing flux.

• Braze all other joints with A.W.S. Bag-28 filler metal.

Bleed dry nitrogen through the lines while brazing to prevent the formation of oxides which can contaminate the oil and refrigerant systems.

Note: Use silver soldering with 96% Sn-4% Ag (for example, J.W. Harris Co. Stay Brite®) to replace brazing when the heat from brazing would be detrimental to the immediate or nearby parts.

Examples:

1. Joints next to threaded joints in which the copper or brass threads become too soft and/or Loctite® loses its sealing capability due to excess heat.

2. Joints next to valves in which the valves cannot be taken apart or are not recommended for brazing.

Final Installation Procedures

After the chiller has been moved to the equipment room and reassembled, complete the final installation procedures (including piping, wiring, evacuation, leak testing, and charging). The chiller may then be started under the supervision of a Trane Service engineer. For additional information regarding compressor disassembly and reassembly, refer to CVHE-SB-10B (General Service Bulletin: Compressor Doweling), or the most recent version.

W A T E R T R E A T M E N T ÐDGUV"RTCEVKEGUÑ This document is designed to guide HYATT HOTEL CORPORATION Hotel Engineers to manage the water treatment program in order to protect the associated HVAC Assets from Scale, Corrosion and Biological Growth at their facility. The following standards outline the quality and level of water treatment performance, that is required at all HYATT facilities. It is the intent of the program to set minimum standards that must be maintained by the Hotel Engineer and the Water Treatment Supplier to ensure a safe environment that protects the HVAC systems from scale, corrosion and biological fouling at cost effective price. The program requires that the Hotel Engineers become knowledgeable with regards to the water treatment program and the acceptable ranges for their specific HVAC systems. The Hotel Engineer is responsible for verifying that the Chemical Treatment Supplier complies with all specifications in this standard. The Chemical Treatment Supplier is responsible to educate the Hotel Engineers and protect all treated systems to the best of their ability.

The primary goals, in no order of preference, of the service-oriented, water treatment program are as follows:

Minimize or eliminate safety hazards and chemical handling by HOTEL personnel.

Provide professional, knowledgeable, and involved water treatment service personnel.

Accurately monitor the program results and communicate appropriate recommendations with quantifiable, business-oriented justifications. Service reports from the water treatment supplier shall provide the required water treatment test data to indicate the HOTELÓu"eqornkcpeg"with the water treatment ÐDguv"RtcevkeguÑ"fqewogpv.

Reduce the overall energy/utility consumption through improved heat transfer efficiency and water quality. This is accomplished by improving the make-up quality; reducing system contamination; and minimizing scale, corrosion, fouling, and microbiological growth, which create deposits on heat transfer surfaces.

Minimize the water usage rates by operating with maximum cycles of concentration levels, the elimination of leaks, and evaluating alternative water sources as the make-up for the cooling systems.

Minimize the repair and maintenance costs associated with the replacement and cleaning of equipment due to scale, corrosion, fouling, or microbiological activity.

Thoroughly train Hotel personnel on the implementation and control of the program(s) where applicable.

T O W E R W A T E R SYST E MS T R E A T M E N T Chemical Inhibitor The chemical inhibitor chosen should either be based on the ability to control scale formation while running with the highest cycles of concentration, or be more of a corrosion control program in soft water applications. There are (3) classifications of makeup water sources that have different chemical program needs. They are:

Soft Water Program with < 0.5 ppm Ortho Phosphate present in the makeup source

Soft Water Program with >0.5 ppm Ortho Phosphate present in the makeup source

Hard Water Program (LSI in the Tower that exceeds 1.7 upon cycling) It is the responsibility of the water treatment company to analyze the makeup water source to define what category make up water source is being used by the Hotel. A general guideline for Soft Water Programs should those water sources that upon cycling in the tower the LSI do not exceed 1.6.

Soft Water Program with < 0.5 ppm O rtho Phosphate The inhibitor should be a phosphonate based program (HEDP/ZINC/azole/polymer). HEDP acts as the scale inhibitor and will contribute Ortho Phosphate to help with the corrosion protection. Vjg"wug"qh"PcneqÓu"RUQ"ecp"dg"wugf"cu"cp"cnvgtpcvkve program as long as the performance standards for corrosion control are met. The phosphonate level should be maintained at a minimum of 3.0 ppm as HEDP using the HACH method. The zinc level should be at a dosage to maintain the expected corrosion rates. Before zinc is used, the discharge of zinc should be investigated to make sure this inhibitor can be safely discharged. The inhibitor should be fed based on water meter usage or by direct control method.

