7. Preparing the Icemaker for Long Storage

IMPORTANT

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, using air or carbon dioxide, to prevent damage to the water supply line at sub-freezing temperatures. 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 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. See Fig. 1.

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

8)Allow the line to drain by gravity.

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

10)Blow the water-cooled condenser out using compressed air or carbon dioxide until water stops coming out.

[2]Remove the water from the potable water supply line:

1)Remove the front panel. (Except water-cooled model)

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. See Fig. 1.
