Model UC-15I (Undercounter Ice Machine)
ADJUSTMENTS
There are two settings that may be adjusted:
• Cube Weight
• Bin Ice Level
Cube Weight Check and Adjustment
The cube weight can be increased
from the factory setting by adjusting the freeze cycle fin-
ish time.
To check for additional finish time
1. Press and hold the POWER button for five (5) sec-
onds.
2. Count the flashes on the ICE light. The light will
flash once for each additional minute of freeze
cycle time.
To adjusting finishing time
1. Press and hold the POWER button.
2. Press and release the CLEAN button once for each
additional minute of freeze cycle time desired.
3. Adjust in one (1) minute increments and allow the
ice machine to run several freeze/harvest cycles,
then inspect the ice cubes. If a heavier cube
weight is desired add another minute of freeze time
by repeating the process.
NOTE: Five minutes is the maximum additional fin-
ish time that can be added. Pressing the CLEAN
button 6 times will reset the finishing time to zero
(0) additional minutes.
Testing and Adjusting Bin Thermostat
The bin thermostat stops ice production when the bin is
full, with ice touching the bin thermostat tube.
Figure 4-20)
The thermostat is functioning correctly if, when three ice
cubes are placed on the thermostat tube for 5 minutes,
the ice machine stops. The ice machine should restart
5 minutes after the cubes are removed.
If ice production stops before the bin is full or continues
after bin is full, the bin thermostat can be adjusted as
follows (See Figure 4-21):
1. Extract four bolts holding kickplate and pull it for-
ward.
2. Turn thermostat adjustment screw counterclockwise
to decrease the level of ice; turn clockwise to
increase the level of ice.
3. Reassemble the kickplate.
