INITAL START UP
9. Check operation of the freezing cycle: The
compressor is operating.The icemaking process
begins; feeling the metal parts of the evaporator
plate reveals cold temperature, very shortly ice
begins to form. Tubing will become frosted at the
top of the evaporator plate. Freezing time will
range between 12 and 15 minutes. Longer time for
temperatures above 70 degrees F. and shorter
time required whentemperatures are below
70-degrees F. Average complete cycle time is
about 14 minutes.
10. Check Cube Size
There is exactly enough water available in the
reservoir to make one full sized batch of cubes.
The water pump may pick up some air at the end
of the freezing cycle: this is normal. If the water
pump runs out of water before the end of freeze,
the cube size control may be set too cold, or the
water system may be leaking water.
To produce SMALLER sized ice cube:
Locate cube size control knob, in the front of the
control box. Rotate one eighth of a turn
COUNTER Clockwise. Observe size of the ice in
the next ice cube harvest and adjust in one eighth
turn or less increments, until correct ice cube is
achieved.

Clockwise. Observe size of ice cubes in the next
cube harvest and adjust in one eighth turn or less
increments, until correct ice cube size is achieved.
11. Bin Ice Level Control Operation: With the
icemaker in the harvest cycle, place something
directly below the transducer socket. The machine
should switch off at the END OF THE HARVEST
CYCLE. Within seconds after removal of the
obstruction, the icemaker will restart. This control
has four postions, full, three quarters, one half, and
one quarter. It will not fill up closer than 8" from the
bottom of the ice machine, and will not work on
bins taller than 8'. Note: Even when full the unit will
make one batch of ice when the ICE/OFF/WASH
switch is moved from ICE to OFF to ICE.
12. Replace control box cover and all cabinet
panels and screws.
13. Explain to the owner/user the significant details
of the icemaker; start up, operation, and the
cleaning instructions. Answer all questions about
