3.
Harvest Cycle
The compressor continues to operate and the water pump
is de-energized. The hot gas valve energizes, allowing hot
refrigerant vapor to enter and warm the evaporator. The
water valve is also energized, aiding with harvest, as well
as filling up the sump with fresh water for a new freeze
cycle.
At the point of 2 minutes to freeze end, the board will
read the “liquid line temperature” again and calculate the
“harvest time”.
The ice falls from the cups and is directed into the bin
by the ice chute. The harvest cycle continues until the
“harvest time” has elapsed, and then the machine goes
into a new freeze cycle.

Automatic Shut-Off
When the storage bin is full, the ice will come in contact
with the bin thermostat which is located inside the bin.
The machine will stop after approximately 45 seconds of
continuous ice contact with the bin thermostat probe.
The ice machine remains off until a 3 minute delay
has elapsed and enough ice has been removed from
the storage bin to allow the ice to fall clear of the bin
thermostat probe. As the ice clears the probe, the bin
thermostat warms up to above the set value and the
machine starts another freeze cycle.
