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

below.

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.
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.
!
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.
