Automatic Shut-Off
7. AUTOMATIC SHUT-OFF
If the storage bin is full at the end of a
harvest cycle, the sheet of cubes fails
to clear the water curtain and holds it
open. After the water curtain is held
open for 30 seconds, the ice machine
shuts off.
The ice machine remains off until
enough ice is removed from the
storage bin to allow the sheet of
cubes to drop clear of the water
curtain. As the water curtain swings
back to the operating position, the bin
switch closes and the ice machine
restarts.
NOTE: The ice machine must remain
off for 3 minutes before it can
automatically restart.
