4. Harvest
The water pump de-energizes and the water inlet
valve energizes to assist harvest and refill the water
sump. The hot gas valve opens and the refrigerant gas
warms the evaporator allowing the cubes to release
from the evaporator and drop into the storage bin.
The control system automatically determines:
• Length of time the ice machine will remain in the
harvest cycle
• Whether the condenser fan motor is energized or
de-energized during the harvest cycle
At the end of the harvest cycle the ice machine will
start 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 start-
up sequence (steps 1 – 2).
