CLEANING & MAINTENANCE
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR IN-
JURY TO PERSONS, OBSERVE THE FOLLOWING:
For quiet and efficient operation, long life, and attractive appear-
ance - lower or remove grille and vacuum interior of unit with the
dusting brush attachment.
1. Use this unit only in the manner intended by the manufacturer.
If you have questions, contact the manufacturer at the address
or telephone number listed in the warranty.
2. Before servicing or cleaning unit, switch power off at service
panel and lock the service disconnecting means to prevent

prominent warning device, such as a tag, to the service panel.
3. Installation work and electrical wiring must be done by a
qualified person(s) in accordance with all applicable codes

The motor is permanently lubricated and never needs oiling. If the
motor bearings are making excessive or unusual noises, replace
the motor with the exact service motor. The impeller should also
be replaced.

ment to prevent backdrafting. Follow the heating equipment
manufacturer’s guideline and safety standards such as those
published by the National Fire Protection Association (NFPA),
and the American Society for Heating, Refrigeration and Air

ties.
