1.1 The PRIMECENTER LC Rack

With the PRIMECENTER LC (Liquid Cooling) Fujitsu Siemens Computers has added a new, water-cooled model to the service-proven PRIMECENTER Rack line.

It offers the same features and advantages as the other models of the PRIME-CENTER line (see section 1.2 on page 7), plus a new, future-oriented cooling concept:

● The cooling system provides the enormous cooling capacity of up to 13.5 KW.

● The closed air circuit means that no heat is emitted into the room.

● The cooling system is inherently safe, so no water can reach the server area. Special bayonet connections ensure that even while the system is being attached to the chilled water circuit no liquid can escape.

The PRIMECENTER LC Rack is consequently able to cope with future instal-lation requirements of servers and storage systems which emit a large amount of heat.

1.2 Advantages of the PRIMECENTER Line

Sophisticated Transport Concepts

The height of the 38 HU PRIMECENTER LC Rack allows it to fit through a normal, 2-meter high door without having to be tipped, even if it is still on the delivery palette. This not only makes the rack easier to transport but also allows it to be delivered with components such as server or storage expansion units already installed and configured as specified by the customer. It also makes it easy to move the PRIMECENTER LC Rack to a new location on its rollers. The internal cabling is complete.

46 HU PRIMECENTER LC Racks are delivered without the rack components pre-installed. The components are mounted in the rack after it has reached its location where it is to be installed. These racks can also be easily moved to a new location on their rollers. The transport concept for the 46 HU PRIME-CENTER LC Racks assumes that the customer does not know about individual local conditions such as the height of the door frame or the existence of elevators etc.

Uniform Installation Concept

The mounting location concept is uniform for the entire PRIMECENTER line.Regardless of whether you install a component in a conventional PRIME-CENTER Rack or in a new PRIMECENTER LC Rack, the installation is always the same.

PRIMECENTER Racks are based on internationally standardized 19-inch rack technology. This means that you can install not only components from Fujitsu Siemens Computers, but also other vendors’ 19-inch components.

Rack components can be mounted horizontally using sliding rails or telescopic rails. Mounting components using telescopic rails and the corresponding cable management system allows maintenance and repair work to be carried out easily and cost-effectively and supports hot-plug solutions.

8 PRIMECENTER LC

Advantages of the PRIMECENTER Line Preface

High Capacity

Ideal use is made of the space available. In addition to the horizontal mounting locations at the front and rear, vertical mounting locations are available for components of up to 290 mm in depth (240 mm + 50 mm cabling).With PRIMECENTER LC Racks up to 2 x 2 HU, mounted vertically, can be used. This means, for example, that horizontal height units do not have to be occupied for hubs, modems or switches.

If cable management is not used, the full depth of this mounting location can be utilized.

Universality

The new PRIMECENTER Rack can be configured quickly and consistently using a single software tool with all products from Fujitsu Siemens Computers (PRIMERGY, PRIMEPOWER, BS2000 and all associated peripherals, FibreCAT and storage subsystems). This guarantees that the needs and requirements of users can be implemented as required. Even third-party products can be installed in the PRIMECENTER Racks with their original assembly kits plus adapters from Fujitsu Siemens Computers.

Optimized Cabling

The sophisticated, patented cable management system ensures safety, clarity and user convenience. PRIMECENTER Rack Systems have an integrated cable guide as well as articulated cable guides, which are not only service-friendly but also decisively improve operational reliability and serviceability. Cables are not forced below their minimum bending radius and are laid neatly to avoid confusion. Even in the event of maintenance, faster re-availability of the affected systems is guaranteed because no cables in the cabinet can fall or become twisted.

Because the cables are routed along the side of the rack components using articulated cable guides or cable guides with cable clips, the connection side of the rack components remains tidy, making it is easy to see where each cable leads. A distinction is made between two types of connection

– A connection via an articulated cable guide

– A direct connection

PRIMECENTER LC 9

Preface Advantages of the PRIMECENTER Line

An articulated cable guide is used together with rack components that are mounted in the PRIMECENTER Rack using telescopic rails or sliding rails. This combination allows rack components to be pulled from the rack without the cables having to be disconnected first and therefore allows device components to be replaced during operation in hot-plug solutions.

With other rack components, cables are connected directly. This means that the cables can be shorter, but hot-plug solutions are either not or only partially supported.

Excess lengths of cable can be fastened at certain locations within the PRIMECENTER Rack using a cable guide with cable clips.

