118 Part Number Preliminary 6/11
Freeze Sequence
3. Prechill
The compressor is on for 30 seconds (60 seconds
initial cycle) prior to water flow, to prechill the
evaporator. The water fill valve is also energized and
will remain on until water completes the water level
probe circuit.
4. Freeze
The water pump(s) 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 on and off as
needed during the first six minutes of 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.
