Freeze Sequence
3. Prechill
The compressor runs for approximately 15 seconds,
with no water circulation, to lower the temperature of
the evaporator before the water pump is energized.
4. Freeze
Water Pump
The water pump energizes and water flows over the
evaporator. The water pump is energized throughout the
freeze cycle.
Water Inlet Valve
The water inlet valve will energize and fill the trough with
additional water once the water level sensor sits below
the low-level probe.
NOTE: This only happens with the 1st cycle. From the 2nd
cycle onward, even if low water is detected, no additional
water is supplied.
Ice Thickness Probe
The freeze cycle continues until water touches the ice
thickness sensor for 5 continuous seconds, which initiates
the harvest cycle.
