It is also used for cooling electrical engineering operating rooms using a raised floor system. The unit is state-of-the-art and built according to recognised safety regulations. Nevertheless, improper use can present a hazard to life and limb of the user or third parties, or result in possible impairment of the system and other property. The unit should thus only be used properly and in technically sound condition. Any malfunctions which impair safety should be rectified immediately! Follow the operating instructions! Proper use also includes following the operating instructions and fulfilling the inspection and maintenance conditions. The following requirements must be met for proper use: • The air-conditioned or climate-controlled room must be equipped with a raised floor system of sufficient height. • The raised floor system must have air outlets in the form of cut-outs, air outlet grids or air outlet plates. These must have an approved free cross-section area according to the CRAC system used. • An inspection area with a minimum depth of 600 mm must be kept free in front of the unit. In order to ensure fan removal, no line systems may be installed within this area. • Line systems used for connecting the CRAC system must be fed to the side of the unit next to the free space allocated for the fan area according to the diagrams in this document. • Raised floor supports installed within the specified inspection area must be removable. Technical solutions are readily available for this purpose. • Cross braces installed between the raised floor supports in front of the unit must be removable. 1.2.8 Precautionary measures Inappropriate use may result in danger. Inappropriate use may include : - Improper use - Improper rectification of malfunctions - Operation outside the required ambient conditions - Use of replacement parts which are not authorised by Rittal GmbH & Co. KG 7 Operating and Maintenance Instructions – 1 Identification (en - 00 - 11/2008) Rittal CRAC system 1.3 Product description 1.3.1 Equipment assembly and air The Rittal CRAC system is a one-piece air-circulating climate control enclosure for stand-alone air circulation operation, and is used in server rooms. treatment functions Air-circulating climate control systems are used for feeding cooled air to the server room using a raised floor cavity. The air direction inside the unit feeds the treated air downwards. The return air taken in from the room is filtered and then cooled. The cooling process is made as the air passes through a heat exchanger installed inside the unit on an incline. Depending on the specific design, either a water/air heat exchanger or a cooling circuit evaporator is installed in the unit. An optional humidification or heating of the treated air can be made depending on the version supplied. The treated air is expelled as supply air in the raised floor. The air is conveyed by a fan installed outside of the unit housing, which is mounted in a base in the raised floor. The fan is installed as a free-running wheel with an integrated EC motor. Internal deflection and impact losses in the unit are minimised through installation in the raised floor. 1.3.2 Requirements for proper use In order to guarantee the flow of air, no objects must be placed on the top of the CRAC system. Due to the air intake, the top is not equipped with a cover. Depending on the design, the top is either open or equipped with a large-scale opening. The opening must be kept free in order to guarantee uninterrupted air flow. For this reason, objects which may accidentally fall into the unit must be removed immediately. In order to guarantee the flow of air, the raised floor must be equipped with a sufficient number of air outlet plates or other approved air outlets. Closing the raised floor completely or excessively leads to failure of the IT cooling system or an insufficient cooling output. Depending on the design, the unit must be connected to a cold water system or an outdoor condenser in order to dissipate the heat removed from the air out of the unit. 1.3.3 Terminology In this documentation, the terms coolant version (DX) and cold water version (CW) are used. In coolant versions, “DX” stands for “Direct Expansion”. This is the internationally recognised designation for units which use a direct evaporator as a heat exchanger for cooling the flow of air. In cold water versions, “CW” stands for “Cold Water”. This is the internationally recognised designation for units which use a water/air heat exchanger for cooling the flow of air. CW versions are also used for mixtures of water and anti-freeze agents. “Antifrogen N” from Clariant is a popular anti-freeze agent in Europe. Operating and Maintenance Instructions – 1 Identification (en - 00 - 11/2008) 8 Rittal CRAC system 1.3.4 Requirements for correct operation of the CRAC system Coolant version (DX) In the coolant version (DX), a coolant circuit is established with R407c coolant. The previously mentioned air cooler is a direct component of this coolant circuit. The coolant version (DX) also contains the compressor (one or more, depending on the size of the unit), electronic expansion valve, oil separator (unit-specific) and other items. In this way, only a condenser needs to be installed outside of the air-circulating