B. Maintenance

The maintenance schedule below is a guideline. More frequent maintenance may be required depending on water quality, the icemaker's environment, and local sanitation regulations.

WARNING

1.Except as specified below, only qualified service technicians should attempt to service this icemaker.

2.Move the power switch to the "OFF" position and disconnect power before servicing.

1.Stainless Steel Exterior - Performed by Qualified Service Technician or Owner/ Manager

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 buildup.

2.Storage Bin and Scoop - Performed by Qualified Service Technician or Owner/ Manager

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

3.Air Filters (air-cooled model) - Performed by Qualified Service Technician or Owner/ Manager

Plastic mesh air filters remove dirt and 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.

4.Condenser (air-cooled and remote air-cooled models) - Performed by Qualified Service Technician

The condenser should be checked and cleaned once a year. Instructions for the service technician can be found in the Installation Manual supplied with this icemaker.

C. Preparing the Icemaker for Long Storage

Performed by Qualified Service Technician

CAUTION

1.When storing the icemaker for an extended time or in sub-freezing temperatures, follow the instructions below to prevent damage.

2.To prevent damage to the water pump seal, do not operate the icemaker with the control switch in the "WASH" position when the water tank is empty.

When the icemaker is not used for two or three days under normal conditions, it is sufficient to move the control switch to the "OFF" position. When storing the icemaker for an extended time or in sub-freezing temperatures, follow the instructions below.

1.Remove the water from the icemaker water supply line:

1)Turn off the power supply, then remove the front panel.

2)Move the control switch on the control box to the "OFF" position.
