BLOWER CARE
Even with good filters properly in place, blower wheels and motors will
become dust laden after long months of operation. The entire blower
assembly should be inspected annually. If the motor and wheel are
heavily coated with dust, they can be brushed and cleaned with a vac-
uum cleaner. Ifthe blower cannot be properly cleaned without removing
it from the furnace, then this service must be performed by a qualified
service agency.
Make sure you DO NOT move the clip on weight on the
indoor fan wheel when cleaning the wheel This weight is
used to balance the wheel. Moving the weight will cause
the fan wheel to vibrate.