climate control unit in order to guarantee the primary system function (i.e. cooling of the air flow). The condenser is used to dissipate the heat removed from the air during the cooling process from the cooling circuit. The drive output of the compressor is added to the dissipated thermal output at this point. Requirement: The condenser must always be installed outdoors or in a location where the dissipated heat can be emitted freely into the surrounding environment. If heat dissipation is impeded, then this may result in the maximum permissible condensation temperature being exceeded. The pressure of the coolant used is connected to this temperature, and is constantly monitored. If the permitted condensation pressure is exceeded, then a high-pressure pressostat switches the machine off and air-conditioning is stopped. Cold water version (CW) In the cold water version (CW), the unit is fed by an external supply system. This is made either with pumped cold water without added anti-freeze agent or with a brine mixture of water and anti-freeze agent. Requirement: The unit can only reach the cooling output that it was designed for when the water inlet temperature corresponds to the design requirements. Additionally, the flow rate of the cooling medium must reach the level for which the unit was designed. This is conditional on the availability of the required static pressure for counteracting the pressure loss in the heat exchanger. The addition of anti-freeze agent reduces the specific cooling output of the heat exchanger. The cooling output for which the unit was designed can then only be reached when the proportion of anti-freeze agent in the water of the supply medium does not exceed the limits specified in the design requirements. The system-specific data detailed above can be seen in the data sheet in the appendix. 9 Operating and Maintenance Instructions – 1 Identification (en - 00 - 11/2008) Rittal CRAC system 2 Safety Instructions The Rittal CRAC system has been developed and produced with due regard to all safety precautions.

The on-site conditions must be checked for suitability by Rittal Service prior to transportation. 3.3.4 Recommendations for positioning CRAC systems in server rooms 21 The supply of air in the raised floor must be interrupted as little as possible in order to ensure the uniform use of all air outlets. For this reason, CRAC systems should always be positioned so that they are at the front of the rack suites. Cable channels and water-carrying lines in the raised floor should not cross the air supply lengthwise in the rack suites. In order to allow an easy positioning of the unit housing on the fan base during installation, a distance of around 250 mm should be maintained between the individual units. The distance from the rear wall of the unit to the structure should be 150 mm, provided the room dimensions allow this. Further information on positioning CRAC systems and system use with raised floor heights above and below 500 mm can be requested from the IT cooling product management department at Rittal. Operating and Maintenance Instructions – 3 Installation and Commissioning (en - 00 - 11/2008) Rittal CRAC system 3.3.5 Notes on planning energyefficient system operation The following design parameters form the basis of energy-efficient operation of the CRAC system: - Use of a water-based carrier medium as coolant - Realisation of a maximised return air temperature - Operation of the server room with a maximised supply temperature - Planning of the cold water or glycosol network with a maximised inlet temperature - Use of a surface-optimised free cooling system for recooling the carrier medium without the use of a compressor - Use of the CRAC system with minimal levels of pressure in the raised floor Note: Cable channels and water-carrying lines in the raised floor should not cross the air supply from the CRAC system to the air outlet plates in the raised floor. Note: A flow speed below 3 m/s should be aimed for in the air flow between the CRAC system and air outlet plates. 3.4 Scope of delivery - After unpacking, check whether all parts are present according to the delivery order. - Check all parts for damages. Report any noticeable damages to the forwarding agent. - Compare the data on the rating plate of the CRAC system and modules with the delivery order and order documentation. - Check whether all appropriate documentation and the corresponding operating instructions have been delivered. 3.5 Siting - Site the unit so that air can be drawn in or blown out without interruptions on all connections. - Do not position temperature and humidity sensors near machines and units which emit heat or moisture. Do not subject to direct sunlight. - Ensure that there is sufficient space for maintenance and operation. The free space for maintenance in front of the unit must be at least 900 mm. A space of 600 mm must be available in front of the supporting structure for installing and removing the fan. - Ensure that the installation room is sufficiently lit. - Set up and align the fan base before installing the raised floor. Consult the constructor of the raised floor when installing the fan base in an existing raised floor system. Note: The unit feet of the fan supporting structure or bottom-mounted box are insulated against vibration and height-adjustable, and are used for damping structure-borne noise and compensating for floor irregularities. Operating and Maintenance Instructions – 3 Installation and Commissioning (en - 00 - 11/2008) 22 Rittal CRAC system 3.6 Assembly 3.6.1 Fan supporting structure or bottom-mounted box • Position the fan supporting structure or bottom-mounted box in the raised floor, adjust the feet to the height of the raised floor plus approx. 