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 hold it open.
• Ice contacts the bin level thermostat probe (when
used).
• Ice damper is held down.
After the water curtain or ice damper are held open for
30 seconds, the ice machine shuts off. The ice
machine remains off for 3 minutes before it can
automatically restart.
CVD Condensing Unit: The liquid line solenoid valve
closes, allowing the refrigeration system to pump
down. When the refrigerant pressure is low enough to
open the fan cycling pressure control the condenser
fan motor stops. When the refrigerant pressure is low
enough to open the low pressure control, the contactor
coil is de-energized and the compressor stops.
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 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 3 minute delay
period is complete.
* All CVD0675 and early production CVD0685
condensing units were manufactured without a fan
cycle control and will not energize and de-energize the
fan motor. Current production CVD0685 are
manufactured with a fan cycle control.
Energized Control Board Lights-
Single Evaporators = No Lights
Twin Evaporators = Depending on which water curtain
is open, the closed bin light will be lit (green)
Quad Evaporators = Depending on which damper is
open, the closed dampers will be lit (green)
