WATER LEVEL CHECK
Check the water level while the ice machine is in the ice
mode and the water pump is running. The correct water
level is 1/4" (6.3 mm) to 3/8" (9.5 mm) below the top of
the standpipe a line in the water trough indicates the
correct level.
The float valve is factory-set for the proper water level. If
adjustments are necessary:
1. Verify the ice machine is level (see page 4-6).
2. Remove the siphon cap from the standpipe.
3. Place the main ON/OFF/WASH toggle switch to the
ON position, and wait until the float valve stops
adding water.
4. Adjust the water level to (1/4" to 3/8" [6.3 to 9.5 mm]
below the standpipe) the line in the water trough.
5. Loosen the two screws on the float valve bracket.
6. Raise or lower the float valve assembly as
necessary, then tighten the screws.
7. Move the main ON/OFF/ WASH toggle switch to the
OFF position. The water level in the trough will rise
above the standpipe and run down the drain.
8. Replace the siphon cap on the standpipe, and verify
water level and siphon action by repeating steps 3
through 5.
ICE BRIDGE THICKNESS CHECK
NOTE: During shipping and installation the ice thickness
probe may shift, requiring further adjustment to achieve
the rated energy efficiency and production. The ice
weight per cycle must be within the minimum and
maximum for your ice machine series. Capture and
weigh the ice from the second freeze/harvest cycle. The
target weight is the middle of the minimum and
maximum weight in the chart below.
The ice thickness probe is factory-set to maintain the ice
bridge thickness at 1/8" (3.2 mm).
1. Inspect the bridge connecting the cubes. It should
be about 1/8" (3.2 mm) thick.
2. If adjustment is necessary, turn the ice thickness
probe adjustment screw clockwise to increase
bridge thickness, or counterclockwise to decrease
bridge thickness.
NOTE: Turning the adjustment 1/3 of a turn will change
the ice thickness about 1/16" (1.5 mm).
Make sure the ice thickness probe wire and the bracket
do not restrict movement of the probe.