Soft Water Program with > 0.5 ppm O rtho Phosphate The inhibitor should be a phosphonate based program (PBTC/ZINC/azole/polymer). PBTC acts as the scale inhibitor and will contribute little if any Ortho Phosphate as there will be sufficient Ortho Phosphate in the makeup source to minimize corrosion upon cycling the Cooling Tower. Vjg"wug"qh"PcneqÓu"RUQ"ecp"dg"wugf"cu"cp"cnvgtpcvkxg"program as long as the performance standards for corrosion control are met. The phosphonate level should be maintained at a minimum of 3.0 ppm as PBTC using the HACH method. The Ortho Phosphate levels limits in the cooling tower need to be defined by the Water Treatment Supplier. Additional polymer may be required to manage the high levels of Ortho Phosphate in the cooling tower. The inhibitor should be fed based on water meter usage or by direct control method.

Hard Water Program The inhibitor should be a phosphonate based program (PBTC/azole/polymer). PBTC is the most resistant inhibitor to oxidizing biocides and holding time in cooling towers. The phosphonate levels should be maintained a minimum of 1.06 ppm (3.0 ppm as PBTC) using the HACH


! - 5 -

method. The cycles should be maintained so that the LSI does not exceed 2.5. The inhibitor should be fed based on water meter usage or by direct control method. In very hard water make up conditions, consideration should be given to the use of softened water to manage hardness or acid to control pH. The use of softened water or acid requires financial justification given the high capital cost and/or safety concerns. The use of acid should be the last resort as part of the water treatment program due to safety concerns. Any use of acid needs to be reviewed by HYATT HOTEL CORPORATION. The uses of liquid or solid programs are considered acceptable as long as they meet the specifications as outlined in this document.

Azole Î Copper Corrosion Inhibitor The only chemical protecting copper in your system is azole. The most popular azoles used are tolytriazole (TT), benzotriazole (BZT), or HRA (halogen-resistant azole). You must maintain some level of free and available azole, or you have no copper corrosion inhibition.! With the use of enhanced tubes, the importance of controlling copper corrosion is critical. The minimum free and available azole level in the condenser water system should be 1.0 PPM (tested by the HACH method).

Dispersants The use of dispersants is required for any of the above programs listed. In most cases the dispersant is blended with the inhibitors. The dispersant type is at the water treatment uwrrnkgtÓu discretion. It should be noted that any scale formation due to the neglect of the water treatment suppliers program will be cleaned at no cost to the Hotel. A minimum of 8.0 ppm dispersant should be in the tower at all times.

Cycles of Concentration

Hyatt Hotel Corporation has instituted a program to run all cooling towers at a minimum 5 cycles of concentration based on magnesium cycles. The objective is to minimize the amount of makeup water required by the facility while maximizing the mechanical systems efficiency with the highest level of scale and corrosion protection possible. The cycles of concentration, (CC) will vary with the application and available city make up water supply. In all cases, the CC should be determined with each sites regular routine testing, The CC must be determined using the elements of magnesium or silica and the ratio that is found between the makeup and cooling tower treated water systems. Automatic system blow down will be control by the use of a digital display, conductivity control meter. Adjustments will be made as required to maintain desired CC and confirmed with magnesium or silica ratio testing as outline later. If (5) or better cycles cannot be achieved using the required chemical treatment program outlined earlier, a report showing what investment is needed to get to 5 cycles is required by the water treatment supplier. Hyatt Hotels will evaluate if the investment is cost effective and should be implemented.

Any of the programs listed above should be maintained in such a manner to prevent scale formation and achieve corrosion rates no greater than 1 mil/yr (MPY) for mild steel and 0.1 MPY for copper by the use of coupon studies conducted a minimum of every 90 days. The use of molybdenum as a part of the program or a trace testing method should be evaluated for discharge limits prior to use. In many municipalities, molybdenum is not allowed to be discharged. Each facility will review annually if the cooling tower is eligible for evaporation credit. Even if the facility is currently receiving evaporation credits an annual audit will be done to validate that the proper credit is being received. In some cases Silica might be the limiting factor when considering cycles of concentration. The silica levels in the cooling tower should not exceed 150 ppm. If this is the case, please contact HYATT to determine the correct course of action when treating the cooling tower. There might be circumstances where the makeup water quality does not fit into the (3) classifications outlined earlier. Any anomalies should be presented to HYATT HOTEL CORPORATION for review.

