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 pre-
vent 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 electri-
cal wiring and other hidden utilities.
6. Ducted fans must always be vented to the outdoors.
7. If this unit is to be installed over a tub or shower, it must be marked
as appropriate for the application and be connected to a GFCI
(Ground Fault Circuit Interrupter) - protected branch circuit.
8. Never place a switch where it can be reached from a tub or
shower.
9. To reduce the risk of electrical shock, do not use this fan with
any solid-state speed control.
10. Not for use in kitchens.
11. Do not install in a ceiling insulated to a value greater than R-
40.
12. This unit must be grounded.

CAUTION

1. For general ventilating use only. Do not use to exhaust hazard-
ous or explosive materials and vapors.
2. To avoid motor bearing damage and noisy and/or unbalanced
impellers, keep drywall spray, construction dust, etc. off power
unit.
3. Please read specification label on product for further information
and requirements.
FOR BEST RESULTS
When installing the Exhaust Fan/Light in a new construction site,
install housing during the rough-in construction of the building. The
blower unit, reflector and grille should be installed after the finished
ceiling is in place.

Planning DUCTWORK AND WIRING

DUCTWORK

1. Use 4" round duct.
2. Plan duct run from discharge opening of fan to the outside. For
best fan performance, make duct run as short as possible and
use minimum number of elbows.
3. Use optional Broan ducting accessories as needed.
Plan to run 120 VAC house wiring (with ground) from power source,
through wall switch, to junction box in housing. For separate control
of fan and light use an optional Broan switch.
IMPORTANT: Use wire suitable for 90
