or death.

The XDV is top-heavy. 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.

Refer to the full regulation for additional details.

This document must be used together with site specific documentation and documentation for other
parts of the system.

2.2 Pre-Installation Checks

• Verify that the Liebert XDV voltage matches the available utility power. 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.

Installation

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.

2.4.1 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.

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.

3.2 Checking and Unpacking

When the Liebert XDV is delivered, 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 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.

3.3 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.

4.0 MECHANICAL CONSIDERATIONS

4.1 Determining Placement in the Conditioned Space

Liebert XDVs should be placed above or on top of the cabinets that generate the greatest amount of
heat. If heat loads are dispersed evenly throughout the room, the Liebert XDV modules may be
spread out accordingly.

The Liebert XDV is engineered to fit atop computer enclosure cabinets. Figure 8, below, illustrates
the unit’s dimensions and the location of pipes, the fan tray and power connections. (An optional kit is
available to permit suspending the Liebert XDV from either Unistruts or from the overhead struc­ture; see 5.2 - Suspended Mounting Method.).

4.2 Changing the Air Intake Location

The Liebert XDV comes from the factory with the air intake on the rear of the unit. 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.

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.

Mounting the Liebert XDV

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.

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 Sup-
plied Clips for Mounting.

5.1.2 Using Supplied Clips for Mounting

1. Attach the mounting clips to the back of the Liebert XDV by fitting them into the machined slots.
Tighten the bolts.

2. 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 Lie-
bert XDV to Top of Cabinet.

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.

5.2.1 Suspending the Liebert XDV from Unistruts

The Liebert XDV may be bolted to customer-supplied Unistruts. 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.

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.

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).

5.3.1 Hanging Stacked Liebert XDVs from Unistruts

A
t

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.

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.

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).

6.3 Connection Methods and Points

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. All piping must be ASTM Type "L" copper pipe.

For hard-piped Liebert XDVs, the supply piping connection is 1/2" OD copper pipe, and the return
piping connection is 5/8" OD copper. For Liebert XDVs with the pre-charged option, both supply and
return fittings are one-shot connections. These fittings contain pressurized R-134a refrigerant inside
the Liebert XDV.

Supply piping connection is 1/2" OD copper pipe and return piping connection is 5/8" OD copper.

6.4.1 Holding Charge—Hard-Piped Units

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. This must be vented before removing the caps on the
ends of the supply and return piping.

To vent the holding charge:

1. Find the Schrader valve that contains the nitrogen holding charge in the Liebert XDV (see
Figure 24).

2. Vent the holding charge by depressing the pin in the valve.

3. Replace and secure the cap on the Schrader valve.

6.4.2 Brazing Preparations—Hard-Piped Units

After the holding charge for a hard-piped Liebert XDV has been vented, a torch can be used to remove
the caps over the ends of the supply and return lines.

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.

6.6 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.

9.0 OPERATION

The Liebert XDV’s fan controls are on the front of the unit, near the fans, for easy access. Each switch
controls the operation of one fan (see Figure 36). The separate switches permit the use of only one
fan at a time, reducing the airflow if the Liebert XDV’s full cooling capacity is not needed.

The Liebert XDV’s primary and secondary circuit breakers are also on the front of the unit. They are
at the top left when facing the Liebert XDV (see Figure 36).

NOTE

One of the Liebert XDV’s fans must be turned on before either the Liebert XDP or Liebert XDC
is switched on.

One of the Liebert XDV’s fans must be operating at all times that the Liebert XDP or Liebert
XDC is operating. Operating either the Liebert XDP or the Liebert XDC without at least one of
the Liebert XDV’s fans rotating may cause a system malfunction.

10.0 MAINTENANCE

Minimal maintenance is required to keep the Liebert XDV operating at optimal levels. The unit
should be cleaned and checked for damage and worn parts. Suggested maintenance includes:

• Cooling fins—Clean any dust and debris from the cooling fins, taking care not to bend them

• Circulating fans—Clean any dust from the fans.

10.1 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 during equipment service and maintenance and before disposing of equipment.

Refer to the full regulation for additional details.
