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 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] Remove the water from the potable water supply line:

1)Remove the Front Panel.

2)Move the Control Switch, on the Control Box, to the “OFF” position.

3)Wait 3 minutes.

4)Close the Potable Water Supply Line Shut-off Valve and open the Potable Water Supply Line Drain Valve.

5)Allow the line to drain by gravity.

6)Attach compressed air or carbon dioxide supply to the Potable Water Line Drain Valve.

7)Move the Control Switch to the “ICE” position.

8)Blow the potable water line out using compressed air or carbon dioxide.
