Adjustment Of The Timer & Switch Assembly
One complete revolution of the cam on the timer
represents eight minutes. If left as factory set, four
and one-half minutes comprise the freezing cycle
portion during cam rotation, and the final three and
one-half minutes is the defrost/harvest cycle.
Rotating the shaft of the timer cam clockwise will
put the ice machine in the freeze or harvest cycle.
To adjust the timer & switch assembly:
1. Remove front panel.
2. Remove control box cover.
A. To start the HARVEST CYCLE: Slowly rotate
the shaft of the timer and switch assembly
clockwise until the actuator arm on the micro
switch begins the harvest cycle.
B. To start the FREEZING CYCLE: Slowly rotate
the shaft of the timer and switch assembly
clockwise, until the actuator arm on the micro
switch starts the freezing cycle.
C. To adjust the length of the harvest cycle:
1. Loosen the adjustment screw on the cam, and
rotate the shaft of the cam to move the top part of
the assembly. More of a gap between the high and
low portions will yield more harvest time.
2. Tighten the set screw.
3. Replace the control box cover and front panel.
It. is important that the length of the harvest cycle
allow enough time for all the ice cubes to fall from
the evaporator. Too short of a time will cause the
evaporator to freeze up and stop harvesting ice.
Too much time wastes ice making capacity, energy
and water. Adjustment of the harvest cycle may
require an adjustment of the cube size control.
Adjust Bin Ice Level
1. Locate ice level control switch.
2. Move switch to the desired position.
3. To test, wait until the ice machine is near the
end of a "harvest" cycle, if there is ice in the bin
higher than the position the ice level control is set
for, the ice machine will turn OFF at the end of the
harvest cycle. If no ice in the bin, test again as
described under, "To Test The Ice Level Setting".
Disconnect electrical
power before beginning.
