Part Number Preliminary 6/11 287
CONNECTIONS
Manifold gauge sets must utilize low loss fittings to
comply with U.S. Government rules and regulations.
All ICVD condensing units are manufactured with a
check valve in the compressor discharge line. The
check valve requires an additional connection on the
condensing unit during evacuation and 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 - All Models
1. Suction side of the compressor through the
suction shut-off valve or suction access valve.
2. Discharge side of the compressor through the
liquid line shut-off valve or high side access valve.
3. Receiver access valve, (both receiver service
valves on S3070C = fastest recovery time) which
evacuates the area between the check valve in
the liquid line and the liquid line solenoid valve.
4. Compressor discharge access valve
5. Suction filter access valve.
Recovery/evacuation of a QuietQube
®
remote
system requires connections at five points for
complete system recovery/evacuation. Check valves
are located in the ice machine head section and the
ICVD condensing unit. Five point requires
connections between the compressor and suction
filter access valve, receiver access valve and the
high and low side access valves on the front or rear
of the ice machine to recover and evacuate the
entire system