Coordinated Ventilation Concept

To ensure reliable operation it is essential to provide adequate ventilation for all rack components. To ensure that this is achieved, all rack components with their own ventilation concept are coordinated with racks of the PRIMECENTER line and consequently guarantee a uniform overall solution. The ventilation concept is such that fresh air is drawn in at the front and the warm air is expelled at the rear. In the case of conventional PRIMECENTER Racks a perforation rate of more than 60 percent on the front doors ensures a high air throughput. With PRIMERGY LC Rack Systems powerful fans draw in the warm air at the rear, guide it through the cooling unit, and then direct the cooled air to the front again.

Service-friendliness

The 19-inch devices are mounted on sliding or telescopic rails. The marking and numbering of the height units simplifies the assembly when installing and adding components.

Thanks to the cabling and the stable construction, not only is the availability increased, but maintenance and downtimes are also shorter for conversions and upgrades.

10 PRIMECENTER LC

Advantages of the PRIMECENTER Line Preface

Standards

Each rack can be equipped with an AC power connection that complies with European and American standards. At least two socket strips and two AC main power connections can be configured for phase redundancy. Because of the high leakage current of a fully configured rack, CEE-compliant plug connectors are used. Connection sets are available for 1-phase and 3-phase power supply as well as a 3-phase rigid connection.

IEC309 plug connectors ensure reliable grounding in the rack. The power supply components are optimized for these applications and the dimensioning ensures reliable and permanent grounding. IEC320 connectors are used within the rack.

Open Infrastructure

Compliance with standards means that third-party products or products from third-party suppliers, such as electric door locks, smoke and water level sensors as well as power supply components, can likewise be integrated.

Patented Device Cabinet

This PRIMECENTER Rack is a patented device cabinet (patent specification: DE 199 62 659 C 2).

The invention deals primarily with a server cabinet. Because the mounting area with the devices and servers contained within is arranged asymmetrically, space is available left at the side for cable routing and for horizontal cable supports. Additional devices, particularly vertically aligned 19-inch modules can be arranged toward the front of this free side space.

Principle of Operation of the PRIMECENTER LC Cooling System Preface

The air circuit is closed, so no heat (thermal load) is emitted into the room.

The air which has been heated by around 40% by the servers is drawn in by the high-performance fans. Through the air duct integrated into the rear door the air flows downward to the heat exchanger. There the air is cooled (e.g. to 20o) and directed to the front of the server. The server fans can draw in the cool air and guide it over the internal equipment.

Figure 4: Air flow (seen from the side)

The temperature of the fans is controlled in accordance with the internal rack temperature. A temperature sensor continuously measures the temperature in the rack (on the side of the server feed air).

At temperatures lower than 10°C the fans rotate at a minimal speed of 30% of their maximum speed. Between 18°C and 24°C the speed increases in proportion to the temperature up to 95% of the maximum speed.

Preface Principle of Operation of the PRIMECENTER LC Cooling System

Failure of the temperature sensor or of one of the fans sets an alarm using a potential free contact.

When the rack door is opened the fans are automatically shut down.

V Caution

● PRIMECENTER LC Rack only works if cold server feed air and heated server outlet air are fully separated. Height units not in use must be sealed using dummy panels.

● When the cooling system fails the unit doors must be opened to prevent a build-up of heat in the cabinet. In this case the heat load is dissipated into the room where the unit is located.

● When the PRIMECENTER LC fans fail the unit doors must be opened to prevent a build-up of heat in the cabinet. In this case the heat load dissipated into the room where the unit is located.

● When the rear door (with fans) is opened the front door must also be opened. (However, opening the front door does not mean the rear door must be opened.)

2 Important NotesThis chapter provides you with important information on setting up and operating the PRIMECENTER LC Rack system.

2.1 Notes on Safety

V CAUTION!

Observe the safety instructions in the documentation for the individual components mounted in the rack and the following notes on safety.

● The activities described in this manual may only be performed by technicians, service personnel or technical specialists. Ignoring the instructions in this manual can result in personal injury or damage to equipment (risk of tipping over, etc.).

● Make sure the floor at the final place of installation has sufficient load-bearing capacity.

● When connecting or disconnecting cables, refer to the relevant notes in the section “Connecting and Disconnecting Cables” on page 66.

● Route the cables in such a way that they do not form a potential hazard (make sure no one can trip over them) and that they cannot be damaged.

● When mounting a server, pull the telescopic rails out all the way until they click into position.

V CAUTION!

