7.0INSTALLATION CHECKLIST AND SYSTEM FILL FOR STARTUP

7.1Checklist for Proper Installation

___ 1. Liebert XDR modules are securely attached to the cabinet and aligned properly with the rack.

___ 2. Check to ensure there are no obstructions that prevent the Liebert XDR from opening.

___ 3. Piping from Liebert XDP or Liebert XDC, with isolation valves, is properly connected to each Liebert XDR module.

___ 4. Liebert XD Flex Pipe couplings to prefabricated header assembly are secure and according to specifications.

___ 5. System checked for leakage.

___ 6. Check the R-134a refrigerant charge (see the user manual for either the Liebert XDP, SL-16671 or the Liebert XDC, SL-16644; each is available on the Liebert Web site, www.liebert.com).

___ 7. Run system and verify that the Liebert XDP or Liebert XDC and the Liebert XDR modules operate properly.

___ 8. Piping is insulated.

7.2Charging with Refrigerant

The Liebert XD system must be completely installed before it is charged with refrigerant. After installation is complete, refer to the Liebert XDP or Liebert XDC user manual for instructions on charging Liebert XD modules with refrigerant and the starting of the system. The complete Liebert XD system includes all Liebert XD cooling modules, a Liebert XDC or Liebert XDP and any other con- nected equipment.
