2. MAINTENANCE

IMPORTANT

This icemaker must be maintained individually, referring to the instruction manual
and labels provided with the icemaker.

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) Storage Bin and Scoop

• Wash your hands before removing ice.  Use the plastic scoop provided (Accessory).

• The Storage Bin is for ice use only.  Do not store anything else in the bin.

• Keep the scoop clean.  Clean it by using a neutral cleaner and rinse thoroughly.

• Clean the bin liner by using a neutral cleaner.  Rinse thoroughly after cleaning.

3) Air Filter (Air-cooled model only)

A plastic mesh air filter removes dirt or dust from the air, and keeps the Condenser from
getting clogged.  As the filter gets clogged, the icemaker’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.

4) Condenser (Air-cooled model only)

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
icemaker.