● For safety reasons, no more than one unit must be pulled out of the rack at a time, otherwise the rack may tip over.

This is illustrated by the following pictogram:

22 PRIMECENTER LC

Notes on Safety Important Notes

● Before you mount a server in the PRIMECENTER LC Rack, remove all heavy and easily removed server components such as hot-plug disks and power supply modules for redundant power supplies since this makes the server lighter and easier to mount.

● Before pushing extended telescopic rails back into the rack, pull the ball cage of the telescopic rail forward as far as it will go.

● For safety reasons, no more than one unit may be withdrawn from the rack at any one time during installation and maintenance work. If more than one unit is withdrawn from the rack at any one time, there is a danger that the rack will tilt forward.

● If necessary, have other people help you mount the individual compo-nents in the rack because of the weight involved.

● Install only system expansions that satisfy the requirements and rules governing safety. If you install other expansions, you may damage the system or violate these safety regulations. Information can be obtained from customer service or your local sales office.

● If you cause a defect on the device by installing or exchanging system expansions, the warranty is invalidated.

● The configurations available in the PRIMECENTER LC Rack can carry a leakage current >3.5 mA. Therefore, a ground connection must be established before connecting to the mains (see chapter “Power Supply” on page 73).

● The AC power connection for the PRIMECENTER LC Rack must be installed by an authorized electrician approved by the local utility company.

PRIMECENTER LC 23

Important Notes Notes on Safety

V Caution!Risk of electric shock

IRepair and cleaning work should only be performed by qualified personnel. The personnel must ensure that the unit is electrically isolated whilst it is serviced and cleaned. You must therefore shut down the unit properly before starting work.

V Caution!Risk due to improper work on the unit

Cleaning and servicing may only be performed by qualified personnel. To ensure that the unit remains safe to use and has a long service life, it is imperative that you observe the maintenance and cleaning intervals.

V Caution!

To ensure reliable operation of the PRIMECENTER LC Rack, the correct amount of chilled water must be available at the correct temperature and pressure. The water quality must comply with VGB-R 455 P (see “Anhang B: Anforderungen an die Wasserqualität” on page 89).

V Caution

● The PRIMECENTER LC Rack only works if the cold server feed air and heated server outlet air are fully separated. Height units not in use must be sealed using dummy panels.

● When the cooling system fails the unit doors must be opened to prevent a build-up of heat in the cabinet. In this case the heat load is dissipated into the room where the unit is located.

● When the PRIMECENTER LC fans fail the unit doors must be opened to prevent a build-up of heat in the cabinet. In this case the heat load is dissipated into the room where the unit is located.

● When the rear door (with fans) is opened the front door must also be opened. (However, opening the front door does not mean the rear door must be opened.)

Notes on Mounting the Rack Components Important Notes

2.2 Notes on Mounting the Rack Components

Before you start mounting the rack components in the PRIMECENTER LC Rack, you should identify and mark the positions of the individual components in the PRIMECENTER LC Rack according to the configuration generated using the System Architect (see section “The System Architect” on page 48).

Marking and numbering the height units simplifies the assembly when installing and adding on components.

The total mounting height for the PRIMECENTER LC Rack is 31/40 height units (HU). One height unit corresponds to 44.45 mm (see section “The Height Unit (HU)” on page 48).

A lift truck is available from Fujitsu Siemens Computers to ensure that heavy components (e.g. von PRIMEPOWER Servers) can be fitted precisely into the rack. The address for ordering the lift truck is available from FSC Service.

Observe the following rules when mounting the components:

● Mount the components in the rack from bottom to top.

● Mount heavy parts at the bottom, e.g. the uninterruptible power supply.

● Mount the keyboard or rack console at a height that makes it easy to operate (HU 17 - 21).

● Position the dummy covers so that later planned extensions can be installed without having to rearrange components.

● To accommodate the ventilation concept and ensure proper ventilation of all the components in the rack, any unused areas must be closed using dummy covers.

● Mount the components in accordance with the documentation supplied.

3.7 Chilled Water Connection

This section describes how you connect the PRIMECENTER LC Rack to the chilled water network.

V Caution!

The heat exchanger can be pulled out. The chilled water pipes must be connected in such a way that the heat exchanger can be pulled out when the connection is undone.

If the heat exchanger is connected to the chilled water network using threaded fittings, the pipe socket must be supported when it is tightened.

Before the server cabinet is placed in service the pipe connections must be checked for leaks.

Quick-fitting couplings with a 1” female thread which are self-closing to prevent leakage are provided for the chilled water connection.

