Designing a Liebert XD Solution

3.7 Liebert XDP/XDC Placement

The XDP/XDC may be placed in the critical space or in an adjacent equipment room. The allowable dis-

tance between the XDP/XDC and its connected cooling modules is determined by the piping design and

by the amount of coolant required. Refer to 3.9 - Liebert XD Coolant™ and 3.10 - Liebert XD Piping

System Design.

The maximum height of any of the main or connecting piping should be no more than 20 feet (6m)

above the top of the XDP/XDC unit. XD cooling modules should be placed as close to the same level as

possible. The differences in elevation between the highest and lowest cooling module in a system

should be no more than 6 feet (2m).
