Installation 2 2.0 I NST ALLATION 2.1 References This document must be used together with site specific documenta tion and documentation fo r other parts of the system. 2.2 Pre-Inst allation Checks • Verify that the Liebert XDV vo ltage matches the av ailable utility power.
General produ ct information 3 3.0 G ENERAL PRODUCT INFORMATION 3.1 Product / System Description The Liebert XDV cooling system is designed to be a ttached to the top of a co mputer cabinet or rack containing heat dissipating equipment.
General produ ct information 4 3.3 Equipment Inspection Upon arrival of the unit, and before unpacking, veri fy that the labeled equi pment matches the bill of lading.
General produ ct information 5 3.3.2 Unit Handling If possible, tran sport the unit using a forklift or pallet jack. • If using a forklift or pallet ja ck, ensure that the fork tine length is suitable to safely move the packaged unit.
General produ ct information 6 Export Packaging 1. Unbend all metal tabs as indicated in Step 1 in Figure 6 . 2. Remove outer packaging when re ady to install the Liebert XDV. 3. Ke ep the Liebert XDV covered by th e unit bag until removal from pallet.
General produ ct information 7 Removing the Liebert XDV from the Pallet 1. Unfold the unit bag to expose the Liebert XDV. 2. Verify the nameplate information found on the Liebert XDV against the bi ll of lading. If the information does not matc h the product specifi ed, contact your local Liebert sales representative.
Mechanical Considerations 8 4.0 M ECHANICAL C ONSIDERATIONS 4.1 Determining Placement in the Conditioned Sp ace Liebert XDVs should be placed above or on top of the cabinets that generate the greatest amount of heat. If heat loads are dispersed ev enly throug hout the room, the Lieb ert XDV modules may be spread out accordingly.
Mechanical Considerations 9 4.2 Changing the Air Intake Location The Liebert XDV comes from the fact ory with the air intake on the re ar of the unit. If required for your application, this can be changed so th at th e Liebert XDV takes in heated air from the bottom.
Mounting the Liebert XDV 10 5.0 M OUNTING THE L IEBERT XDV The Liebert XDV module must be securely attached to the top of the computer cabinet or, alterna- tively, suspended above the cabinet.
Mounting the Liebert XDV 11 Figure 1 1 Mounting hole locat ions—st andard mounting me thod Figure 12 Mounting hole locations—alte rnate mounting point s Fan tray removed to show mounting location(s) of 1/4" - 20 bolts Bolt 1/4" - 20 (2 places, typ.
Mounting the Liebert XDV 12 5.1.2 Using Supplied Clip s for Mounting 1. Attach the mounting clips to the back of the Liebert X DV by fitting them into the machined slots.
Mounting the Liebert XDV 13 5.2 Suspended Mounting Method The Liebert XDV also may be mounted abo ve the cabi net by suspending it either from overhead com- ponents or from Unistruts above the cabinets (see Figures 15 and 16 ). An optional kit availa ble from Liebert will simplify mounting the Li ebert XDV above the computer cabinet.
Mounting the Liebert XDV 14 5.2.1 Suspending the Liebert XDV from Unistrut s The Liebert XDV may be bolted to customer-supplie d Unistruts. The hei ght of the Unistruts above the computer cabinet must be adeq uate to accommodate the combined height of the Liebert XDV and the baffle.
Mounting the Liebert XDV 15 Figure 16 Suspending Liebert XDV f rom the overhead structure 3/8 " -16 all-thread bolts, field-supplied, typical 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.
Mounting the Liebert XDV 16 5.3 Mounting Liebert XDVs in St acked Setup Liebert designe d the Liebert X DV to permit mounti ng t he units in a stacked ar rangement to increase the system’s heat-removal. Stackin g may be done eith er during the original system or added later to an existing configuration.
Mounting the Liebert XDV 17 5.3.1 Hanging S t acked Liebert XDVs from Unistrut s Because the upper Liebert XDV in a stacked arrang ement must be positioned farther forward than the lower Liebert XDV, two sets of Unistruts are required. The second set of Unis truts must be installed 9-7/8 in ches (251mm) forward of the first set.
Mounting the Liebert XDV 18 5.3.2 Hanging S t acked Liebert XDVs from the Overhead Structure Because the upper Liebert XDV in a stacked arrang ement must be positioned farther forward than the lower Liebert XDV, the place wh ere the hangers attach to the ov erhead structure must be offset accordingly.

Piping 22 6.4 Hard Piped Connection Sizes Supply piping connection is 1/2" OD copper pipe and return pipi ng connection is 5/8" OD copper. 6.4.1 Holding Charge—Hard-Piped Unit s The Liebert XDV in hard-piped configuration is shipped with a low-pressure holding charge (about 30 psi) of nitrogen to prevent oxidation and moisture.
Piping 23 Figure 25 Schrader valve location for venting holding cha rge 6.4.2 Brazing Prep arations—Hard-Piped Unit s After the holding charge for a hard-piped Liebert XDV has been vented, a torch ca n be used to remove the caps over the ends of the supply and return li nes.
Piping 24 6.6 Connection Methods—O ne-Shot Connections The assembly and connection means used for piping in the Liebert XD system are the same as those used in conventional refrigera tion systems. Observe all standard practices during installa tion and startup to prevent damage and contamination.
Piping 25 6.6.1 Refrigerant Charge—Pre-Charged Option Liebert XDVs with the pre-charged option are equipped with one-shot connections on the supply and return fittings. These contain a ch arge of R-134a refrigerant un der pressure within the unit. This charge must not be vented.
Piping 26 6.9 Connecting a Liebert XDV wi th Liebert Flex Pipe to an Operational Liebert XD System NOTICE Before connecting the Liebert XDV with Liebert Fl ex Pipe to the prefabri cated piping mains, check the whole sy stem for leaks. Check the Liebert XDV to ensure that the unit has no refrigerant leaks.
Piping 27 Figure 29 Deta il view of Liebert XD Fl ex Pipe and prefabricated pipin g port 8. Repeat Steps 6 and 7 for the smaller coupler (supply line). 9. Once the supply and return co nnections are completed, check to make sure the Lieb ert XDV fan power switches are Off, then connect the power cords to their power sources.
Piping 28 6.10 Disconnecting a Liebert XD V With Liebert Flex Pipe From a Liebert XD System NOTICE Before uninstalling a Liebert XDV with Liebert Flex Pipe fr om the pre fabricated piping mains: With the fans running, close the supply serv ice valve, wait approximately two minutes, then clos e the return service valve.
