CONNECTIONS
Manifold gauge sets must utilize low loss fittings to comply
with U.S. Government rules and regulations.
CVD condensing units with reciprocating compressors
are manufactured with a check valve in the compressor
discharge line. The check valve requires an additional
connection on the condensing unit during evacuation or
recovery procedures. Connection of a manifold gauge set
(or a hose with core depressors on both ends) between the
suction filter access port and the compressor access valve
(located between the compressor and discharge line check
valve) is required.
Make these connections:
Ice Machine Head Section CVD Condensing Unit
Receiver Service Valve Compressor Discharge Access
Valve
Low Side Access Valve Suction Filter Access Valve
High Side Access Valve
Connections must
also be made at two
points on condensing
unit for complete
refrigerant recovery.
