Notice
After opening suction, discharge and
receiver service valves, refrigerant
pressure will not be detected until the
ice machine starts a freeze cycle and the
solenoid valves energize.
Step 5 Leak-Check the Refrigeration
System.
A. Connect power to the ice machine
head section - Do not connect
power to the CVD condensing unit.
B. Press the power switch and
energize the ice machine for
60 seconds to equalize pressures.
C. Disconnect power to the ice
machine head section.
D. Leak-check line set connections,
S trap and all factory joints in head
section and condensing unit.
E. Connect power to the CVD
condensing unit and allow system
to pump down.
Step 6 Insulation Requirements.
• To prevent condensation, the entire
suction line, including the shutoff valve,
must be insulated.
• All insulation must be airtight and sealed
at both ends.
• The following insulation requirements
prevent condensation at 90° F (32°C)
ambient temperature and 90% relative
humidity. If higher humidity is expected,
increase insulation thickness:
