CONNECTIONS
Notice
Recovery/evacuation of a remote system requires
connections at four points for complete system
evacuation.
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
liquid line solenoid.
• Access (Schrader) 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.
NOTE: Manitowoc recommends using an access valve core
removal and installation tool on the discharge line quick-
connect fitting. This permits access valve core removal.
This allows for faster evacuation and charging, without
removing the manifold gauge hose.
