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.

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.
