ICE MAKER MAINTENANCE & CLEANING
The ice maker should never be allowed to operate with-
out regular maintenance and cleaning. Keeping the
unit clean and maintained will keep it sanitary, extend
the life of the machine and keep energy consumption
down. Maintenance and cleaning should be performed
approximately every six months. Some water condi-
tions will dictate even more frequent cleaning of the ice
making section, just as some carpets and pets will dic-
tate more frequent cleaning of the condenser.

The Five Things to Keep Clean

• The outside of cabinet and door
• The ice storage bin
• The ice scoop
• The condenser
• The ice making system
Cleaning the Outside of Cabinet and Door
To clean the outside of the cabinet and door (including
the door gasket), wipe off spills as they occur. If any-
thing spilled dries onto the surface, wash it off with a
mild dish soap and warm water.
Cleaning/Sanitizing the Ice Storage Bin
Sanitizing the ice storage bin periodically is recom-
mended. To do this, the unit must be switched OFF
and the storage bin emptied. Then, mix a sanitizing
solution consisting of one ounce household bleach with
two gallons of hot (95°/35°C - 115°F/46°C) water.
Using a clean soft cloth, wipe down the interior of the
storage bin with the sanitizing solution (See Figure 4-1)
and pour some of the solution down the bin drain.
Rinse the interior of the storage bin with clean hot water
and allow it to air dry before restarting the unit.
NOTE: It is recommended that cleaning/sanitizing the
ice storage bin be performed immediately after the ice
making system has been cleaned. (See next page.)

Model 315I (UC Ice Maker)
Never keep anything in the ice storage bin that is
not ice. Objects such beverage containers may be
unsanitary and their labels might fall off which
could plug the drain.
Cleaning the Ice Scoop
The ice scoop should be cleaned regularly to keep it
sanitary. Clean the scoop with dish soap and warm
water, as you would any other food container.
Cleaning the Condenser
The condenser is located at the right side of the com-
pressor area, behind the kickplate and it looks similar to
the radiator on a car. To clean the condenser, follow
the directions below:
1. Remove the kickplate by extracting the two mount-
ing screws, one at each side, and pull the kickplate
down and forward.
2. With a brush attachment, vacuum the face of the
condenser off while moving the brush up and down.
(See Figure 4-2)
Do not bend the metal fins of the condenser, doing
so will restrict airflow through the condenser, pos-
sibly causing mechanical failure of the ice maker.
3. After the condenser is clean, reattach the kickplate
with the mounting screws.