When the connection is made the valves in the two pipes press against each other only after the coupling has engaged and thus ensure that there is no leakage of water. When the quick-fitting coupling is opened the two pipes automatically close before they are separated. This ensures that there can be no leakage of water.

I ● If you screw the chilled water pipes and the connecting pieces together without pulling the connecting pieces out first, you must hold the connecting pieces in place when you fasten them.

● Before the server cabinet is placed in service the pipe connections must be checked for leaks.

● Carefully remove the air from the heat exchanger when you fill it.

● After an extended period without use, and in particular if there is a danger of frost, the heat exchanger and the supply pipe must be drained completely. Drain them completely by blowing them out with compressed air and remove all bleed and draining screws.

● The chilled water pipes should be insulated against condensation and energy loss using waterproof insulation. An insulation thickness of 9-12mm is recommended with a thermal conductance of 0.037 W/mK.

4 Mounting Rack ComponentsThis chapter describes how to prepare the PRIMECENTER LC Rack for the installation of rack components. Refer to the appropriate operating manuals for information on how to mount the components themselves.

The rack has three areas in which components can be mounted:

– the 19-inch area with 32/40 HU, which is accessible from the front and is used for mounting the rack components horizontally.

– the optional expansion area with 2 x 2 HU, which is accessible from the front and is used for mounting the rack components vertically.

– the 19-inch area, which is accessible from the rear and is used for mounting the rack components horizontally if not already occupied by other compo-nents.

Before you prepare the PRIMECENTER LC Rack and start mounting compo-nents, you should use the System Architect to help you determine the mounting position and the mounting height of the relevant components.

I Also observe the information in the section “Notes on Mounting the Rack Components” on page 24.

V CAUTION!

Make sure the floor at the final place of installation has sufficient load-bearing capacity!

Mounting in the front 19-inch area Mounting Rack Components

4.5 Mounting in the Front 19-inch Area

Components are mounted in the front 19-inch area of the PRIMECENTER LC Rack using either telescopic or sliding rails. Light components can also be mounted via the front panel.

If components are mounted using telescopic rails, all the cables leading to the components are routed via an articulated cable guide. If service work needs to be performed, the cables can remain connected when the components are removed from the PRIMECENTER LC Rack. This makes servicing much easier and also allows device components in hot-plug slots to be replaced during operation.

If components are mounted using sliding rails, all the cables are routed directly to the components and are connected without any special aids, i.e. without using an articulated cable guide. If service work needs to be performed, all connected cables must be disconnected before the components can be removed from the PRIMECENTER LC Rack.

A support bracket is required for mounting components regardless of whether telescopic rails or sliding rails are used.

Figure 28: Support brackets with a load capacity of 150 kg and 50 kg respectively

Support brackets with a load capacity of 50 kg (1 HU) and for support systems with a load capacity of 150 kg (2 HU) are available. A cable clip can be mounted on each support bracket for vertical cabling.

4.7 Mounting in the Rear 19-inch Area

You can mount additional rack components in the rear 19-inch area if:

– the front area is not occupied with rack components

– the rack components mounted in the front area leave enough space for additional components to be mounted at the rear (in the rear area)

An appropriate support bracket is again required for mounting rack components on the lefthand side. If you cannot use an existing bracket, you will have to mount a new support bracket at the appropriate position.

Figure 32: Example of how to mount a rack component in the 19-inch area at the back

Ê If there is no support bracket at the appropriate position on the left rear support upright, mount a support bracket with the appropriate load capacity (1) (see section “Mounting the Support Bracket” on page 57).

Ê Use the support upright (2) for mounting rack components on the righthand side.

V CAUTION!

Please pay heed to the ventilation concept. The cooling of the built-in rack components must be ensured.

Ê Pull the power plugs of all affected devices out of the sockets on the socket strip in the PRIMECENTER LC Rack.

Ê Pull all data transmission cables out of the sockets provided for the data transmission or telephone networks.

Ê Disconnect all cables on the devices.

5.3 Routing Cables

Only internal cables are routed at the factory. All other cables must be routed during rack installation.

If one or more articulated cable guides are mounted with an installed device, all external cables must be routed in these guides.

If the installed articulated cable guides are not sufficient for the number of cables, you must install additional ones.

The articulated cable guides must be installed 1 HU apart. If this is not possible, the cables must be routed in the rack before installing the device.

For easier access to the articulated cable guides you can pull out the systems above and below the guides toward the front.

