INITIAL START UP
1. Remove the front panels by removing screws at
the base and pulling out.
2. Remove two screws and the control box cover.
3. Check that the two switches on the control box,
the ICE-OFF-WASH rocker switch and the
COMPRESSOR ON-OFF toggle switch are in the
OFF position.
4. OPEN the water supply line shut off valve.
5. Switch the electrical power ON.
6. Inside the control box is the shaft of the timer
and the switch assembly. Rotate the shaft of the
timer and switch assembly clockwise until the cam
is lined up as shown in “Front View of Timer”.
7. Move the ICE-OFF-WASH rocker switch to the
ICE position.
8. Check the water fill cycle: For several minutes
the inlet water valve will be open and water will
flow into the reservoir. Near the end of the fill
cycle, water should be overflowing the reservoir
and draining thru the reservoir drain. If at the end
of the fill cycle the reservoir is not full, repeat step
6.
Check that the sump covers are snapped in place.
Check that the water distributors are properly
seated at the top of the evaporators, and that
water is flowing over all cube cells.
Note: Some water spray from the evaporators is
normal when the machine is new. The spray will
quit after a few cycles.
9. When the sump has filled, move the compressor
ON-OFF toggle switch, to the ON position.
10. On air cooled models the fan motors will begin
to blow warm air out the back of the machine.
Water cooled models will begin to flow warm water
out of the condenser drain.
Note: To optimize the balance between ice
production and water use, the freeze cycle
discharge pressure must be 220 P.S.I.G. Check
discharge pressure and adjust the water regulating
valve to obtain 220 P.S.I.G. discharge pressure.
11. Check operation of the freezing cycle: Ice will
begin to form from the top of the evaporators
down. After the first cycle freezing time will range
between 15 and 18 minutes. Freeze cycle time is
longer for temperatures above 70
o
F. and shorter
when temperatures are below 70
o
F. Average
complete cycle time is about 19 minutes.
