4. Harvest Cycle
The condenser fan motor and water pump de-energize.
The water fill valve energizes to purge the water in the
water trough. The hot gas valve also energizes at the
beginning of the harvest cycle to divert hot refrigerant gas
into the evaporator. The hot refrigerant gas warms the
evaporator, causing the cubes to slide, as a sheet, off the
evaporator and into the ice storage bin.
The control system automatically determines the length
of the harvest cycle, based on the temperature of the
refrigeration system liquid line at the end of the freeze
cycle. At the end of the harvest cycle, the ice machine
returns to another freeze cycle (step 3).
5. Automatic Shut-off
The level of ice in the ice storage bin controls the ice
machine shut-off. When the bin is full, ice cubes contact
the bin thermostat bulb holder, which cools down and
opens to stop the ice machine. The ice machine remains
off until enough ice has been removed from the bin. This
causes the thermostat bulb holder to warm and close,
restarting the ice machine.
When the ice machine restarts, it returns to the startup
sequence (steps 1 – 2).
