Performed by Qualified Service Technician
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.

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.
5) Open the water regulating valve by using a screwdriver
to pry up on the spring retainer underneath the spring.
While holding the valve open, blow out the condenser
using the compressed air or carbon dioxide supply until
water stops coming out.
