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 move-
ment in the event of variable speed control difficulties.
