ADJUSTMENT OF THE TIMER & SWITCH ASSEMBLY
One complete revolution of the cam on the timer
represents eight minutes. The first part of the
cam rotation is the end of the freezing cycle, and
the final few 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.
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.
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 ejecting ice into
the bin. Too much time wastes ice making
capacity, energy and water. Adjustment of the
harvest cycle may require an adjustment of the
cube size control.
