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
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.
