IMPORTANT SAFETY GUIDELINES
SAVE THESE INSTRUCTIONS
CAUTION
!
Risk of piping and component rupture. May cause injury or equipment damage.
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.
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.

2.0 GENERAL PRODUCT INFORMATION
The Liebert XDCF™ is a self-contained module designed to cool Egenera’s BladeFrame EX cabinets
and equipment without exhausting heat into the room.
Liebert XDCF modules consist of a sheet-metal frame, coil and filter dryer. It has no moving parts
and needs no electricity.
The Liebert XDCF system consists of:
• Liebert XDCF modules—upper and lower models are available
• Liebert XD Flex Pipe (optional)—connects Liebert XDCF units to supply and return piping (ships
with Liebert XDCF)
• Liebert XD Piping—delivers R-134a refrigerant through flexible piping
• Liebert XDP or Liebert XDC—supplies R-134a refrigerant to Liebert XDCF modules
(see Liebert XDP or Liebert XDC user manual for required chiller or drycooler)
Liebert XDCF modules attach to the rear of the Egenera BladeFrame EX
the BladeFrame cabinet is exhausted through the Liebert XDCF, which absorbs the heat. The cooled
air passes into the room and the heat is carried away by the Liebert XDCF’s R-134a refrigerant.

2.3 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.

2.4 Product/System Description
Upper and lower modules may be mounted on the rear of the Egenera BladeFrame. Each module,
when attached to a fully loaded BladeFrame EX rack, has a nominal cooling capacity of
10kW (2.8 tons; 34,000 BTUh). Performance is based on:
• Entering fluid temperature—55°F (12.8°C) and
• Dew point—50°F (10°C) or lower.
The complete system consists of Liebert XDCF modules, piping and Liebert XDP or Liebert XDC (see
Figure 3 below.

2.5 Equipment Inspection
Upon arrival of the unit, and before unpacking it, verify that the labeled equipment matches the bill
of lading. 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.
Each Liebert XDCF 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 attached to an Egenera BladeFrame
and ready for connection to Liebert XD Piping.
Supply and return fittings on the Liebert XDCF 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 XDCF.
2.5.1 Unit Handling
When unpacking and handling the unit, exercise extra care to prevent damage.
If multiple Liebert XDCF units are delivered, they will be shipped on a pallet. A pallet jack will be
required to move these units to the installation location. When using a pallet jack, ensure that it has
the size and length needed for safe handling of the pallet.

2.6 Unpacking the Liebert XDCF
The unit is shipped in a protective package. Do not remove the packaging from the Liebert XDCF
before it is at the installation location.
• When unpacking and handling the Liebert XDCF, care should be taken to prevent damaging the
coils.
• Remove outer packaging when ready to install the Liebert XDCF.
• Do not use unit piping to lift or move the Liebert XDCF.
2.6.1 Recyclable Packaging
All material used to package this unit is recyclable. Please save for future use or
dispose of the material appropriately.
CAUTION
!
Risk of sharp edges, splinters and exposed fasteners! Can cause personal injury!
Only properly trained personnel wearing appropriate safety headgear, gloves, shoes and
glasses should attempt to move, lift, remove packaging from, or prepare unit for installation.
NOTICE
Risk of unit damage if improperly stored. Keep the unit indoors and protected from dampness,
freezing temperatures and contact damage.
