INITIAL START UP
Ice Maker:
1. Remove front panel by pulling out to unsnap.
2. Remove two screws and the control box cover.
3. Remove the evaporator cover.
4. Remove the left side service panel.
5. Check that the ON/WASH/OFF rocker switch
and the Compressor ON-OFF toggle switch are in
the OFF position, on the control box.
6. OPEN the water supply line shut off valve.
7. 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 where the
actuator arm on the microswitch drops off outer
cam into cam slot. See Timer Cam Positions.
8. Move the ON/WASH/OFF rocker switch to the
ON position.
9. Observe water fill cycle: The inlet water valve
will be open and filling the reservoir. This should
take a few minutes. Near the end of that time the
water reservoir should be draining out the reservoir
drain.
Check that the water distributors are seated at the
top of the evaporators and that water flows over all
cube cells.
Note: Some water spray from the evaporators is
normal when the machine is new. The spray wll go
away after a few cycles.
10. Check that the water cascades down over
each cube mold and into the reservoir.
11. When the reservoir is full, move the
compressor ON-OFF switch, to the ON position.
12. Check operation of the freezing cycle: Ice
forms beginning at the top of the evaporators.
Freezing time will range between 17 and 25
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 20 minutes.
13. Check the discharge pressure. To optimize the
balance between water use and ice production,
the freeze cycle discharge pressure should be 220
P.S.I. G. If needed, adjust the water regulating
valve until the freeze cycle discharge pressure is
220 P.S.I.G.
14. Check CUBE SIZE
The dimensions of the cubes are fixed by the size
and shape of the molds on the evaporator plate,
except that the thickness of the cube MAY need to
be adjusted at start up. There is only one size of
cube that is correct; adjusting the cube size control
to that size of cube will allow the ice maker to
produce ice at its most efficient size. The correct
size cubes will be fully formed at the edges; will
harvest off of the evaporators beginning with
individual cubes at the top of the evaporator, then
vertical strips for the balance; and will appear
similar to the illustration for “Correct Size Cube”.
Adjust for the correct size if needed:
Locate cube size control knob, in the front of the
control box. Rotate this knob one eighth of a turn:
Counter clockwise to produce SMALLER sized ice
cubes:
Or clockwise to produce LARGER ice cubes:
Observe size of ice cubes in the next cube harvest
and adjust again if needed, until correct the ice
cube size is achieved.
