Initial Start Up
10. When the cubes are about the correct size, the
unit will automatically go into a "harvest" cycle.
The purge and hot gas valves will open and on air
cooled models, the fan will stop. To operate
properly, the machine must harvest a complete
sheet of cubes. The falling ice sheet must open
the curtain and the curtain must re-close
before another freeze cycle can begin.
11. After harvest, check the thickness of the ice.
The connecting ice bridge between cubes
1
should be about
8
The "dimple" in most of the cubes must not be
1
deeper than inch.
16
If needed, adjust the bridge thickness by rotating
the adjustment screw of the cube size control.
Rotate the adjustment screw 1/8 turn at a time.
Turn it clockwise to make the bridge thicker, and
counterclockwise to make the bridge thinner.
Although the machine is not designed to harvest
individual cubes, the ice should break up into
smaller groups of cubes in the bin. Bridge
thickness may be adjusted thinner to make ice
break-up easier, but the ice must fall as a sheet.
Note: Tapping a recently harvested ice sheet with
the back of a scoop should break it up.
12. Check the operation of the bin control circuit:
push the manual harvest switch down, release it
and then hold the curtain open. This simulates the
bin being full of ice and after a few seconds with
the curtain open the ice machine should switch
itself off. Release the curtain and the machine will
restart.
13. Replace the grill and close the bin door. The
ice machine is now ready for automatic operation.