This section contains several examples of how to route cables in the PRIMECENTER LC Rack.

5.3.2 Cable Routing and Strain Relief for the Built-in Rack Component

The rack component is inserted in the PRIMECENTER LC Rack and secured. The cables are attached to the relevant plug connectors and should be routed in the cable management system with a reserve length by making a loop over the center axis of the rack component (see figure 38).

When the rack components are extracted, the cables fixed in the articulated guide are also pulled out. The articulated guide stabilizes the cables at the appropriate rack component height and thus ensure a trouble-free insertion and removal (see figure 39 below and figure 40 on page 69). The mechanical attachment is performed using the strain relief fitting on the connectors.

PRIMECENTER LC 73

6 Power SupplyThe PRIMECENTER LC Rack offers various possibilities for supplying power to the integrated rack components. The connection conditions described in the relevant manuals for the integrated rack components should be complied with in all cases.

The power supply to the PRIMECENTER LC Rack can be included optionally as part of a redundancy concept. In the simplest scenario, redundancy is achieved with the 3-phase mains connection by distributing redundant power supplies to the phases. Ever higher redundancy is achieved by duplicating the current distribution components so that the PRIMECENTER LC Rack can be connected to two independent inhouse power distribution networks via a dual power feed. This option is offered both in 1-phase and 3-phase socket strips.

V CAUTION!

Remember in configurations with several mains supply cables that all cables must be disconnected so that there is no current flowing to the rack!

The power supply complies with the requirements of the EN60950 regulations. This allows a PRIMECENTER LC Rack to be connected with a flexible 3 or 5-wire cable to a rated current of up to 16 A per phase. The respective line cross-sections should be noted.

Because of the high number of current distribution components within the PRIMECENTER LC Rack, the configuration can carry leakage currents > 3.5 mA. For this reason, the PRIMECENTER LC Rack may generally only be connected to internal power distribution networks via rigid connections or via industrial connections in accordance with IEC309.

Note the requirements outlined in the data sheets when installing the power distributor.

74 PRIMECENTER LC

Connecting to the Mains Power Supply

6.1 Connecting to the Mains Using a 1-phase Socket Strip

A socket strip with ten insulated sockets and a connection cable is available for a 1-phase AC mains power connection. The cable should not be routed over sharp edges or pinched.

Power is supplied to the individual rack components via the socket strip. The load should be distributed equally to the two 5-pin elements of the 10-way socket strip.

In the case of a dual power feed to the PRIMECENTER LC Rack, ensure that redundant power supplies are distributed to socket strips that are disconnected from the mains.

The following socket strips are available:

● With 16 A IEC309-compliant connector

● With 32 A IEC309-compliant connector

● With 30 A Twist Lock connector, NEMA L6-30P

● With 16 A IEC320-compliant connector

6.2 Connecting to the Mains Using a 3-phase Socket Strip

The PRIMECENTER LC Rack provides a 3-phase AC mains power connection and thus offers a uniform power distribution to the power distribution network.

A socket strip with 3 socket blocks (one block per phase, each with one protective contact socket and four insulated sockets ) is available (figure 44).

V CAUTION!

Make sure that the current load of the individual insulated socket blocks do not exceed 10 A.

Servers with redundant power supply units can then be connected to different phases and are thus given additional phase redundancy for high availability configurations. If only one phase fails, the systems that are connected to another phase remain operational.

6.2.2 3-phase Power Distribution

Power is supplied to the individual rack components within the PRIMECENTER LC Rack via the socket strip. If the number of sockets available on the socket strip is not enough, you can use a supplementary socket strip as an extension. (see figure 44 on page 76).

The following supplementary socket strips are available:

● Socket strip with 5 sockets (one 16 A protective contact socket and four 10 A insulated sockets) and 3 m connection cable with protective contact utility connector.

● Socket strip with 3 sockets (three 10 A protective contact sockets) and 1.5 m connection cable with insulated connector (max. 10 A).

Ê If necessary, screw additional socket strips to the (left or right) rear support upright of the PRIMECENTER LC Rack. Only one supplementary socket strip per phase is permitted.

Ê Connect the socket strips as shown.

Power Supply Power Supply via UPS

6.3 Power Supply via UPS

If uninterruptible power supply (UPS) units are involved in supplying energy to the rack and its components, the connection conditions described in the relevant manuals for the integrated rack components should be complied with in all cases. There are many possible combinations:

● The rack is supplied completely via the UPS:

In this case the UPS should be connected directly to the mains. In the rack the rack components are connected directly or optionally via a socket strip to the UPS.

