Freeze Sequence

The compressor is on for 30 seconds (60 seconds
initial cycle) prior to water flow, to prechill the
evaporator.

4. Freeze
The water pump restarts after the prechill. An even
flow of water is directed across the evaporator and into
each cube cell, where it freezes. The water fill valve
will cycle on and then off one more time to refill the
water trough.
When sufficient ice has formed, the water flow (not the
ice) contacts the ice thickness probe. After
approximately 10 seconds of continual water contact,
the harvest sequence is initiated. The ice machine
cannot initiate a harvest sequence until a 6 minute
freeze lock has been surpassed.
