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.
Control Board Timers
The control board has the following non-adjustable
timers:
• The ice machine is locked into the freeze cycle for
6 minutes before a harvest cycle can be initiated.
This can be overridden by initiating a manual
harvest. Refer to "Manual Harvest" on page 65
• The maximum freeze time is 60 minutes at which
time the control board automatically initiates a
harvest sequence.
• The maximum harvest time is 3.5 minutes. The
control board automatically initiates a freeze
sequence when these times are exceeded.
• The maximum water fill is 6 minutes.
