FREEZE SEQUENCE
3. Prechill
The compressor lowers the temperature of the
evaporator(s) before the water pump is energized. The
water fill valve will energize and remain on until water
completes the water level probe circuit.
4. Freeze
The water pump energizes and water flows over the
evaporator. After water contacts the water level probe
the water fill valve de-energizes. The control board will
automatically cycle the water fill valve. The valve energizes
once in the pre-chill and up to twice in the freeze cycle.
The freeze cycle continues until the six minute freeze lock
expires and enough ice has formed to send a signal from
the ice thickness probe to the control board.
Water Pump
The water pump(s) energizes and water flows over the
evaporator. The water pump is energized throughout the
freeze cycle.
