B. Maintenance

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

WARNING

1.Only qualified service technicians should service this icemaker.

2.Move the control switch to the "OFF" position and turn off the power supply before servicing. Lockout/Tagout to prevent the power supply from being turned back on inadvertently.

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 buildup.

2.Storage Bin and Scoop

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

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 aircooled models)

Check the condenser once a year, and clean the coil if required by using a brush or vacuum cleaner. More frequent cleaning may be required depending on location.

C. Preparing the Icemaker for Long Storage

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.

3)Close the icemaker water supply line shut-off valve, then open the icemaker water supply line drain valve.
