INITIAL START UP
Before Start Up:
1. Check that the Master ON-OFF switch and the
Compressor ON-OFF switch are in the OFF
position.
2. Switch on the electrical power. Electrical power
must be supplied to the ice machine for 4 hours
before starting the compressor for the first time.
The crankcase heater will now warm up the
compressor’s oil. The oil is warmed to evaporate
any refrigerant that may have collected in it. If
there is refrigerant in the oil when the compressor
starts, the oil will foam and will not lubricate the
compressor properly, shortening its life.
Do not start the compressor for the first time
unless the dome of the compressor is warm.
Start Up:
1. Remove front panel by removing screws at the
base and pulling out.
2. Remove two screws and the control box cover.
3. OPEN the water supply line shut off valve.
4. Open the “king” valve on the receiver.
5. Inside the control box is the shaft of the timer
and the switch assembly. Rotate the shaft of the
timer and switch assembly clockwise to start the
timer. The timer starts when the actuator arm on
the microswitch drops off outer cam into cam slot.
See “Front View of Timer”.
6. Move the Master ON-OFF switch to the ON
position.
7. Allow the reservoir to fill. If needed, rotate the
timer clockwise a to begin another "harvest" cycle
to add more water to the reservoir.
Note: Some water will drip off the evaporators, this
is normal and there will be a reduction in water
dripping after several cycles of ice.
8. When the sump has filled, move the compressor
ON-OFF toggle switch, to the ON position.
9. Check operation of the freezing cycle: As the
icemaking process begins; feeling the metal parts
of the evaporator plate reveals cold temperature,
very shortly ice begins to form. Tubing will become
frosted at the top of the evaporator plate. Freezing
time will range between 15 and 18 minutes.
Longer time for temperatures above 70 degrees F.
and shorter time required when temperatures are
below 70-degrees F. Average complete cycle time
is about 18 minutes.