5 mm, then align the fan supporting structure horizontally. Note: As the adjustable feet are equipped with springs, the height of the fan supporting structure or bottom-mounted box is reduced due to the weight of the CRAC system. 1 2 3 Fig. 5: 1 2 3 23 Fan supporting structure Connection cable, control line and pressure hoses for fan Connections for air supply temperature sensor, humidity limiter (optional) and water sensor (optional) Water sensor (optional) Operating and Maintenance Instructions – 3 Installation and Commissioning (en - 00 - 11/2008) Rittal CRAC system 3.6.2 Unit • Remove the wooden beams from the bottom of the unit. • Set the unit onto the fan supporting structure or bottom-mounted box, then align it flush to the front of the base frame. • Align the unit using the height-adjustable feet of the fan supporting structure or bottom-mounted box. • Open the front doors. • Open the shielding plate underneath the electrical unit, then open the small lower cover plate underneath the filter (1 plate in CW version, 2 plates in DX version) using a screwdriver. • Remove the display connector and open the cover plate of the electrical unit using a screwdriver. 1 2 3 4 Fig. 6: 1 2 3 4 Covers (CW version in this example) Display connector Electric unit cover plate (transparent) Shielding plate Small cover plate Note: The unit must be secured in two places on the fan supporting structure using the pre-installed connection brackets and screws inside the unit.

The doors do not need to be dismantled when installing and commissioning the unit in server rooms or air-conditioning strips. Proceed as follows to dismantle a unit door: • Remove the sealing bungs from the four door hinges with an appropriate tool (e.g. screwdriver). • Release and open the unit door. • Loosen the hinge bolts from the four door hinges by raising them with an appropriate tool (e.g. screwdriver). Pull the bolts out of the hinge bolt holding fixture up to the catch. • Begin with the lowest door hinge. Operating and Maintenance Instructions – 3 Installation and Commissioning (en - 00 - 11/2008) 26 Rittal CRAC system Note: Support the unit door so that it will not fall as the door hinges are loosened. Work with a second person when necessary. • Remove the unit door. 3.7 Media connections Note: Installing the pumped cold water/anti-freeze connections or coolant lines and establishing other media connections may only be carried out by qualified technical specialist personnel. Depending on the delivered unit type, connections for the following media lines must be established: - Feed and return lines for pumped cold water/anti-freeze solution, coolant hot gas and coolant liquid lines - Condensate discharge - Drinking water connection for humidifier The connection dimensions of all media lines can be found in the following diagrams for information purposes. A connection drawing of the delivered unit type and size can be found in the appendix. The connections are labelled clearly with the specified designations. 3.7.1 Connecting the pumped cold water lines/anti-freeze solution lines Note: A space of at least 600 mm must be left in front of the fan within the raised floor system. In this way, the fan can be removed from the front of the unit without the need for removing the supply lines. No lines may cross the specified free space. • Water-carrying lines must be installed correctly in order to prevent damage caused by leaks. • Before connecting water-carrying lines to the unit, any stoppers must be removed from the top part of the unit. • All lines are fed from below from the raised floor space through the appropriate glands in the fan base. The rubber grommets must be left inside the base to prevent air leakages and damage to the lines. • We recommend making a flexible connection to the incoming line network using high-pressure hoses. The minimum burst pressure of the attached connection hoses must be 60 bar at a media temperature of 20 °C. When adding anti-freeze agents to the medium (e.g. “Antifrogen N” from Clariant), the hose material must be resistant to the additives in the concentration required. • The control valve attachment in the return must be made using a screw connection to allow the removal of the control valve. This applies especially to rigid piping. • In the connection line of the inlet, an assembly group comprised of the following components must be installed in the raised floor in the flow direction: - Stop valve - Dirt trap 27 Operating and Maintenance Instructions – 3 Installation and Commissioning (en - 00 - 11/2008) Rittal CRAC system - Turbine sensor (optional) - Stop valve The optional turbine sensor is required for recording the throughput water quantity. For further information, see the following line diagram. • In the connection line of the return, an assembly group