Notes On Operation
1. The electric eyes signal the ice machine to shut
off whenever the bin becomes full. After the eyes
sense that there is ice between them, the ice
machine will shut off at the end of the next harvest
cycle. This last harvest cycle will be longer than the
rest, and will be for the Maximum Harvest Time.
Note: Ice will normally fill up to the bottom of the
evaporators before the machine shuts off.
2. After the bin has filled the ice machine will not
be able to restart for 4 minutes. However, if
needed, the Freeze button may be pushed and the
unit will restart.
For example: If ice is removed from the bin
immediately after the machine has filled up and
shut off, the machine will not restart for 4 minutes.
3. If the bin controls sense a bin full signal before
any water is used (float stem up), the machine will
shut off on bin full.
If there was a problem during Initial Start Up:
If an error light came on, check the following.
1. Water error.
A water error could have been determined by the
AutoIQ Controller if the inlet water valve does not
fill the reservoir, or if the water pump does not start
and lower the water level.
2. Refrigeration error.
A refrigeration error could have been determined
by the AutoIQ Controller if the water temperature
did not drop during the freeze cycle. The controller
will next check the compressor discharge
temperature. If the discharge temperature is too
low, the refrigerant error light will be switched on,
and the machine will Shut Down.
Resets:
Note: The machine may be reset and restarted by
pushing and releasing the Off push button switch,
and then pushing and releasing the freeze push
button switch.
Water Cooled: If the water to the water cooled
condenser circuit is cut off during a freeze cycle,
the high pressure cut out will stop the operation of
the compressor. The control is an automatic reset,
but if the water interruption is prolonged, the
AutoIQ Controller will shut the machine down when
maximum freeze time has been exceeded.
