VI. CLEANING AND MAINTENANCE INSTRUCTIONS

IMPORTANT

Ensure all components, fasteners and thumbscrews are securely in place after any maintenance or cleaning is done to the equipment.

1. 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 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 tem- peratures.

[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.
