Section 5
Water System Ice Making Sequence of Operation
NOTE: The sequence of operation is the same for
self-contained and remote models.
INITIAL START-UP OR
START-UP AFTER AUTOMATIC SHUT-OFF
1. Before the ice machine starts, the water pump and
water dump solenoid are energized for 45 seconds
to purge old water from the water trough. This
ensures that the ice-making cycle starts with fresh
water.
FREEZE CYCLE
2. To pre-chill the evaporator, there is no water flow
over the evaporator for the first 30 seconds of the
freeze cycle.
3. The water pump starts after the 30-second pre-
chill. An even flow of water is directed across the
evaporator and into each cube cell.
