SAFETY ISSUESThere are three degrees of safety hazards that are identified throughout this manual as WARNING (where the situation will result inpersonal injury), CAUTION (where personal injury might occur), and ATTENTION (where minor personal injury and/or property dam-age could happen). Please understand and respect those identifications.

WARNING: The PY units operate on a high voltage with moving parts (at high speed) which can lead to serious injuries and/or damage to the unit. Never attempt to service the unit unless the main electrical power supply has been disconnected.

CAUTION: Extra care should be observed when installing, test running, adjusting, servicing, or maintaining the unit as thehazard of explosion, fire, electrical shock, and potential personal injury and property damage are present.

When performing any task pertaining to the installation and maintenance of the unit, the skilled technician should observe all theapplicable safety measures (wear of safety helmet, boots, gloves, and goggles. Use of proper handling materials for brazing and useof wet cloth for quenching. A fire extinguisher should be easily accessible etc.). He should also read all the instructions and informationin this Manual prior to attempting to perform any installation or servicing of the unit.

All applicable local codes should also be observed.

INSPECTION FOR DAMAGEThe unit should be carefully inspected visually for any sign of physical damage due to mishandling. Whenever a damage is detected,please indicate it on the corresponding delivery note before you sign it and inform your nearest “Zamil” office.

GENERALThese units are shipped completely assembled, charged, and wired. They do not require any field installation of refrigerant tubing.Units require external power, thermostat wiring, condensate drain piping and ducting as applicable.

Size of unit for an installation should be based on a heat gain calculation made according to applicable standards. Units must also beinstalled in accordance with regulations of the "National Fire Protection Association" and local electrical codes. Where local regulationsconflicts with the instructions in this manual, installer should adhere to local standards.

Prepare your concrete pad or steel stand based on the corresponding dimensions. Remove shipping protective covers and woodencrating and lift unit from base and place in position with suitable vibration isolators.

All field installed accessories are to be installed by the customer.

LOCATION OF UNITWhen selecting the location for the unit, the following points should be kept in mind:

1. Provisions for a concrete pad or steel stand base.

2. That the terrain allows for drainage away from the unit.

3. If the unit is to be roof mounted, inspect the roof for load bearing capacity. The roof should have sufficient structural strength to carrythe weight of the unit.

4. Install unit on vibration isolation pads, i.e. on rubber mounting pads.

5. Availability of electric power.

6. To position the unit for unrestricted air circulation of the condenser air inlet and to prevent any possibility of air recirculation from thecondenser fan discharge air (see figure on next page).

7. Check minimum clearances required for your unit, with regard to walls, or other obstructions (see figure on next page).

8. Air cooled equipment should not be installed under low structural overhangs which can cause condenser air recirculation or restric-tion. Observe minimum of clearance (see figure on next page).

9. Care should be taken to prevent air from other sources from entering condenser, if this air is at a high temperature.

10. Level the unit on its final location and be sure that the levelling tolerance is ±5 mm per linear meter in any direction.

CAUTION: Do not install the unit as indoor unit, install it in an open area, and unit air inlets must not be located near exhaustvents or other source of contaminated air.

MICROPROCESSOR CONTROLLERThese Packaged units are provided with a microprocessor control board incorporating the following features:

• BALANCE LOADING OF COMPRESSORS: The unit’s electronic control automatically operates lead/lag se-quence of compressors. This is to load the compressors evenly over long periods of operation. If required however,compressor-1 can also be set to always lead. In this case, compressor-1 always starts first and stops last.(Selectable through dip switch setting on control board).

• PUMP DOWN FUNCTION: In units equipped with pump down system, the controller provides the time delaybetween solenoid’s opening and compressor starting to equalize the pressure in the system necessary for com-pressor to start-up. (Selectable through dip switch setting on control board).

• COMPRESSOR ANTI-RECYCLING PROTECTION: The controller has a built-in 3 minutes minimum off timer forcompressor. This is for compressor protection in case of accidental manual re-set or immediate re-cycling ofthermostat due to load demand.

• COMPRESSOR LOCK-OUT FUNCTION: If any of the unit’s safety control trips due to abnormal conditions, theelectronic controls locks out the compressor after a pre-determined timing preventing a re-start unless attended bya qualified service technician. The unit can be re-started through thermostat re-set after ensuring safe systemconditions.

• FAULT DIAGNOSTICS: In case of system fault, LED’s on the board emits a flashing signal indicating where thefault is. This is to guide the service technician in identifying the fault.

• DIGITAL I/O’s: The unit’s control board is compatible to operate with a DDC controller or any standard 24V a.c.thermostat commercially available.

• SEQUENTIAL CONTROL: With input signals from the thermostat, the motors in the equipment is started insequential order: supply fan – condenser fan – compressor; at a pre-determined timings.

ELECTRONIC THERMOSTAT

18

General information: Electronic thermostat shall control one or two stage heating and cooling applications. Thethermostat normally displays room temperature and mode of operation.The temperature can be set by up/down buttons for both cooling and heating cycles. The thermostat also allows youto select continuous fan operation, or have the fan on intermittent operation with the equipment.The thermostat is best located about 1500 mm (5 Ft.) above floor level, on a partition wall (not an outside wall), and shouldnot be exposed to direct light from lamps, sun etc. It should be in return air stream, away from supply air registers/diffusers.

