Piping

3.4.2Piping Mains

All refrigeration piping mains connected to the Liebert XD cooling module, both supply and return, should be installed with a downward pitch toward the Liebert XDP of 1-2" for every 20 feet (25.4-51mm per 6m) of pipe run.

Install a 20-40 mesh strainer on the chilled water supply to the Liebert XDP. The strainer is required to prevent particles in the chilled water from entering the Liebert XDP’s heat exchanger. The maximum distance from the strainer to the Liebert XDP is 10 feet (3m).

NOTICE

Risk of particles in chilled water. Can cause equipment damage and reduced cooling.

Failure to install a strainer in the supply line to the Liebert XDP can result in damage to the unit’s heat exchanger.

3.4.3Bypass Flow Controller

Three bypass flow controllers are required to ensure that the Liebert XDP pumps operate within the optimum range. These devices are added to the field piping and simulate the flow of additional cooling modules.

Each bypass flow controller must be installed with one shutoff valve to allow the controller to be disabled when cooling modules are added to a Liebert XD system.

Bypass flow controllers should be connected between the main supply and the main return lines of the field piping. The connection points to the main supply and return lines should be in a convenient and accessible location between the Liebert XDP/Liebert XDC and the first Liebert XD module in the circuit. See Figures 20 and 21 for piping details of the bypass flow controller.

Refer to Table 5 to determine the number of bypass flow controllers that must be open to provide proper refrigerant flow based on the total nominal cooling capacity of the cooling modules in each Liebert XD system.
