Automatic Shut-Off
Ice Machine Head Section: When the storage bin is full
at the end of a harvest sequence, the sheet of cubes
fails to clear either one or both water curtains. After one
or both water curtains are held open for 7 seconds the
ice machine shuts off.
CVD Condensing Unit: When the refrigerant pressure
is low enough to open the low-pressure switch, the
contactor coil is de-energized and the compressor and
condenser fan motor stop.
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(s). As the water curtain(s) swing
back to the operating position, the bin switch re-closes
and the ice machine restarts (steps 1 - 2) provided the 3
minute delay period is complete. Both curtains must be
closed to start an ice making sequence.
