6. Harvest
The air pump (when used) remains energized and the
harvest valve(s) remains open. The refrigerant gas warms
the evaporator causing the cubes to slide, as a sheet, off
the evaporator and into the storage bin. If the damper/
curtain does not open within 3.5 minutes in the harvest
cycle the following occurs:
• 3.5 minutes - The water inlet valve energizes until
water touches the high water level probe.
• 4 minutes - The water pump energizes.
• 6.5 to 7 minutes - The water dump valve energizes.
When the sliding sheet of cubes opens and closes within
30 seconds the bin switch terminates the harvest sequence
and returns the ice machine to the freeze sequence
(step 3 - 4).
NOTE: If bin switch does not open before 7 minutes the ice
machine will start a Thaw Cycle - Refer to “Thaw Cycle” on
page 86 for details.
Automatic Shut-Off
7. Automatic Shut-Off
When the storage bin is full at the end of a harvest
sequence, the sheet of cubes fails to clear the water
curtain/ice damper and will hold it open. After the water
curtain/ice damper is held open for 30 seconds, the ice
machine shuts off. The ice machine remains off for 3
minutes before it can automatically restart.
The ice machine remains off until enough ice has been
removed from the storage bin to allow the ice to fall clear
of the water curtain or all of the ice dampers. As the water
curtain/ice dampers swing back to the closed position, the
bin switch re-closes and the ice machine restarts (steps 1 -
2), provided the 3 minute delay period is complete.