● The rack is partly supplied via a UPS:

This gives a choice of connecting the UPS via the socket strip in the rack or directly to the power supply network. This process also applies if a number of UPSs are used in the rack.

● High-power UPSs above 3000 VA:

UPSs above 3000 VA need their own mains connection because of the large amount of current that they draw. Both fixed connections and connections using IEC 309-complaint connectors can be used here. The technical requirements can be taken from EN60950 and from the specifications of the local utility company.

Online UPSs and line-interactive UPSs are available in different performance classes. Different UPS types are used preferentially by the various server lines for the PRIMECENTER LC Rack. Please refer here to the configuration infor-mation for the individual severs.

The power supply can be configured freely depending on the UPSs used. The input power connector of the respective UPS can be connected either directly to the mains or to the protective contact socket of the main socket strip in the rack by using the connection cable supplied with the respective UPS. The rack components or additional socket strips should be connected to the power outlets of the respective UPS.

Note that the increased leakage currents >3.5mA can also flow over UPS connection cables. The connection cables therefore have to be assigned uniquely to the device and the strain on the UPS relieved, either using appro-priate strain relief facilities or by routing with suitable cabling, which requires the assistance of tools to change the cabling.

Potential Compensating System Power Supply

6.4 Connecting to the Potential Compensating System

If required by local regulations, the PRIMECENTER LC Rack can be connected to the indoor potential-compensating system via the grounding screw located at the rear of the rack chassis. This grounding only protects from external parasitic voltages and does not replace the protective conductor in the mains feeders.

7 Servicing and MaintenanceI Servicing and maintenance work may be performed by appropriately

trained personnel only and in accordance with the applicable regulations and the manufacturer’s specifications!

Only use original spare parts that have been tested and approved by the manufacturer. (If necessary, request a comprehensive spare parts list from the manufacturer.)

For cleaning use commercially available cleaning agents only. Follow the safety measures stipulated and do not use any tools that may cause scratches or any tools for scraping (otherwise the surface protection could be destroyed).

Preparatory steps:

– Shut down the fans and any other electrical components properly and disconnect them from the power supply

– Wait until the fan blades have stopped moving

– Make sure the equipment cannot be switched on again

– Shut down the water cooling circuit and make sure it cannot be switched on again

7.1 Fan Maintenance

Cleaning fans

– Clean intake opening

– Clean fan blades

General inspection of fans

– Excessive bearing play?

– Leakage of lubricant from bearings?

– Unusual operating noises?

Replacing fans

The normal service life is approx. 40 000 operating hours at a temperature of 40°C.

I Shut down the cabinet before removing the housing cover.

Ê Remove the housing cover from the unit.

Ê Undo the fixing bolts for the fan to be replaced.

Ê Disconnect the controller circuit board cable and remove the fan.

Ê Install the new fan.

To install the fan proceed in reverse order:

Ê Dispose of the old fans properly!

PRIMECENTER LC 83

Servicing and Maintenance Cooling System Maintenance

7.2 Cooling System Maintenance

I The efficiency of heavily soiled heat exchangers is very limited, so these must be cleaned immediately.

Inspect the cooling system regularly:

– Check the heat exchanger for soiling, damage and corrosion on the air side. Clean it on the air side if necessary.

– Check that the feed and return are functioning correctly.

– Regularly check that the odour trap (external) is functioning correctly.

– The heat exchanger can be pulled out to facilitate cleaning.

– Regularly inspect the water ciruit for leaks.

– Regularly check the condensed water drain and clean it if necessary.

I Use a vacuum cleaner, compressed air or a soft brush to clean the fins. Do not bend the fins when cleaning them as this will interfere with the air flow through the unit.

PRIMECENTER LC 85

8 Dismantling and DisposalThe PRIMECENTER LC Rack may be dismantled by suitably qualified personnel only.

Preparatory steps:

Ê Correctly shut down the fans and any other electrical components and disconnect them from the power supply!

Ê Ensure they cannot be switched on again!

Ê Shut down the water cooling circuit and ensure it cannot be switched on again.

Dismantling

Ê Disconnect the unit from the external water circuit by closing the shut-off valves and drain the water circuit in the unit.

Ê Transport the unit as described in the chapter “Transport” using a lifting device with sufficient load bearing capacity.

Disposal

Ê Dispose of the air-conditioning device in accordance with the locally appli-cable disposal and safety regulations. We recommend using a specialist recycling organization.