comprised of the following components must be installed in the raised floor in the flow direction: - Stop valve - Extruded regulation valve - Stop valve The extruded regulation valve is required for calibration of the hydraulic network. For further information, see the following line diagram. Fig. 8: Line diagram Operating and Maintenance Instructions – 3 Installation and Commissioning (en - 00 - 11/2008) 28 Rittal CRAC system Notes on water quality Only water free from suspended matter, rust, large dirt particles and algae should be used as a water-based cooling medium. The proportion of anti-freeze agent in the cooling medium must be adjusted according to the on-site conditions in order to guarantee the frost protection of the system. An anti-freeze agent (e.g. “Antifrogen N” from Clariant) can be added up to a maximum concentration of 35 % by volume. When anti-freeze agent is not added, then a corrosion-protection agent and biocide must be added in order to prevent the corrosion of system parts (e.g. distributors or buffer stores) and restrict the build-up of algae. “Protectogen” from Clariant is one example of a corrosion-protection agent that can be added here. The dosage of all additives must be made according to the corresponding manufacturer specifications. Observe the minimum dosage requirements to guarantee the necessary corrosion protection. 3.7.2 Connecting coolant lines to an external condenser (coolant condenser) (optional) Note: A space of at least 600 mm must be left in front of the fan within the raised floor system. In this way, the fan can be removed from the front of the unit without the need for removing the supply lines. No lines may cross the specified free space. • Before connecting coolant lines to the unit, any stoppers must be removed from the top part of the unit. • Both lines are fed from below from the raised floor space through the appropriate glands in the fan base. The rubber grommets must be left inside the base to prevent air leakages and damage to the lines. Note: In order for the complete system (CRAC system and outdoor condenser) to function correctly when using coolants as a cooling medium, the coolant line system must be adjusted according to on-site conditions. A reliable return of lubricating oil contained in the coolant for compressor lubrication is important for system functionality, as is the return of coolant from the condenser after shutdown periods in winter. The following points are basic information for implementation by qualified specialist personnel. • When hot gas lines are fed horizontally, ensure that no hollow areas are present where an uncontrollable build-up of oil can occur. • Always install horizontal hot gas lines connected to the condenser with an inclination towards the condenser. • When the condenser is installed above the CRAC system (typically when a condenser is mounted on the roof), then oil transfer pumps must be installed at distances of 3 metres in the vertical hot gas line. • When the condenser is installed below the CRAC system (typically when a condenser is mounted outdoors), then a coolant collector must be installed in the liquid line. The volume of the collector must be adjusted according to the on-site conditions. 29 Operating and Maintenance Instructions – 3 Installation and Commissioning (en - 00 - 11/2008) Rittal CRAC system • When a horizontal hot gas line of more than 20 metres is used, then the CRAC system must be equipped with an oil separator. This restricts the lubrication oil and feeds it back to the compressor on the extraction side via the shortest route. Note: The retrofitting of an oil separator or coolant collector in CRAC systems may only be carried out by Rittal Service International or a specialist firm on their behalf. 3.7.3 Connecting the condensate discharge connectors and humidifier discharge connectors (humidifier = optional) Note: The special siphon with anti-kickback attachment (supplied loose) must be used to prevent condensate from being drawn back into the unit due to underpressure or pressure variations (e.g. when the unit is switched on). Note: In the direction of flow, the connection line of the humidifier discharge connector may only be combined with the connection line of the condensate discharge connector after the ball siphon. A 45° junction must be used at the junction point. Note: A space of at least 600 mm must be left in front of the fan within the raised floor system. In this way, the fan can be removed from the front of the unit without the need for removing the supply lines. No lines may cross the specified free space. • Both lines are fed from below from the raised floor space through the appropriate glands in the fan base. The rubber grommets must be left inside the base to prevent air leakages and damage to the lines. • The connection is made using standard HT piping. Humidifier discharge connectors and condensate discharge connectors have a nominal diameter of 40 mm on all unit sizes. • The supplied ball siphon must be installed as a siphon trap in the condensate discharge connector. The preferred installation point is directly underneath the piping gland through the fan base. The siphon must be kept accessible for maintenance purposes. • In the direction of flow, the connection lines of the humidifier