CONNECTIONS
Recovery/evacuation
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 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.
Manitowoc recommends using an access
NOTE:
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.
