CONNECTIONS
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 (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.
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.