discharge connector and condensate discharge connector must be merged into a combined discharge line after the siphon. A 45° junction must be used at the junction point. • No condensate pump is installed in the CRAC system. Therefore, the combined discharge line must lead downwards to a drainage point in the building, or the storage tank must be equipped with an external condensate transfer pump. • Drainage into the wastewater system of the building must be made without counterpressure when a condensate transfer pump is not used. Operating and Maintenance Instructions – 3 Installation and Commissioning (en - 00 - 11/2008) 30 Rittal CRAC system 3.7.4 Attaching the humidifier feed water connection (humidifier = optional) Note: The humidifier used is a steam humidifier which is supplied with drinking water from the mains water network. Depending on the water hardness and the concentration of minerals in the water, the steam cylinder of the humidifier is automatically rinsed with drinking water to reduce the remaining concentration in the cylinder. The water used for rinsing exits the humidifier through the humidifier discharge connector. Note: A space of at least 600 mm must be left in front of the fan within the raised floor system. In this way, the fan can be removed from the front of the unit without the need for removing the supply lines. No lines may cross the specified free space. • The feed line is fed from below from the raised floor space through the appropriate gland in the fan base. The rubber grommet must be left inside the base to prevent air leakages and damage to the lines. • Connection lines must be produced from materials suitable for drinking water (e.g. PP plastic, copper or stainless steel). • A shut-off valve should be installed in the connection line inside the raised floor so that maintenance work can be carried out on the humidifier. This recommendation applies especially when using multiple CRAC systems. • It must be possible to shut off the drinking water supply outside the airconditioned room in order to interrupt the water supply in the event of leakage in the piping system. • Depending on the on-site connection requirements and building characteristics, a pipe disconnector must be installed in the drinking water supply line. This disconnector shuts off the supply automatically without auxiliary power in the event of a loss of line pressure in the drinking water system. 31 Operating and Maintenance Instructions – 3 Installation and Commissioning (en - 00 - 11/2008) Rittal CRAC system 3.8 Electrical connection Note: Electrical connections may only be made by qualified, electro-technical trained personnel.

The unit maintains a constant room temperature automatically. In the event of faults, the unit emits a fault alarm automatically. In the event of serious malfunctions, the unit switches itself off automatically and also emits a fault alarm. The forwarding of the fault alarm depends on the connection to the surrounding on-site equipment. If a reserve unit is available according to the project planning, then this is switched on automatically in the event of a fault. When operating according to the energy efficiency guidelines recommended by Rittal, the reserve systems also operate permanently in normal operation. When a unit breaks down, the volumetric air flow setpoints of the operational units are automatically increased without user intervention. This maintains the total planned quantity of conditioned air despite the failure of a unit. The previous operating method must be planned and parameterised by Rittal Service International during commissioning. The reserve operation of several units requires the installation of a bus line between the Rittal CRAC systems used in a room. Note: This documentation is also included with the delivery of a separate set of operating instructions for the “Rittal pcs+” controller. These operating instructions are available on the network as a separate document. For example, the Rittal pcs+ operating instructions can be used when changing temperature setpoints. Note: Opening the unit doors as described below should only be made when the unit has to be disconnected as a matter of urgency. If the unit is operating as part of a reserve combination, then switching off the unit is interpreted as a fault. If all units used for cooling IT rooms (or more than one unit when several units are used) should be switched off, then this must be agreed upon beforehand with the IT hardware operator. 4.1 Opening the front doors Note: Opening the front door containing the controller display is necessary for accessing the main unit switch. Opening the front doors during operation is essentially possible without coming into contact with rotating parts. However, the unit should be switched off on the controller display before opening the doors. For more information, see the separate operating instructions of the “Rittal pcs+” controller. The transparent cover plate used for covering the electrical unit inside the system does not need to be removed for maintenance purposes. Please observe the following safety instructions. Operating and Maintenance Instructions – 4 Operation (en - 00 - 11/2008) 56 Rittal CRAC system Danger! Electric shock. Contact with live electrical parts may be fatal.

