Use extreme caution and care when moving and installing this unit. ! WARNING Risk of explosive discharge. Can cause equipment damage, injury or death. Closing service valves may isolate liquid refrigerant, causing high pressure and rupture of piping. Do not close valves without follow recommended procedures for repair, maintenance and replacement of components. Installing pressure relief valves in field piping that may become isolated by service valves. NOTE This document must be used together with site specific documentation and documentation for other parts of the system (heat rejection devices and cooling modules). NOTE Before any action that could cause a disturbance in the Liebert XD system’s cooling function is begun, the facility manager MUST be informed. In addition, after the action is taken and the work is finished, the facility manager MUST be informed. Fluorinated Greenhouse Gas Requirements—European Union Stationary air conditioning, refrigeration, heat pump equipments and stationary fire protection systems in the European Community market and operating with fluorinated greenhouse gases (f-gas), such as R407C, R134a, R410A, must comply with the F-Gas Regulation: (EC) No. 842/2006 (F-gas). The regulation prohibits, among other actions, venting fluorinated greenhouse gases to the atmosphere. The F-Gas Regulation also requires operators to use use all measures that are technically feasible and do not entail disproportionate cost to prevent leakage of these gases, to test for leakage regularly and to recover f-gas during equipment service and maintenance and before disposing of equipment.

The serial tag with this information is on the top of the unit, near the rear. • Check the received materials to be sure all required assemblies and parts have been received. If you discover any external damage, report it to the shipping company and your local Liebert representative. 2.3 Parts Included With Liebert XDV • Installation manual (this document) • Liebert XDV module • Parts bag including • IEC 10 ft. (3m) power cords, 2 (60Hz only; power cords for 50Hz are attached) • 1/4 - 20 full thread 1" bolts, 4 • 1/4 inch locking hex nuts, 2 • mounting clips, 2 2.4 Installation Considerations Each Liebert XDV module is to be securely mounted either on the top of a computer cabinet or rack or above the heat-producing equipment. Mounting the Liebert XDV above the rack requires Liebert’s optional mounting kit. The units are designed to be mounted without modification on Liebert Foundation™ cabinets. Mounting clips included with the Liebert XDV permit installation on other manufacturers’ cabinets and racks. The clips also can be used with the Foundation for stronger attachment. Determine whether the Liebert XDV includes the condensate detection option (factory-installed). This option will require separate low voltage connections to a monitoring unit. To minimize the possibility of condensation, insulate all piping between the Liebert XDV and the Liebert XDP or Liebert XDC. Table 1 Application limits Input Voltage 2.4.1 Range of Return Air Conditions to Unit Minimum Maximum Dry Bulb Temp. Relative Humidity -10% +10% 60° to 100°F (16° to 38°C) 20% to 80% Room Preparation The room should be well insulated and must have a sealed vapor barrier. The vapor barrier in the ceiling and walls can be a polyethylene film. Paint on concrete walls and floors should contain either rubber or plastic. NOTE The vapor barrier is the single most important requirement for maintaining environmental control in the conditioned space. Outside or fresh air should be kept to a minimum when temperature and humidity must be tightly controlled. Outside air adds to the cooling, heating, dehumidifying and humidifying loads of the site. Doors should be properly sealed to minimize leaks and should not contain ventilation grilles. 2 General product information 3.0 GENERAL PRODUCT INFORMATION 3.1 Product/System Description The Liebert XDV cooling system is designed to be attached to the top of a computer cabinet or rack containing heat dissipating equipment. Two fans draw hot air exhausted from the equipment or from the hot aisle, pass it through a cooling coil and discharge cool air back down to the cold aisle, where the equipment's air intake is located. The Liebert XDV comes from the factory ready to draw heated air through a perforated grille on the back of the unit. The Liebert XDV is easily modified to draw hot air through the bottom of the unit, should that cooling method be better suited to your application. The complete system consists of Liebert XDV modules, Liebert XDP or Liebert XDC coolant distribution units, power and signal cabling and interconnecting piping, see Figure 3 below. A condensate detection option gives notification if any condensation occurs in the Liebert XDV.

