B. Maintenance

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

WARNING

• Only qualifi ed service technicians should service this icemaker.

• Move the control switch to the “OFF” position, then unplug the appliance from the
electrical outlet before servicing.

1. Stainless Steel Exterior

To prevent corrosion, wipe the exterior occasionally with a clean, 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 storage bin.

• Clean the scoop and the storage bin liner using a neutral cleaner. Rinse thoroughly after
cleaning.

3. Air Filters (air-cooled model only)

Plastic mesh air fi lters remove dirt and dust from the air, and keep the condenser from
getting clogged. As the fi lters get clogged, the icemaker’s performance will be reduced.
Check the fi lters at least twice a month. When clogged, use warm water and a neutral
cleaner to wash the fi lters.

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.
