VIII. REFRIGERANT SERVICE PORTS

Each unit has 3 service ports: one on the suction line, one on
the liquid line, and one on the compressor discharge line. Be
sure caps on the ports are tight.

IX. HIGH FLOW VALVES

Located on the compressor hot gas and suction tubes are
High Flow Valves. Large black plastic caps distinguish these
valves with O-rings located inside the caps. These valves can
not be accessed for service in the field. Ensure the plastic
caps are in place and tight or the possibility of refrigerant
leakage could occur.
