6.4Hard Piped Connection Sizes

Supply piping connection is 1/2" OD copper pipe and return piping connection is 5/8" OD copper.

6.4.1Holding Charge—Hard-Piped Units

The Liebert XDV in hard-piped configuration is shipped with a low-pressure holding charge (about 30 psi) of nitrogen to prevent oxidation and moisture. This must be vented before removing the caps on the ends of the supply and return piping.

To vent the holding charge:

1.Find the Schrader valve that contains the nitrogen holding charge in the Liebert XDV (see Figure 24).

2.Vent the holding charge by depressing the pin in the valve.

3.Replace and secure the cap on the Schrader valve.
