NORMAL REMOTE MODEL PROCEDURES
Refrigerant Recovery/Evacuation
Do not purge refrigerant to the atmosphere. Capture
refrigerant using recovery equipment. Follow the
manufacturer’s recommendations.
CONNECTIONS
Make these connections:
• Suction side of the compressor through the suction
service valve.
• Discharge side of the compressor through the
discharge service valve.
• Receiver outlet service valve, which evacuates the
area between the check valve in the liquid line and
the pump down solenoid.
• Access (Schraeder) valve on the discharge line
quick-connect fitting, located on the outside of the
compressor/evaporator compartment. This
connection evacuates the condenser. Without it,
the magnetic check valves would close when the
pressure drops during evacuation, preventing
complete evacuation of the condenser.
