VI. Preparing the Appliance for Periods of Non-Use
NOTICE
• When storing the appliance for an extended time or in sub-freezing temperatures,
follow the instructions below to prevent damage.
• To prevent damage to the water pump, do not operate the appliance with the
control switch in the "WASH" position when the water tank is empty.
When the appliance 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 appliance for
an extended time or in sub-freezing temperatures, follow the instructions below.
1. Remove the water from the icemaker water line:
1) Turn off the power supply, then remove the front panel.
2) Close the icemaker water supply line shut-off valve and open the icemaker water supply
line drain valve.
3) Allow the line to drain by gravity.
4) Attach a compressed air or carbon dioxide supply to the icemaker water supply line
drain valve.
5) Make sure at least 3 min. have elapsed since you turned off the power supply. Make
sure the control switch is in the "ICE" position. Replace the front panel in its correct
position, then turn on the power supply.
6) Blow the icemaker water supply line out using the compressed air or carbon dioxide
supply.
7) Close the icemaker water supply line drain valve.
2. Remove the water from the water tank:
1) Turn off the power supply, then remove the front panel.
2) Move the control switch to the "OFF" position.
3) Drain the water tank.
a) On KM-901M_J, remove the base cover,
then disconnect one end of the pump tubing
to drain the water tank. See Fig. 6. After the
water tank has drained, reconnect the pump
tubing.
b) On KM-1340M_J and KM-1601M_J, remove the rubber cap covering the overow
pipe in the water tank. Remove the overow pipe by turning it counterclockwise. After
the water tank has drained, replace the overow pipe and the rubber cap in their
correct positions.Note: Be sure the overow pipe o-ring is in its correct position on
the overow pipe.
4) Replace the base cover (if applicable) and front panel in their correct positions.
5) Remove all ice from the dispensing unit/ice storage bin. Clean the storage bin liner
using a neutral cleaner. Rinse thoroughly after cleaning.