The level of contamination is influenced by different factors, such as: • The filtration quality of air supplied by a third-party system • The operation of a server room with overpressure or uniform pressure compared to the surrounding environment • The dust released from the clothing of IT personnel • The amount of personnel occupying the room The differential pressure of the filter inserts increases when they are subjected to dust. This pressure difference on the filter is monitored and a maintenance signal is emitted by the microprocessor controller when the limit is exceeded. The CRAC system filter inserts should be replaced as soon as possible when this signal occurs. These maintenance tasks can be made independently by the customer’s maintenance staff. The measures described below must be carried out for this purpose. Danger! Electric shock. Contact with live electrical parts may be fatal. Turn off the unit at the main switch before opening the cover plate of the electrical unit. Before switching on, ensure that it is not possible to come into contact with live electrical parts. Danger! Electric shock. Some electrical circuits in the unit and the fan electrical supply remain live for some minutes after the power supply is interrupted. Contact with these electrical parts may be fatal. Wait at least two minutes before carrying out work on or near electrical parts after switching off the unit. Danger! Electric shock. Floating contacts may remain live after the power supply is interrupted. Contact with these electrical parts may be fatal. Only handle floating contacts when you are sure that they are not live. Danger! Electric shock. MSR and safety circuits remain live after the main switch has been deactivated. Contact with these electrical parts may be fatal. Only handle MSR and safety circuits when the system has been disconnected from the power supply. Operating and Maintenance Instructions – 5 Maintenance (en - 00 - 11/2008) 64 Rittal CRAC system Danger! Fatal injuries caused by the fan impellor. Keep persons and objects away from the fan impellor. Do not remove the raised floor until the power supply is disconnected and the impellor is not moving. Shut down the fan as often as possible during maintenance work. Tie long hair back. Do not wear loose clothing. Fans start up automatically following power disruptions. Danger! Injury caused by raised floor covers springing open. Excess pressure in the raised floor may lead to the covers springing up when opened. Only open the raised floor covers when the fan is shut down. Danger! Risk of contamination with hazardous substances. Breathing in or coming into contact with the filter dust can be hazardous to health. Wear a dust mask with a P2 filter insert and protective gloves when removing the filter. Also wear the additional protective clothing prescribed by the operator when exposing the filter to hazardous substances. Danger! Risk of contamination with hazardous substances. Breathing in or coming into contact with contamination caused during normal operation of the unit can be hazardous to health. Clean the unit at regular intervals. Danger! Cut wounds, especially due to sharp edges on the heat exchanger. Put on protective gloves before beginning assembly or cleaning work. Danger! Hand injuries caused by meshing gear wheels on multi-leaf dampers. Keep hands away from exterior gear wheels. Danger! Hand injuries caused by retracting multi-leaf dampers. Keep hands away from the multi-leaf dampers. Danger! Danger of burns. Do not touch the heater, steam humidifier (and lance) and the supply lines during operation and some time after operation. 65 Operating and Maintenance Instructions – 5 Maintenance (en - 00 - 11/2008) Rittal CRAC system Caution! Risk of malfunction or damage. Do not modify the unit. Use only original spare parts. Note: Observe all regional water regulations when disposing of cleaning water. 5.4.1 Removing the cover plates inside the unit Danger! Electric shock. Contact with live electrical parts may be fatal.

