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 (bin 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 Filters (air-cooled models only)

The plastic mesh air filters located behind the louvers 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 they are clogged, use warm water and a neutral cleaner to wash the filters.

4. Condenser (air-cooled and remote air-cooled models 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 or condenser unit.

C. Preparing the Icemaker for Long Storage

WARNING

When shutting off the icemaker for an extended time, drain out all water from the water tank and remove the ice from the storage bin. The storage bin should be cleaned and dried. Drain the icemaker to prevent damage to the water supply line at subfreezing temperatures, using air or carbon dioxide. Shut off the icemaker until the proper ambient temperature is resumed.

When the icemaker is not used for two or three days, it is sufficient to only move the control switch to the "OFF" position, unless the icemaker will be at subfreezing temperatures.

1.On water-cooled model only, first remove the water from the water-cooled condenser:

1)Remove the front panel.

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

3)Wait 3 minutes.

4)Move the control switch to the "ICE" position.

5)Allow 5 minutes for the icemaker to fill with water and the water pump to start operating.

6)Close the water-cooled condenser water supply line shut-off valve.

7)Open the drain valve for the water-cooled condenser water supply line.

8)Allow the line to drain by gravity.

9)Quickly attach compressed air or carbon dioxide supply to the condenser water line drain valve.