Damage should be immediately reported to the carrier and a damage claim filed with a copy sent to Liebert or to your sales representative. If you later find any concealed damage, report it to the shipping company and your local Liebert representative. Check to be sure all required assemblies and parts have been received. The Liebert XDV is shipped in a protective carton and secured to a pallet (see Figures 5 and 6). Do not remove these protective items from the Liebert XDV before it is at the installation location. When unpacking and handling the Liebert XDV, exercise extra care to prevent damage. 3 General product information 3.3 Equipment Inspection Upon arrival of the unit, and before unpacking, verify that the labeled equipment matches the bill of lading. Carefully inspect all items for either visible or concealed damage. Damage should be immediately reported to the carrier and a damage claim filed with a copy sent to Liebert Corporation or to your sales representative. ! CAUTION Risk of sudden refrigerant discharge. Can cause loss of charge and minor injury. If the optional pre-charged option is chosen, the Liebert XDV unit is shipped with a full charge of R-134a refrigerant under pressure. Do not remove the pipe caps or plugs before the unit is ready for connection to Liebert XD Piping. Supply and return fittings on the pre-charged Liebert XDV units are one-shot connections. Do not disconnect one-shot connections after they have been connected. Disconnection will release pressurized R-134a refrigerant from the Liebert XDV. 3.3.1 Recyclable Packaging All material used to package this unit is recyclable.

If required for your application, this can be changed so that the Liebert XDV takes in heated air from the bottom. This is done more easily and safely before the unit is mounted on a computer cabinet. ! WARNING Risk of high-speed moving parts. Can cause death, injury and equipment damage. Before opening the Liebert XDV, shut the unit off and disconnect all electrical power. Wait for the Liebert XDV’s fans to stop rotating before beginning to open the unit. To change the air intake: 1. Loosen the six screws holding the grille on the rear of the Liebert XDV (see Figure 9). 2. Remove the grille and lay it aside for use later. 3. Remove the channel bracket holding the two solid metal plates to the bottom of the Liebert XDV. It is secured with two screws, one on either end. 4. Lift the two solid plates out of the bottom of the Liebert XDV. 5. Optional—replace the channel bracket, securing it with the two screws removed in Step 3. 6. Lay the perforated grille down with the screws pointing up 7. Lay the two solid plates on the grille with the screws through the matching holes of the plates. 8. Hold the grille and plates together and attach the assembly to the rear of the Liebert XDV with the screws. Figure 9 Changing the Liebert XDV’s air intake location Solid plates Grille Remove rear inlet grille, taking care not to loosen the screws. Remove screws and channel bracket from base of unit, remove solid plates. Using the screws from the rear grille, reinstall the solid plates on the exterior rear of the unit. Place rear grille in a secure area for future use. 9 Mounting the Liebert XDV 5.0 MOUNTING THE LIEBERT XDV The Liebert XDV module must be securely attached to the top of the computer cabinet or, alternatively, suspended above the cabinet. For mounting atop the computer cabinet, see 5.1 - Mounting the Liebert XDV on Top of the Cabinet; to hang the Liebert XDV above the computer cabinet, refer to 5.2 - Suspended Mounting Method. Be sure to follow all applicable codes. ! WARNING Risk of top-heavy cabinet falling. Can cause equipment damage, injury or death. A lightly loaded cabinet may become top-heavy after a Liebert XDV is mounted on it, causing the cabinet to tip over, possibly resulting in serious injury. Before beginning to place the Liebert XDV on the cabinet, ascertain whether the cabinet or rack requires additional stabilization, and secure the cabinet to the floor if necessary to prevent tipover. Always use at least two persons to mount the Liebert XDV on top of a cabinet. 5.1 Mounting the Liebert XDV on Top of the Cabinet The Liebert XDV may be installed on a computer cabinet by securing it with either the two included bolts, the two included clips or both the bolts and clips. The Liebert XDV has mounting holes below the fans that match holes in the Liebert Foundation computer system cabinet. Other cabinets may require that holes be drilled to accommodate the bolts or the clips. 5.1.1 Bolting Liebert XDV to Top of Cabinet To mount the Liebert XDV: 1. With at least one additional person, lift the Liebert XDV and set it down on top of the cabinet. The front edge of the Liebert XDV should be even with the front edge of the cabinet. See Figure 10. Figure 10 Positioning the Liebert XDV X X CORRECT Liebert XDV is flush with front edge of rack INCORRECT Liebert XDV is too far from front edge of rack INCORRECT Liebert XDV hangs over front edge of rack Computer cabinet or rack Computer cabinet or rack Computer cabinet or rack 2. If your cabinet has mounting holes matching those on the Liebert XDV, align the Liebert XDV properly and insert the bolts from the bottom of the cabinet and secure them to the factoryinstalled cage nuts (see Figure 11). Tighten the bolts. If your cabinet’s mounting holes do not match those on the Liebert XDV, drill holes as required. To prevent metal shavings and particles from falling into the equipment in the cabinet or into the Liebert XDV, use a vacuum or other method to collect them while drilling the holes. After drilling the holes, insert bolts from the bottom of the cabinet and secure them to the factoryinstalled cage nuts (see Figure 11). Tighten the bolts. If also using mounting clips in conjunction with bolting method above, see 5.1.2 - Using Supplied Clips for Mounting. 10 Mounting the Liebert XDV Figure 11 Mounting hole locations—standard mounting method Rear of Liebert XDV Front of Liebert XDV Bolt 1/4" - 20 (2 places, typ.)