Only trained electro-technical personnel and electricians may open the cover plates. 1 2 3 4 5 Fig. 27: Covers (DX version in this example) 1 2 3 4 5 Display connector Main switch Electric unit cover plate (transparent) Shielding plate Small cover plates Operating and Maintenance Instructions – 5 Maintenance (en - 00 - 11/2008) 66 Rittal CRAC system Note: Only remove the cover plates inside the unit when necessary according to the descriptions of the maintenance tasks. Otherwise, the individual plates must be left in their installation positions. The following steps must be carried out when removing the cover plates: • Remove the shielding plate under the electrical unit (Fig. 27, item 4): • To do this, push the bar on the shielding plate under the electrical unit inwards, then remove the shielding plate. • Remove the cover plates under the heat exchanger (Fig. 27, item 5): CW units have one cover plate, while DX units have two cover plates underneath the heat exchanger. • To remove the plates, open the locks with a screwdriver. • Remove the cover plate on the electrical unit (Fig. 27, item 3): The display connector (Fig. 27, item 1) must be removed first. • Loosen the mounting screws on the electrical unit with a screwdriver, then pull the cable of the display and connector through the recess in the cover plate. Reassembly is made in reverse order to the process detailed above. 67 Operating and Maintenance Instructions – 5 Maintenance (en - 00 - 11/2008) Rittal CRAC system 5.4.2 Filter replacement Note: Depending on the size of the unit, the CRAC system is equipped with one or more filter inserts. Note: Replacement of the filter inserts is either made according to the maintenance plan or when the filter monitoring system emits a fault message due to a pressure difference. Note: The transparent cover plate of the electrical unit is not removed when the filter inserts are replaced. Note: The filter inserts are pressed against the heat exchanger by the air flow and kept in place by a frame plate. The rubber clamps are used additionally for locking the inserts into the correct position, which prevents the air flow from avoiding the filter. Note: Filter inserts cannot be regenerated by washing or cleaning with compressed air. Only original, packed replacement filter cassettes may be used. The following tasks must be carried out when replacing the filter insert: • Switch off the unit on the controller display on the front of the unit (see also the separate Rittal pcs+ operating instructions). • Switch off the unit additionally on the main unit switch. • Remove the shielding plate under the electrical unit (see also the safety instructions and process description in Chapter 5.4.1, "Removing the cover plates inside the unit"). • Remove the rubber clamps by detaching the metal side hooks from the holes in the heat exchanger frame. • Remove the filter inserts. • Make a visual check of the heat exchanger membrane for contamination. Clean with a suitable vacuum cleaner, if required. • Insert the new filter inserts. • Bring the rubber clamps back into their original position and attach the metal hooks to the side holes. • Reattach the cover plate. • Switch the main unit switch back on.

Operating and Maintenance Instructions – 7 Unit Components (en - 00 - 11/2008) 82 Rittal CRAC system 7.4 Humidifier (optional) 7.4.1 Steam humidifier Properties The internal steam humidifier is a non-pressurised steam generator for direct humidification of the air supply. It operates with an electrode heating system, and is designed for use with normal drinking water. It is comprised of a console with an attached steam cylinder, connected steam lance and electronic ECCM control unit. Fig. 32: Internal steam humidifier Notes on commissioning • Open the water supply line. Note: When the CRAC system is switched on, the electric system on the humidifier is put into operation and makes a system test where all LEDs on the ECCM control unit light up consecutively. The heating circuit is switched on as soon as humidification is required. The inlet valve opens and the cylinder is filled with water. The green LED lights up as soon as the submerged electrodes heat the water. Steam is produced after approximately 5 to 10 minutes. Note: The low conductivity of soft water can result in the maximum steam output not being reached in the first hours of operation. A sufficient level of conductivity is usually reached automatically through the evaporation process. Please consult Rittal Service regarding a special steam cylinder in the event of on-site water conductivity below < 300 mS/cm. Notes on decommissioning • Close the water supply line. • Press the blowdown/information key briefly and wait 5 to 10 minutes until the steam cylinder is empty. • Set the circuit-breaker of the steam humidifier to “0” in the electrical unit. This disconnects the steam cylinder from the power supply. 83 Operating and Maintenance Instructions – 7 Unit Components (en - 00 - 11/2008) Rittal CRAC system Notes on inspection, maintenance and repairs 7.5 The steam generator is maintenance-free. In the event of a fault message, Rittal Service must carry out measures to correct the fault. A fault signal is shown on the controller display when the steam cylinder intended service life has been reached. Fault signals do not lead to an automatic deactivation of the CRAC system.
