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.
