CONSTRUCTION FOR WINTER WEATHER PROTECTION
If your area is subject to snow, consideration must be taken to protect from the possibility of snow and ice
building up on the roof and sliding down onto the fan and cone. One option is to build a small section of roof over
the fan and cone. See Figure 20.
WARNING
Protect Fan and Cone from Snow
and Ice Buildup
WARNING
Fan and/or cone damage caused by this type of external source WILL NOT be
covered by AMERICAN COOLAIR warranties.

During winter months, you may not need to operate all of your fans. It is advisable to seal up those fans which will
not be used during the colder months to minimize heat loss as well as condensation. To do this, turn the fan control
off, and insulate the fan intake.
