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 5 for line
set sizes and the appropriate installation manual(s) following Figure 5.

Earth Loop Specification and Installation Manual
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 and bubble solution to ensure
they are sealed. Repair any leaks and re-test as appropriate.
