Removal from Service/Winterization
GENERAL
Special precautions must be taken if the ice machine is
to be removed from service for an extended period of
time or exposed to ambient temperatures of 32°F
(0°C) or below.
If water is allowed to remain in the ice machine in
freezing temperatures, severe damage to some
components could result. Damage of this nature is
not covered by the warranty.
Follow the applicable procedure below.

SELF-CONTAINED AIR-COOLED ICE MACHINES

1. Disconnect the electric power at the circuit breaker
or the electric service switch.
2. Turn off the water supply.
3. Remove the water from the water trough.
4. Disconnect and drain the incoming ice-making
water line at the rear of the ice machine.
5. Blow compressed air in both the incoming water
and the drain openings in the rear of the ice
machine until no more water comes out of the inlet
water lines or the drain.
6. Make sure water is not trapped in any of the water
lines, drain lines, distribution tubes, etc.

WATER-COOLED ICE MACHINES

1. Perform steps 1-6 under "Self-Contained Air-
