C. Preparing the Icemaker for Long Storage
CAUTION
When storing the icemaker for an extended time or in sub-freezing
temperatures, follow the instructions below to prevent damage.
When the icemaker is not used for two or three days under normal conditions, it is
sufficient to only move the power switch to the "OFF" position. When storing the

1) Turn off the power supply, then remove the front panel.
2) Move the power switch 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, then move the power switch to the "ON"
position. Replace the front panel in its correct position, then turn on the power supply.
7) Blow the icemaker water line out using the compressed air or carbon dioxide supply.
8) Close the icemaker water supply line drain valve.
2. Drain the evaporator:
1) Turn off the power supply, then remove the front panel.
2) Move the control switch to the "DRAIN" position, then replace the front panel in its