Tower Dual Biocide Program:

The most important component of the treatment of cooling towers is the biocide program. Over 90% of failures in cooling systems are due to microbiologically-influenced under deposit corrosion. In addition, the lack of control of this aspect of the program can lead to the growth of the dangerous Legionella bacteria. This program must be controlled to keep total bulk water aerobic counts below 10,000 cells/ml and total anaerobic counts below 50 cells/ml at all times. The biocide program must be a dual, alternating program where two biocides are employed. For bulk water sterilization, a halogen type biocide is used, while a non-oxidizing biocide is used to control anaerobic and slime forming type dcevgtkc0""Rngcug"tgogodgt"vjcv"ÐdkqekfgÑ"ogcpu"Ðmknnu"lifeÑ0""Vjgug"rtqfwevu"pggf"vq"dg"tgurgevgf"htqo"c"uchgv{"uvcpf-point.

Oxidizing Biocide Î Primary Biocide The oxidizing biocide of choice is a liquid stabilized bromine-based product. A pellet hydantoin based bromine biocide is acceptable if there is business justification to use and properly feed this product. Bromine should be fed a minimum of two to three times per week and achieve a 1 PPM free halogen residual at the end of the feed cycle. In some locations, continuous halogenations may be required to control the bacteria counts. If continuous halogenation is used, the control levels should be within the range of 0.2-0.3 PPM free halogen. Halogens are oxidizing agents, so if you over-feed them they will become corrosive to the system. The bromine feed frequency must be adjusted to insure a bulk water total aerobic bacteria count < 10,000 cells/ml. If your bacteria counts are consistently zero cells/ml you may be over-feeding the halogen. All liquid halogen products must have a degasification head on the chemical feed pump. All erosion feeders must have a pressure release valve.


! - 7 -

Non-Oxidizing Biocide Î Secondary Biocide A non-oxidizing biocide needs to be fed a minimum of once per week for the control of under deposit bacteria and biological slime. This is not necessarily fed to control bulk water bacteria. Bulk water bacteria are controlled by halogen. If your biological counts always increase dramatically after the addition of these products, you may already have a large population of slime-forming bacteria in the system. The biocide of choice is either Gluteraldhyde fed at a level of 120 PPM of a 45% solution, or Isothiazoline fed at a level of 100 PPM at a 1.5% solution once per operating week.

N O T E The uses of Cationic Biocides are prohibited. Every heat exchanger should see biocide feed weekly0""Kh"{qw"jcxg"Ðkfng"ejknngtuÑ"{qw"owuv"circulate water through the condenser barrel during the biocide feed schedule. Failure to do so can result in biologically-induced under deposit corrosion conditions of the condenser tubes that could lead to tube failure.

C H I L L E D W A T E R SYST E MS T R E A T M E N T The inhibitor of choice should be a molybdenum or molybdenum/silica based program along with the use of azole and a polymeric dispersant. Where nitrite is already used, this program can continue and be maintained at levels within the following ranges:

Molybdenum 100-120 PPM (Preferred molybdate-based program)

Molybdenum 40-60 PPM (for molybdate/silica-based program)

Silicate 20-30 PPM above city water silica levels.

(for molybdate/silica-based program)

Nitrite (NO2) 500-750 PPM

Free and available azole 5-10 PPM

pH 8.0-10.3

Conductivity <4,000 MMHS

Iron <1 PPM

Copper <0.5 PPM

If the iron and/or copper levels are above their ranges, then filtration should be considered to remove iron, copper, and suspended solids. In many cases, a simple cartridge filter or cartridge filter/pot feeder combination is all that is needed. If the system volume is very small changing the water could be considered an option to bring down the The chilled water loop needs to be checked by a laboratory for biological activity quarterly. If the total bulk water biological counts are above 1,000 cells/ml, or Anaerobic Bacteria is above 50 cells/ml., you need to shock the system with a non-oxidizing type biocide. Two proactive additions of a non-oxidizer (preferably copper-free Isothiazoline and Gluteraldhyde) should be performed at least once per year per product to the loops. It is recommended that all chilled water make-up lines be equipped with a water meter to determine the amount of water loss. Closed loop systems should have a water loss of less than 10% of the system volume per year. If Nitrite is used, additional biocide may be needed to control the biological levels within the guidelines established above.

