Mechanical Considerations 9 4.0 M ECHANICAL C ONSIDERATIONS 4.1 Determining Placement in the Conditioned Sp ace The Liebert XDH units should be placed am ong the cabinets that generate th e greatest amou nt of heat. If heat loads are dispersed ev enly throug hout the room, the Liebert XDH modules may be spread out accordingly.
Mechanical Considerations 10 4.2.1 Airflow Direction If the Liebert XDH is installed at the end of a row, Liebert recommends using uni-directional air dif- fusers.
Mechanical Considerations 11 Inst all Air Diffusers for Best Airflow Direction 1. Remo ve the top diffuser, Part # 186458, from its packaging. 2. Check the top diffuser’s fitting s and insertion hol.

Piping 15 5.3 Connection Met hods and Point s Refer to site specific drawings for general locati ons of the piping connect ions. For Liebert XDH con- nection locations, refer also to Figure 16 . The assembly and connection means used for piping in the Liebert XD system are the same as those used in conventional refrigera tion systems.
Piping 16 5.4 Piping Considerations —Hard-Piped Connections Refrigerant enters and exits th e Liebert XDH through connections on the top of the unit (see Figure 16 ). The supply piping for each refriger ation circuit is 1/2" OD copper pi pe. The return piping for each cir- cuit is 7/8" OD copper.
Piping 17 5.4.2 Brazing Prep arations After the holding ch arge has been v e nted, a torch can be used to remove the caps over the ends of the supply and return lines. The assembly and connection means used for piping in the Liebert XD system are similar to those used for conven tional refrigeration s ystems.

Electrical 23 6.0 E LECTRICAL The unit must be installed in accord ance with national wiri ng regulations. Refer to the unit’s serial tag for electrical requirements. Refer to Table 3 for details. 6.1 Connecting High V oltage W iring The Liebert XDH requ ires single-phase power for normal operatio n.
Electrical 24 6.2 Connecting Low V oltage W iring—Optional Low voltage connections to the Liebert XDH are availa ble only on units with the optional condensate detection feature . The low voltage connection s are on th e le ft side of the cabine t, in the rear, near the power connections (se e Figure 24 ).
