WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR
INJURY TO PERSONS, OBSERVE THE FOLLOWING:
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
power from being switched on accidentally. When the service
disconnecting means cannot be locked, securely fasten
a 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
and standards, including fire-rated construction codes and
standards.
4. Sufficient air is needed for proper combustion and exhausting
of gases through the flue (chimney) of fuel burning equipment
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 Conditioning Engineers (ASHRAE), and the local code
authorities.
5. When cutting or drilling into a ceiling, do not damage electrical
wiring and other hidden utilities.
6. Ducted fans must always be vented to the outdoors.
7. Acceptable for use over a tub or shower (in the ceiling only)
when connected to a GFCI (Ground Fault Circuit Interrupter)
- protected branch circuit.
8. This unit must be grounded.
CAUTION
. For general ventilating use only. Do not use to exhaust
1
hazardous or explosive materials and vapors.
2. DO NOT install this unit onto an acoustic ceiling panel.
3. When installed in a sloped ceiling, the duct connector must
point up.
4. To avoid motor bearing damage and noisy and/or
unbalanced impellers, keep drywall spray, construction
dust, etc. off power unit.
5. Please read specification label on product for further
information and requirements.
NOT FOR USE IN A COOKING AREA
Do not install above or inside this area

Cooking
The ducting from this fan to the outside of the building has a strong effect on the
Equipment
air flow, noise and energy use of the fan. Use the shortest, straighest duct routing
possible for best performance, and avoid installing the fan with smaller ducts than
recommended. Insulation around the ducts can reduce energy loss and inhibit
mold growth. Fans installed with existing ducts may not achieve their rated airflow.
4-inch round rigid metal duct is recommended for best performance.

Operation

To Operate Fan
Use an ON/OFF switch or speed control to operate this
ventilator.
WARNING
Before servicing or cleaning unit,
switch power off at service panel and lock the service
disconnecting means to prevent power from being switched on
accidentally. When the service disconnecting means cannot be
locked, securely fasten a prominent warning device, such as a
tag, to the service panel.

Cleaning and Maintenance

To Clean
For quiet and efficient operation, long life and attractive
appearance, remove Grille and vacuum interior of unit with a
dusting brush attachment.
The Motor is permanently lubricated and never needs oiling. If
the motor bearings are making excessive or unusual noises,
replace the Motor.

Troubleshooting

Symptom: The fan does not run.
• Check for an open fuse or circuit breaker in the building's
service panel.
• Check that the plug-in connection for the Motor is seated
firmly in place.
• Check that the Blower Wheel spins freely.
Symptom: The fan runs erratically.
• Check that the Blower Wheel is firmly attached to the Motor
shaft and both spin freely.
Symptom: The fan seems noisy.
• Check that the back draft damper in the fan's Duct Connector
pivots freely. Screws used to attach the ducting to the Duct
Connector may be preventing the damper from opening.
• Check that the back draft damper in the wall or roof cap pivots
freely. These dampers are sometimes mistakenly painted shut
or obstructed by bird and insect debris.
