MAINTENANCE/ADJUSTMENT PROCEDURES
THERMOSTAT ALTITUDE ADJUSTMENTS
IMPORTANT: Adjust the bin thermostat setting only if storage hopper over fill is a problem.
BIN THERMOSTAT
1. Open the hinged service door.
2. The adjustment screw is located below the " Flush"switch on the left side of the electrical box.
3. For altitudes up to 6,000 feet, turn the adjustment screw COUNTERCLOCKWISE as follows:
ELEVATION (FEET)
4. For altitudes above 6,000 feet, consult the factory.
ICE THICKNESS ADJUSTMENT
WARNING: Do not adjust ice thickness probe unless all other problem causes have been
evaluated.
1. Open the hinged service door on the upper left side panel and remove the ice drop and hopper covers.
2. Collect and weigh the ice produced during the harvest cycle. The amount of ice harvested should weigh
approximately 3 pounds. Use the following procedure to adjust the probe to obtain this weight. (A clockwise
adjustment will reduce the harvest weight while counterclockwise turns will increase the amount.)
CAUTION: Do not turn the screw on the end of the probe. Rotate the plastic probe body
only using a 3/8 inch open end wrench. Make adjustments in 1/8 inch turn increments.
A.
Place the " Stop/Run"switch in the " Stop"position. (If unit is in the ice making cycle, stop the unit at
the end of the harvest cycle).
B.
Access to the probe is obtained by removing the rear service panel. (For units without beverage fau-
cets, the probe can be adjusted from the front by removing the lower front panel if rear access is
blocked).
C.
Adjust the probe.
D.
Place the " Stop/Run"switch in the " Run"position.
E.
Collect and weigh the ice harvested. Repeat step A through E as necessary to obtain the required
amount of ice.
3. In making an initial adjustment (for example, if the probe has been removed and replaced for any reason),
turn probe clockwise until it just touches the evaporator coil (a slight back pressure will be felt). Turn probe
counterclockwise 2-1/2 turns. Follow procedure in step 2 to obtain the required ice harvest weight.
