WATER FILTER REPLACEMENT
The water filter should be replaced every six months or
after a prolonged shutdown. To replace the water filter,
incoming water does not need to be turned off. The ice
machine is equipped with an auto bypass feature which
bypasses the filter when it is removed.
IMPORTANT NOTE: Poor water quality may require more
frequent water filter replacement.
To remove, turn the water filter one-quater turn counter-
clockwise and it will pop out. Refer to the illustration
below. Reverse the process to install the new water filter.
Replacement water filters can be ordered by calling
800-222-7820 or online at subzerowolfstore.com.

PROLONGED SHUTDOWN AND WINTERIZATION
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
Follow these steps:
1) Perform a cleaning and sanitizing procedure to prevent
mildew growth.
2) Disconnect the electrical power at the circuit breaker or
service panel.
3) Turn off the water supply.
4) Remove the water from the water reservoir.
5) Disconnect the incoming water supply line at the rear
of the ice machine and allow it to drain.
6) Disconnect the vinyl hose from the water pump and
allow it to drain.
7) Make sure water is not trapped in any of the water
supply or drain lines. Compressed air can be used to
blow out the lines.
8) Use a spray bottle with a solution of 1 tablespoon
sanitizer to 1 gallon
(15 ml)
interior surfaces. Do not rinse, allow it to air dry.
9) Block the door partially open to provide air exchange
and prevent mildew growth.
If water is allowed to remain in the ice machine in
freezing temperatures, damage to some components
could result. Damage of this nature is not covered by
the warranty.
