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 into the freeze
or harvest cycle, as required in the cleaning
instructions.
/////////////////////////////WARNING/////////////////////////////////
Disconnect electrical power supply to icemaker
whenever adjustment procedures are performed.

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
microswitch initiates the harvest cycle. An audible
click can be heard, but in a noisy area, look at
the cam and switch to observe the event
B. To start the FREEZING CYCLE: Slowly rotate
the shaft of the timer and switch assembly
clockwise until the actuator arm on the microswitch
initiates 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 cam. 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.
lt 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 ejecting ice into
the bin. Too much time wastes icemaking capacity,
energy and water. Adjustment of the harvest cycle
may require an adjustment of the cube size
control.
