2. Refrigeration System Start-Up
Ice Machine Head Section: The liquid line solenoid
valve and water inlet valve energize. Five seconds
later single and twin evaporator models de-energize
the harvest valve(s) and air compressor (when used).
CVD Condensing Unit:
When the refrigerant pressure is high enough to close
the low-pressure control the contactor coil energizes
and the compressor starts.
The compressor and fan cycling control* are supplied
with power throughout the entire Freeze and Harvest
Sequences. When the refrigerant pressure is high
enough to close the fan cycling pressure control the
condenser fan motor starts.
*The IB0680C & S0680C ice machines do not use a
fan cycling control. The compressor and the
condenser fan motor are wired through the contactor.
Any time the contactor coil is energized, these
components are supplied with power.