If your cabinet has mounting holes in position for the clips, align the Liebert XDV properly and insert the bolts from the bottom of the cabinet and secure them with the included lock washers and nuts (see Figure 13). Tighten the nuts. If your cabinet’s mounting holes do not match the clips, drill holes as required. To preventing metal shavings and particles from falling into the equipment in the cabinet or into the Liebert XDV, use a vacuum or other method to collect them while drilling the holes. After drilling the holes, insert bolts from the bottom of the cabinet and secure them with lock washers and nuts (see Figure 13). Tighten the nuts and bolts. If also using mounting clips in conjunction with bolting method above, see 5.1.1 - Bolting Liebert XDV to Top of Cabinet. Figure 13 Mounting clip placement Liebert Foundation shown without panels for clarity. Mounting holes shown may not match all cabinets. Mounting Clip (two supplied) 12 Mounting the Liebert XDV 5.2 Suspended Mounting Method The Liebert XDV also may be mounted above the cabinet by suspending it either from overhead components or from Unistruts above the cabinets (see Figures 15 and 16). An optional kit available from Liebert will simplify mounting the Liebert XDV above the computer cabinet. Each suspended-mounting method requires that the supporting components be strong enough to support the Liebert XDV’s weight with coolant, 79 lb. (36kg). Each method also requires that the Liebert XDV’s placement above the computer cabinet meets the criteria in Figure 10. To ensure efficient cooling, a baffle or similar object must be installed between the suspended Liebert XDV and the computer cabinet (see Figure 16). The baffle’s purpose is to prevent the Liebert XDV from drawing in the cooled air that it has just discharged.

The height of the Unistruts above the computer cabinet must be adequate to accommodate the combined height of the Liebert XDV and the baffle. To suspend the Liebert XDV from a Unistrut system: 1. Bolt the hangers to each corner of the Liebert XDV, inserting the Liebert-supplied bolts into factory-fabricated holes in the bottom of the Liebert XDV. See Figure 15. 2. Tighten all bolts firmly, taking care not to overtighten the bolts. 3. Using a lifting mechanism, raise the Liebert XDV with brackets attached, to the proper height and bolt the brackets to the Unistruts. Figure 15 Suspending Liebert XDV from Unistruts Bolt 3/8" -16; nut and washer provided in kit Unistrut (field-supplied) Bolt a bracket to each corner of the Liebert XDV 5.2.2 Suspending the Liebert XDV from Overhead Structures To suspend the Liebert XDV from the overhead structure using the optional overhead mounting kit and field-supplied all-thread bolts: 1. Bolt the hangers to each corner of the Liebert XDV, inserting the Liebert-supplied bolts into factory-fabricated holes in the bottom of the Liebert XDV. 2. Tighten all bolts firmly, taking care not to overtighten the bolts. 3. Install the field-supplied all-thread bolts into the overhead structure, securing them to components so they will match the layout of the brackets 4. Using a lifting mechanism, raise the Liebert XDV inserting the all-thread bolts through the bolt holes in the brackets 5. Install field-supplied nuts and washers, on the all-thread bolts, placing them on the bolts at the level desired for hanging the Liebert XDV. 6. Again using field-supplied nuts and washers, secure the Liebert XDV to the all-thread bolts. 7. Tighten the nuts until the Liebert XDV is level and well-secured. 14 Mounting the Liebert XDV Figure 16 Suspending Liebert XDV from the overhead structure 3/8"-16 all-thread bolts, field-supplied, typical Hanging Liebert XDV unit To prevent bypass air from recirculating through the Liebert XDV without it passing through the cabinet, this space between the hanging XDV and the cabinet must be blocked. 15 Mounting the Liebert XDV 5.3 Mounting Liebert XDVs in Stacked Setup Liebert designed the Liebert XDV to permit mounting the units in a stacked arrangement to increase the system’s heat-removal. Stacking may be done either during the original system or added later to an existing configuration. Stacking Liebert XDVs is possible when suspending units from either Unistruts or from the overhead structure. Hanger brackets are available in two lengths to ease hanging Liebert XDVs in a stacked arrangement. The upper Liebert XDV must be positioned forward of the front of its companion Liebert XDV for efficient heat removal (see Figure 17). Figure 17 Stacking configuration offset Hanging brackets suspend stacked Liebert XDVs from either Unistruts or from roof structure Rear of Liebert XDVs Upper Liebert XDV must line up with front edge of lower Liebert XDV Lower Liebert XDV must line up with front edge of the cabinet (space between Liebert XDV and cabinet must be blocked to prevent recirculation of cooled air FRONT OF CABINET 16 For details on preventing recirculation, see Figure 16. Mounting the Liebert XDV 5.3.1 Hanging Stacked Liebert XDVs from Unistruts Because the upper Liebert XDV in a stacked arrangement must be positioned farther forward than the lower Liebert XDV, two sets of Unistruts are required. The second set of Unistruts must be installed 9-7/8 inches (251mm) forward of the first set. This arrangement positions the stacked Liebert XDVs so that they meet the air-intake criteria shown in Figure 10 and Figure 17. After installing the Unistruts at the proper location, hang the Liebert XDVs as outlined in 5.2.1 Suspending the Liebert XDV from Unistruts. Figure 18 Attach hanger brackets to Liebert XDV for stacked arrangement Attach hanger brackets to each corner of each Liebert XDV. This arrangement permits mounting from either Unistruts or from overhead structure. 10 - 32 x 5/8" length; factory-supplied 1/4 - 20 x 5/8" length typical, 2; factory-supplied 10 - 32 x 5/8" length typical, 3; factory-supplied Figure 19 Stacked Liebert XDVs suspended from Unistruts Unistrut field-supplied upper Liebert XDV: 1 lower Liebert XDV: 2 Bolt 3/8"- 16, nut and washer factory-supplied 17 Mounting the Liebert XDV 5.3.2 Hanging Stacked Liebert XDVs from the Overhead Structure Because the upper Liebert XDV in a stacked arrangement must be positioned farther forward than the lower Liebert XDV, the place where the hangers attach to the overhead structure must be offset accordingly. The second row of attachment locations must be 9-7/8 inches (251mm) forward of the first row of hanger mounting locations. This arrangement positions the stacked Liebert XDVs so that they meet the air-intake criteria shown in Figure 10 and Figure 17. After determining the proper for attachment to the overhead structure, hang the Liebert XDVs as outlined in 5.2.2 - Suspending the Liebert XDV from Overhead Structures. Figure 20 Stacked Liebert XDVs ready for suspension from overhead structure 3/8"-16 All-thread bolts, field-supplied (four required per Liebert XDV) 18 Piping 6.0 PIPING 6.1 European Union Fluorinated Greenhouse Gas Requirements Stationary air conditioning, refrigeration, heat pump equipments and stationary fire protection systems in the European Community market and operating with fluorinated greenhouse gases (f-gas), such as R407C, R134a, R410A, must comply with the F-Gas Regulation: (EC) No. 842/2006 (F-gas). The regulation prohibits, among other actions, venting fluorinated greenhouse gases to the atmosphere. The F-Gas Regulation requires operators to use use all measures that are technically feasible and do not entail disproportionate cost to prevent leakage of these gases, to test for leakage regularly and to recover f-gas before disposing of equipment, as well as during service and maintenance. Refer to the full regulation for additional details. 6.2 System Connection Configuration If possible, connect the Liebert XDV modules to Liebert XDPs or Liebert XDCs in an interlaced configuration (see Figure 21). In an interlaced configuration, half the cooling units in an aisle are connected to one Liebert XDP or Liebert XDC and the other half in that aisle are connected to another Liebert XDP or Liebert XDC. Such interlaced piping will keep half the Liebert XDV units operating and maintain even cooling in the conditioned space should one of the Liebert XDP or Liebert XDC units fail. However, in a system with just one Liebert XDP or Liebert XDC, connect Liebert XDV modules in a non-interlaced configuration (see Figure 22). Figure 21 Typical Liebert XDV piping—interlaced connections TOP VIEW—NOT TO SCALE Liebert XDV A Liebert XDV B Liebert XDV A Liebert XDV B Liebert XDV B Liebert XDV A Liebert XDV B Liebert XDV A Liebert XDP/Liebert Supply A Return A Return B Supply B Liebert XDP/Liebert NOTE: Line size does NOT indicate pipe size difference. 19 Piping Figure 22 Typical Liebert XDV piping—non-interlaced connection TOP VIEW—NOT TO SCALE Return Supply Liebert XDP/LieLiebert XDV A 6.2.1 Liebert XDV A Liebert XDV A Liebert XDV A Piping Connections to Liebert XDP or Liebert XDC Refer to site specific drawings for general locations of the piping connections.

