Compressor units are shipped from the factory with a low pressure nitrogen holding charge.
Carefully relieve the holding charge when the compressor unit is being prepared to connect
refrigerant system piping.
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.
The service valve configuration provided is illustrated in Figure 4a. The ball valve stem is
accessed by removing the cap. The service port is equipped with a Schrader valve insert.
Figure 4a. Service Valve Orientation
Complete service valve installation instructions are contained in the
Service Valve Kit Installation
Manual
, included with the service valves.
