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

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
