3. 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.
• 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) Condenser (Except water-cooled model)
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.
4) Air Filters
Plastic mesh air filters remove dirt or dust from the air and keep the condenser from getting
clogged. As the filters get clogged, the icemaker’s performance will be reduced. Check the
filters at least twice a month. When clogged, use warm water and a neutral cleaner to wash the
filters.