• Single/dual stage - Cooling & heating.

• Low voltage control - 24 VAC (nominal).

• Room temperature display - in 0C or 0F.

• Mode of operation - FAN/COOL/HEAT/AUTO.

• Fan mode - ON: Continuous fan operation; AUTO: Fan operates ON/OFF with compressor.

• Heating & cooling setpoint is permissible.

• Temperature set button - Up for increasing & down for decreasing temperature.

• Built-in compressor fault & clogged filter indication led lights.

• Remote sensing function as an option. Duct sensor is provided with the thermostat.

Scroll compressors are designed to operate in single direction only. Hence, care has to be taken to ensure correct rotationwhen the system is operated. Verification of correct rotation is by observing that the suction pressure drops and dischargepressure rises when compressor run. Reverse rotation results in abnormal sound, as well as, substantially low current drawand by interchanging power supply wire L1 & L3 will correct this problem.The operation of the air conditioning unit is controlled by a 24VAC electronic control board.

GENERALThe thermostat normally displays room temperature and mode of operation. The five buttons on the front of the unit allowcomplete control of the thermostat. The thermostat also allows to select continuous fan operation (useful when using an aircleaner) or have the fan come on with the compressor.

SWITCH FUNCTION- On/Off Key : Switch the system On or Off.- Up Key : To increases the set temperature.- Down Key : To decreases the set temperature.- Mode Key : Changes the mode to Fan, Cool, Heat or Auto.- Fan Key : Changes the Fan Operation to Auto or Continuous.- °C/°F selection : By pressing Mode & UP key together, toggles between °C to °F or vice versa.

USER CONTROLSMode:Select the desired mode of operation by pressing of the mode button:

Fan: In this mode of operation, the compressor will be in inactive state. Display shows room temperature. Fan will be running.

Cool: In this mode of operation, the compressor will be ON after a delay depending on the differential of room tempera-ture & Set temperature.

Heat: In this mode of operation, Fan is ON.

Auto: In auto mode, thermostat provide automatic changeover from heating to cooling mode & vice versa. Thermostatautomatically switches to maintain the desired temperature.

DIP SWITCH OPTIONS AND FUNCTIONSThere are 4 small DIP (Dual in line package) switches on the back of the circuit board which must be configured by theinstaller.

MAINTENANCE INSTRUCTIONSAIRFLOW ADJUSTMENT (Applicable for PY075 - PY360 only)The airflow could be adjusted by adjusting pulleys of blower motor or belt tension with proper mounting and alignment of the pulleys:

• Refer to fan performance tables in the catalog for selecting applicable airflow, RPM and brake horse power at specified staticpressure.

• Select the appropriate drive as per motor and blower characteristic in the catalog.

• The set screw shall be loosened to make the pulley moving.

• Adjust pulley’s diameter, opening counter clockwise to reduce RPM and further reduce airflow, while closing clockwise increasesRPM and airflow.

• Tighten the set screw and then install the belts.

• Test the unit operating airflow for further adjustment.

CRANKCASE HEATER• Periodic checking for proper operation or crankcase heater is highly recommended as follows:

a) Check continuity of the heater using multimeter device.

b) Check grounding of the heater by Meggar device (to prevent electrical hazards).

c) Observe whether the heater is warming down the compressor near the oil sump.

CLEANING OF COILS & FILTERS• Turn off the power supply.

• Take out access panel of evaporator coil.

• Remove the filter from its access panel.

• Protect electrical components and motors from water washing.

• Clean the coil by flushing water by pressure washer followed by compressed air from supply to return direction.

• Filter shall be cleaned every six month, in some hygienic application it is recommended for replacement.

• Cleaning drain pan and trap is recommended once in a year to prevent bacteria growing under the coil.

BELT TENSION TESTING PROCEDURE INSTRUCTION (Applicable for PY075 - PY360 only)To determine the lbs. force required to tension a drive, you simply do the following:

1. Measure the Belt span as shown.

2. Divide belt span by 64 to get belt deflection needed to check tension.

3. Set large "0" ring on span scale at required belt deflection. This scale is in 1/16" increments.

4. Set small "0" ring at zero on the "Force Scale" (plunger).

5. Place the larger end of the tension checker squarely on one belt at the center of the belt span. Apply force on the plunger until thebottom of the large "0" ring is even with the top of the next belt or with the bottom of a straight edge laid across the sheaves.

6. Read the force scale under the small "0" ring to determine force required to give the needed deflection.

7. Compare the force scale reading with the correct value for the belt style and cross section used, as given in table on next page.The force should be between the minimum and maximum values shown.

8. If there is too little deflection force, the belts should be tightened. If there is too much deflection force, the belts should beloosened.

Note: Tension new drives at the maximum deflection force recommended. Check the tension at least two times during the first day'soperation as there normally will be a rapid decrease in belt tension until belts have run in. Check the tension periodically after the firstday's operation and keep tension in recommended area. The correct operating tension for a V-belt drive is the lowest tension at whichthe belts will not slip under the peak load conditions. Shafts must be adequate for the tensions required.
