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 wall or 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

1. For general ventilating use only. Do not use to exhaust

hazardous or explosive materials and vapors.

2. When installed in a wall or sloped ceiling, the duct connector must point up.

3. To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust, etc. off power unit.

The ducting from this fan to the outside of the building has a strong effect on the 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.
