Figure 41 Piping access points
Chilled water connections to the Liebert XDP are near the bottom of the unit. Refer to the Liebert
XDP user manual (SL-16644) for further information. Piping is routed downward from the unit to
chilled water piping under the raised floor. Connections are made using standard practices for copper
chilled water piping. Field-supplied Victaulic
®
connections may be used to simplify installation in
existing facilities. Refer to Table 75 for additional information.

* Allow 8" (204mm) clearance for filter replacement.
** To ensure ensure all refrigerant flow is filtered,
install the filter dryer assembly between the discharge
line of the Liebert XDP and the first bypass
flow controller or the first Liebert XD cooling module.
*** For each Liebert XDP unit, a separate
20-40 mesh strainer is REQUIRED in the
chilled water supply from the chilled water
source. The strainer is field-supplied and
field-installed. The maximum distance
of the strainer is 10 feet (3m) from the
Liebert XDP.
