2. OPERATION - How it works
Water flows from the potable water source through the Water Supply Line Shut-off Valve,
entersattheWaterInletfittingandintotheWaterReservoir. TheWaterReservoirfunctions
to maintain a constant water level inside the Freezer Assembly. Water from the Water
ReservoirentersatthebottomoftheFreezer. Heatisremovedbytherefrigerationprocess
and ice forms inside the Freezer.
A stainless steel Auger, located inside the Freezer, is direct-driven by the Gear Motor, and
the rotating Auger carries the ice upward to the end of the Auger, where excess water is
pressed out of the ice, as the ice is extruded and broken into cubelet ice (compressed ice)
and then pushed out into the Storage Bin.
Moving the Power Switch on the bottom left of the Middle Front Panel, to the “ON” position
startsthe automatic and continuousicemakingprocess. When the Ice StorageBinis filled
with ice, the Bin Control Switch will shut off the icemaking process. As the ice is removed
fromtheStorageBin,theBinControlSwitchresetsautomaticallyandrestartstheicemaking
process.

1) Stainless Steel Exterior
To prevent corrosion, wipe the exterior occasionally with a clean and soft cloth. Use
a damp cloth containing a neutral cleaner to wipe off oil or dirt build up.
2) Air Filter - See Fig. 7
Aplasticmeshairfilterremovesdirtordustfromtheair,andkeepstheCondenserfrom
getting clogged. As the filter gets clogged, the ice dispenser’s performance will be
reduced. Check the filter at least twice a month. When clogged, use warm water and
a neutral cleaner to wash the filter.
3) Condenser
Check the Condenser once a year, and clean if required by using a brush or vacuum
cleaner. More frequent cleaning may be required depending on the location of the ice
dispenser.
