ICE THICKNESS ADJUSTMENT
WARNING: Do not adjust ice thickness probe unless all other problem causes have been
evaluated.
1. Open the hinged service door 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 five (5) 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.
CLEANING/REPLACE THE FILTER
1. Remove the filter from the cabinet panel by sliding it forward toward the front of the unit.
2. Wash the filter in a solution of warm water and a mild detergent. Do not use caustic detergents as they
may attack the aluminum filter elements.
3. Dry filter thoroughly.
4. For maximum effectiveness, reactivate the filter with an air filter coating (see Parts List, Miscellaneous
Components).
CLEANING THE CONDENSER
Air-Cooled Units.
1. Disconnect power to the unit.
2. Remove the upper right side panel.
3. Remove all dirt/foreign material built up from the condenser fins (fan side). Be careful not to damage the
fins. It is recommended that a power vacuum cleaner with a “crevice”tool attachment be used.
