Winterizing
6.
In most climates, it is probable that the ventilation system will never need to operate at a total capacity
during the colder winter months. Consequently, it is advisable to “winterize” those fans which will not
be used in cold weather to avoid unnecessary heat loss and condensation.
To winterize, turn fan control “off”. Install the insulated closure panel over the fan intake. If you don’t
have an insulated closure panel, a piece of rigid insulation material can be used. Remember the
insulation panel must be removed before warmer weather returns.
NOTE:
At least one single speed fan should be left uncovered and with power available to provide air
movement in the event of variable speed control difficulties.
