Installation

7.If a leak is located, use proper procedures to remove the refrigerant/nitrogen mixture, break the connection and remake as a new joint. Retest for leaks after making repairs.

8.Open the liquid line service valve and the compressor discharge service valve.

Chilled Water Piping

Evaporator water inlet and outlet types, sizes and locations are shown in Figure 9 to Figure 14. Refer to the operating GPM parameters listed in Figure 21 when determining flow and piping requirements. Figure 22 illustrates the typical water piping components for chiller applications. Refer to this illustration while following the discussion on the various piping components.

Isolate the water pumps from the system to avoid vibration transmission. To minimize heat gain and prevent condensation, insulate all water piping. Use an appropriate pipe sealant on all threaded connections.
