FAN MUST NOT BE INSTALLED IN A CEILING INSULATED TO A VALUE GREATER THAN R-40.

SUITABLE FOR USE OVER TUB OR SHOWER ENCLOSURE WHEN INSTALLED IN A GFCI PROTECTED BRANCH CIRCUIT.

FOR BEST RESULTS

When installing the Exhaust Fan in a new construction site, install the housing during the rough-in construction. The blower unit and grille should be installed after the finished ceiling is in place. To install the Exhaust Fan in an existing finished building, an accessible area is required above the planned location (attic or crawl space).

IMPORTANT SAFETY INSTRUCTIONS

WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:

A. Use this unit only in the manner intended by the

manufacturer. If you have questions, contact the manufacturer.

B. Before servicing or cleaning unit, switch power off at service

panel and lock service panel 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.

CAUTION: For general ventilating use only. Do not use to exhaust

hazardous or explosive materials and vapors. WARNING: To reduce the risk of fire or electric shock, do not use this fan with any solid-state speed control.

PLANNING DUCTWORK AND WIRING

Ductwork

1. Use 4” round duct.

2. Plan to run duct from discharge opening of fan to the outside. For best fan performance, make the duct run as short as possible and use a minimum number of elbows.

3. Use optional ducting accessories as required.

Wiring

Plan to run 120vAC house wiring (with ground) from the power source through a standard wall switch.

Preparation

1. Refer to Figure 1. Remove blower/power unit assembly from the housing.

(a) Unplug the power unit. (b) Remove the screw (located next to plug-in receptacle)

which holds blower/power unit mounting plate in place. Do not misplace this screw.

receptacle until blower wheel clears the scroll.

(d) Remove plate by pulling its tabs out of slots in the

housing. Set blower/power unit aside until needed.

2. Remove one of the wiring knockouts from housing.

MOUNTING THE HOUSING

Mounting Using Mounting Tabs Refer to Figure 2.

1. Locate fan housing next to ceiling joist.

2. Using wood screws (not provided) loosely attach the housing to ceiling joist through the keyhole slots in mounting tabs.

3. Adjust housing so that it will be flush with the finished ceiling. For the grille to fit properly, the housing’s rim must not extend beyond finished ceiling surface.

4. When housing is properly adjusted, tighten screws in slots.
