fan to the area below—Liebert XDO fan tray hinges down to allow access to replace or service all
electrical components.
• Internal Mounting—The Liebert XDO unit is typically suspended from the overhead building
structure by inserting field-supplied threaded rods into the internal mounting brackets.

• Refrigerant Pre-Charge—Liebert XDO units with the pre-charged refrigerant option will have
one-shot style fittings or removable couplings that contain pressurized refrigerant inside the Lie-

flexible piping kits are available in lengths of 4, 6, 8 and 10 feet (1.2, 1.8, 2.4 and 3 meters). Con-
nection style to the unit end may be straight or 90 degrees. Connection to the prefabricated piping
assembly is with a threaded coupler. For information on acquiring the correct kit for your instal-
lation, refer to DPN000780, available by calling 1-800-LIEBERT and from your local Emerson
Network Power representative.
