C. Preparing the Icemaker for Long Storage

CAUTION

1.When storing the icemaker for an extended time or in sub-freezing temperatures, follow the instructions below to prevent damage.

2.To prevent damage to the water pump seal, do not operate the icemaker with the control switch in the "WASH" position when the water tank is empty.

When the icemaker is not used for two or three days under normal conditions, it is sufficient to move the control switch to the "OFF" position. When storing the icemaker for an extended time or in sub-freezing temperatures, follow the instructions below.

1.Remove the water from the icemaker water supply line:

1)Turn off the power supply, then remove the front panel.

2)Move the control switch on the control box to the "OFF" position.

3)Close the icemaker water supply line shut-off valve, then open the icemaker water supply line drain valve.

4)Allow the line to drain by gravity.

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

6)Move the control switch to the "ICE" position.

7)Replace the front panel in its correct position, then turn on the power supply.

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

9)Close the icemaker water supply line drain valve.

2.Drain the water tank:

1)Turn off the power supply, then remove the front panel.

2)Move the control switch to the "OFF" position.

3)Remove the base cover, then disconnect one end of the pump tubing to drain the water tank. See Fig. 14. After the water tank has drained, reconnect the pump tubing.

4)Replace the base cover and the front panel in their correct positions.

5)Remove all ice from the storage bin. Clean the storage bin liner using a neutral cleaner. Rinse thoroughly after cleaning.

3.On water-cooled model, remove the water from the water-cooled condenser:

1)Make sure the power supply is off, then remove the front panel and right side panel.

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

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

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