C H E M I C A L F E E D E Q UIPM E N T The most important aspect of a well-run chemical program is the level of automation. Given the minimal man-power available, HYATT HOTEL CORPORATION wants, as a minimum, the following chemical feed equipment for the cooling, chilled, hot water and steam boiler systems, where applicable. HYATT HOTEL CORPORATION will evaluate new equipment technologies if there is business justification to do so.

Cooling Towers

Containment systems for all chemicals must be a minimum of 10% greater than the volume of chemicals.

Make-up (MU) and/or blow down (BD) water meters must be compatible to send a pulse signal(s) to a controller to feed the scale/corrosion inhibitor based on the water usage rate. It is always preferred to have a water meter with an actuating pulse on the make-up water source. Direct measurement of the inhibitor is encouraged if there is business justification for this type of control.

Blow down solenoid for automatic blow down control

Chemical feed controller " Internet ready (Desired on larger Tower Systems)

Four-position corrosion coupon racks with rotometer. The goal is to have 5-7 feet-per-second flow rate at all times.

Pumps " To feed scale and corrosion inhibitor " To feed a liquid bromine product; the pump must have a degasifying head to prevent

priming problems or use a peristaltic pump. If a solid bromine product is used, an erosion feeder equipped with a solenoid valve and pressure relief valve is needed instead of a chemical pump. The solenoid valve should be activated based on the controller biocide timer.

Closed Hot and Chilled Loops

Make up water meter(s) to monitor water usage.

Four-position corrosion coupon racks with rotometers. The goal is to have 5-7 feet-per-second flow rate at all times.

Pot feeders

Cartridge filter/pot feeder that can withstand the temperatures (optional, yet recommended)

Corrosion Coupon Analysis !

It is the intent of this section to require separate corrosion coupon monitoring on all water systems (hot, chilled, condenser, open, closed, primary and secondary, steam condensate). Each corrosion coupon rack installation will have metal samples for mild steel and copper. All coupons must be of the non-pretreated type. The corrosion coupons and analysis will be done by the water treatment supplier at no additional charge.

All systems will have corrosion coupon racks installed.

All systems must have (4) coupon sites per rack.

Each coupon used will be a non-pretreated metal pre-weighed to the 4th decimal place.

There will be mild steel and a copper coupon installed for a 90-day exchange interval. ASME guidelines will be used to determine if longer exchange intervals can be used.

Mild Steel coupons will be installed before the copper corrosion coupons. " Copper corrosion rates are expected to be less than 0.1 mpy " Mild Steel corrosion rates are expected to be less than 1.0 mpy for cooling

systems and < 0.5 mpy for closed loop systems

Chemical introduction points must be fed downstream of the coupons.

Visual flow rate monitoring meters must be installed on each coupon rack to ensure proper flow control and visual flow verification, in each coupon rack installation.

Restriction devices or flow control valves must be installed to maintain a minimum of 5 GPM (gallons per minute) and a maximum of 7 GPM in coupon racks at all times *hqt"-Ñ"eqwrqp"tcemu+0

Steam Boiler System Every steam boiler system should have a water softener present to minimize the potential for scale formation. The chemical should be fed as follows:

Sulfite and Polymer should be fed directly to the storage section of the DA Tank or feed water tank as close to the makeup water source as possible. Sulfite should be fed via feed water pump activation or based on softened city water make up. If feed is based on softened water makeup, the chemical pumps must activate when any make up flow is

going to the tank. An injector should be used so that chemicals are fed in the water storage area at a point of mixing to allow best distribution.

Caustic, if applicable, Phosphate and amine (DEAE preferred) should be fed to the feed water line after the feed water pumps or directly to the boiler. An injector should be used so that the chemicals are fed in the water stream and mixed as best as possible. Both Caustic and amine should be fed based on feed water pump activation.

Chemicals should be fed directly from the drum or mini bulk tank to minimize chemical handling. If multifunctional chemicals are used (blended all in one products), the chemical residual guidelines must still be met. In many cases there are few instances where just one formulation can be used.
