WARNING

To reduce the risk of fire, electric shock, or injury to persons, observe the following:

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.
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.
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.
Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent back drafting. 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.
When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
Ducted fans must always be vented to the outdoors.
This unit must be grounded.

CAUTION

For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
For installation in flat ceilings only.
To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust, etc. off power unit.
Please read specification label on product for further information and requirements.

CLEANING & MAINTENANCE

For quiet and efficient operation, long life, and attractive appearance – remove grille and vacuum interior of unit with the dusting brush attachment.

The motor is permanently lubricated and never needs oiling. If the motor bearings are making excessive or unusual noises, replace the blower assembly (includes motor and impeller).

OPERATION

Use an on/off switch or speed control to operate this ventilator. See “Wiring Diagram” for details.

ALL INSTALLATIONS

Start here.

IMPORTANT – 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, straightest 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.

OPTION – To mount housing anywhere between ceiling framing: Use optional Hanger Bar Kit (sold separately from local distributors or website). Follow mounting instructions included with kit.

Remove blower and all packing material from fan housing.
Remove wiring panel from fan housing (if already installed).
A pair of flanges may be attached to housing if desired or required.
Snap both flange pieces under rolled-over edge of housing (all four sides).
Attach grille brackets* to housing.

Grille brackets are located in Styrofoam packing material in box.
