4. FREEZE
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,
where it freezes.
After six minutes the water inlet valve
is locked out and can not add
additional water.
When sufficient ice has formed, the
water flow (not the ice) contacts the
ice thickness probes. After
approximately 7 seconds of continual
contact, a harvest cycle is initiated.
NOTE: The ice machine cannot
initiate a harvest cycle until a 6-
minute freeze lock has expired.