During brazing, the lines must be filled with flowing dry nitrogen to prevent excessive oxidation and scale formation inside the piping. Prevailing good refrigeration practices must be employed for piping supports, leak testing, dehydration and charging. Failure to use good system practices may result in damage to the system. Refer to the ASHRAE refrigeration handbook for general good-practice refrigeration piping. 6.5 Recommended Piping Size NOTICE To minimize the amount of refrigerant required, do NOT oversize the piping. Connect the main pipes between the Liebert XDV branch piping and the Liebert XDP or Liebert XDC according to Table 4. Elbows and restrictions must be minimized to ensure good fluid flow. Please see Table 4 below for recommended pipe sizes and Figure 3 for piping segment locations. 23 Piping Table 4 Branch piping sizes for refrigerant loop Pipe Function Size / Equivalent Pipe Length Liebert XDP/Liebert XDC supply line, from Liebert XDP/Liebert XDC supply to farthest Liebert XDV Liebert XDP/Liebert XDC return line, from farthest Liebert XDV to Liebert XDP/Liebert XDC return From Liebert XDV supply to supply line of Liebert XDP/Liebert XDC From Liebert XDV return to return line of Liebert XDP/Liebert XDC 6.6 1-1/8" OD (1.025" ID) for lengths up to 60 feet (18m) 1-3/8" OD (1.265" ID) for lengths over 60 but less than 175 feet (18 to 53m) 2-1/8" OD (1.985" ID) for lengths up to 60 feet (18m) 2-5/8" OD (2.465" ID) for lengths over 60 but less than 175 feet (18 to 53m) 1/2" OD (0.430" ID) for lengths up to 6 feet (1.8m) 5/8" OD (0.545" ID) for lengths over 6 feet but less than 35 feet (1.8-10.6m) 5/8" OD (0.545" ID) for lengths up to 6 feet (1.8m) 7/8" OD (0.785" ID) for lengths over 6 feet but less than 35 feet (1.8-10.6m) Connection Methods—One-Shot Connections The assembly and connection means used for piping in the Liebert XD system are the same as those used in conventional refrigeration systems. Observe all standard practices during installation and startup to prevent damage and contamination. Both supply and return fittings may be supplied with optional, one-shot connections. These fittings contain pressurized R-134a refrigerant inside the Liebert XDV. ! CAUTION Risk of sudden refrigerant discharge. Can cause injury and loss of charge. If the optional pre-charged option is chosen, the Liebert XDV unit is shipped with a full charge of R-134a refrigerant under pressure. Do not remove the pipe caps or plugs before the unit is ready for connection to Liebert XD Piping. Supply and return fittings on the pre-charged Liebert XDV units are one-shot connections. Do not disconnect one-shot connections after they have been connected. Disconnection will release pressurized R-134a refrigerant from the Liebert XDV. If the unit includes the optional, factory-installed, one-shot style connections, proceed with 6.7 - Field Installation of Liebert Flex Pipe Kit on Liebert XDV and see Figure 26. If the unit does not include flex piping, refer to 6.4.1 - Holding Charge—Hard-Piped Units.
