AUTOMATIC SHUT-OFF
7. Automatic Shut-Off
Ice Machine Section: Shuts off when:
• The storage bin is full at the end of a harvest sequence.
• The sheet of cubes fails to clear the water curtain and
holds it open.
• One or both ice dampers are held down.
• Bin level probe thermistor senses setpoint (when
used).
After the water curtain or ice damper are held open for
30 seconds, the ice machine shuts off. The ice machine
control board starts a 10 minute delay which must time
out before the ice machine can automatically restart.
CVD Condensing Unit: The liquid line solenoid valve closes
and the condensing unit pumps down. The LPCO opens,
starts a five minute delay period and de-energizes the
contactor coil, which de-energizes the compressor and
condenser fan motor.
RESTART AFTER AUTOMATIC SHUT-OFF
The ice machine remains off until enough ice has been
removed to allow the ice to fall clear of the water curtain
or ice damper. As the water curtain or ice damper swings
back to the operating position, the bin switch re-closes
and the ice machine restarts (steps 1 - 2), provided the
10 minute control board delay period and 5 minute
condensing unit delay periods have completed.
