ADJUSTMENTS
Adjustment Of The Timer & Switch Assembly
One complete revolution of the cam on the timer
takes eight minutes. The normal setting is three
and a half minutes, as set at the factory.
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 a corresponding adjustment of the
cube size control. Rotating the shaft of the timer
cam clockwise will allow putting the machine into
either the freezing cycle or harvest cycle, as
required in the cleaning instructions.
Electrcial power present
in the control box can
cause personal injury.
Disconnect power
before begining to
adjust timer.

To Adjust The Timer & Switch Assembly:
The length of the harvest cycle can be changed by
loosening the set screw on the cam, and then
rotating the shaft so that the opening between the
cams change. More of an opening between the
cams = more harvest time. The harvest time may
be reduced if not needed. This will yield more ice
per day.
