B. Maintenance Instructions

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, 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 (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 (self-contained air-cooled models)

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 (self-contained and remote air-cooled 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

IMPORTANT

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 sub-freezing 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 sub-freezing temperatures.

1. On water-cooled models only, first remove the water from the water-cooled

condenser:

1)Turn off the power supply and remove the front panel and right side panel.

2)Close the condenser water supply line shut-off valve. If connected to a closed loop water supply, also close the condenser return outlet shut-off valve.

3)Open the condenser water supply line drain valve. If connected to a closed loop water supply, also open the condenser return outlet drain valve.

4)Attach a compressed air or carbon dioxide supply to the condenser water supply line drain valve.
