NOTE: The power button must be depressed and the water
curtain/ice dampers must be in place on the evaporator

INITIAL START-UP OR START-UP AFTER
AUTOMATIC SHUT-OFF
1. Water Purge
Before the compressor starts, the water pump and water
dump solenoid are energized to purge the ice machine of
old water. This feature ensures that the ice making cycle
starts with fresh water.
2. Refrigeration System Start-Up
Ice Machine Head Section:
The harvest valve(s), air pump(s) and liquid line solenoid
valve energize to equalize high and low side refrigeration
pressure. After 10 seconds the harvest valve(s) and air
pump(s) de-energize.
CVD Condensing Unit:
The low pressure switch closes and sends voltage to
the time delay relay. The time delay relay when closed
sends voltage to the contactor coil, which energizes the
compressor.
