The compressor unit package contains a service valve kit and an adapter kit. The two service

valves are to be installed on the earth loop vapor and liquid connections of the compressor

unit, using the adapters to right-size to the proper earth loop line set.

Installation of the service valves will provide isolation of the earth loop system from the compressor

unit and provide easy access to the refrigerant system.

For the installation of system components requiring refrigeration connections, refer to Figure 6 for line

set sizes and the appropriate installation manual(s) following Figure 6.

After installing and nitrogen brazing the HVAC system components and compressor unit service

valves, turn the Service Valves to Full Open and pressurize the refrigeration system to 150 psig with

dry nitrogen and a trace of refrigerant. Valve off the nitrogen Tank from the HVAC system

components and check joints with a sensitive Electronic Leak Detector to ensure they are sealed.

Repair any leaks and re-test as appropriate.
