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 line 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.

[Air-cooled and Remote Air-cooled Models]

1)Run the icemaker with the Water Supply Line Shut-off Valve closed.

2)Open the Drain Valve and blow out the water inlet line by using air pressure.

3)Turn off the power supply.

4)Remove the Front Panel.

5)Move the Flush Switch on the Control Box to the “FLUSH” position.

6)Turn on the power supply, and then drain out all water from the water line.

7)Turn off the power supply.

8)Turn off the Power Switch on the Control Box.

9)Replace the Front Panel in its correct position.

10)Close the Drain Valve.
