MAINTENANCE

Motor is permanently lubricated. Do not oil or disassemble motor. See "Service Parts" section for a list and illustrations of service parts.

PLAN THE INSTALLATION

The unit can be installed anywhere between ceiling joists using mounting brackets provided.

*Install in a fl at ceiling only.

Two of the most common ways to connect ductwork to the unit.

Ducting 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. The unit will operate most quietly and efficiently when located where the shortest possible duct run and minimum number of elbows will be needed.

Plan to supply the unit with proper line voltage and appropriate power cable.

Do not install in a cooking area.

INSTALLATION

CARDBOARD PROTECTOR

1. Install mounting brackets.

Slide the adjustable mounting brackets into the bracket channels on the housing.
Bend the tabs on the cardboard protector and insert protector into opening in housing.
NOT: The cardboard protector shields the inside of the housing from drywall spray and construction dust. Do not remove it until after construction is completed.

2. Mark mounting location.

Position unit between joists and extend mounting brackets. IMPORTANT: Position brackets so there will be an 1/8" gap between bottom of housing and ceiling material. Mark the top of keyhole slot on all four mounting brackets.

3. Pound in nails.

Remove unit temporarily, and pound nails partially into joists at all four marked locations.

4. Hang and secure housing.

Hang unit from nails. Check to make sure that there will be a 1/8" gap between bottom of housing and ceiling material. Pound nails tight. For wide joist centers: A #8 x 3/8 self-tapping screw can be used to join extended brackets together and create a rigid mount. To ensure a noise-free mount, crimp the bracket channels tightly around mounting brackets.
