4.5Liebert XDCF Installation Considerations

No cutting or drilling is required to attach the modules to the rear of the Egenera BladeFrame cabi- net. All mounting holes, slots and pins required are fabricated at the factory.

Liebert XDCF modules attach beside the power modules on the rear of the Egenera BladeFrame (see Figure 41).

4.6Liebert XDCF Piping Connection Methods and Points

The assembly and connection means used for piping in the Liebert XD system are the same as those used in conventional refrigeration systems. Observe all standard practices during installation and startup to prevent damage and contamination.

Supply piping connection is 1/2" OD copper pipe, and return piping connection is 5/8" OD copper. Both supply and return fittings are one-shot connections. These fittings contain pressurized R-134a refrig- erant inside the Liebert XDCF.

! WARNING

Risk of explosive discharge. Can cause death, injury and equipment damage.

Do not disconnect one-shot connections after they have been connected. Disconnection will release pressurized R-134a refrigerant from the Liebert XDCF.

The Liebert XDCF has supply and return piping access on the top of each module.
