INITIAL START UP
10. Check Cube Size
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.
To produce LARGER ice cube:
Locate cube size control on the front of the control
box Rotate the adjusting knob one eighth of a turn
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. Check harvest time. The machine will have
to harvest all of the cubes before it goes back
into the freeze cycle.
Increase the Harvest Time if there is less than 15
seconds of harvest time after the last cube has
fallen into the bin.
Decrease the Harvest Time if there is much more
than 15 seconds of harvest time after the last cube
has fallen into the bin. Note: Harvest time is
dependent upon the water and air temperatures at
the ice machine. Colder air and water will result in
faster ice making, but longer harvest cycles. Do
NOT adjust harvest time too short, as this will
cause a freeze up of the evaporators.
To Adjust Harvest Time:
A. Disconnect electrical power.
B. Locate timer cam in the control box.
C. Loosen set screw holding the two halves of the
cam together, and rotate the front half to increase
or decrease the harvest portion of the cam (low
part).
D. Re-tighten the set screw.
E. Reconnect power and check the cube size after
the next cycle (cube size may need adjustment).
12. Replace control box cover and all cabinet
panels and screws.
13. Check operation of the bin control by holding
ice on the bin control tube in the bin. The machine
should shut off at the end of the harvest cycle.
14. Thoroughly explain to the owner/user the
significant specifications of the icemaker, the start
up and operation, going through the procedures in
the cleaning instructions. Answer all questions
about the icemaker by the owner; and inform the
owner of the name and telephone number of the
local authorized SCOTSMAN Distributor, or
service agency.

When the cubes are the correct size,
they will be connected together
vertically, and drop off in strips.
The batch weight per cycle should be
about 5.5 lb.
