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. Use only ON/OFF switch, mechanical timer or relay-switched
control.
8. Acceptable for use over a tub or shower when connected to
a GFCI (Ground Fault Circuit Interrupter) - protected branch
circuit.
9. This unit must be grounded.
CAUTION
1. For general ventilating use only. Do not use to exhaust
hazardous or explosive materials and vapors.
2. This product is designed for installation in flat ceilings. Sensor
will not function reliably if product is not installed in flat ceiling.
DO NOT MOUNT THIS PRODUCT IN A WALL.
3. To avoid motor bearing damage and noisy and/or unbalanced

Typical Installation
• Installation is the same for:
Joists I-Joists Trusses
• Fits in 2" x 8" ceiling construction.
• Infinitely adjust the fan position
between joists from 14" to 24"
on center.
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.
6-inch round rigid metal duct is recommended for best performance.

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.
Operation
It is normal for this ventilation fan to take approximately 5 seconds to
start running after it is turned on.
Modes
(For reference, wiring diagrams are on pages 5 and 10.)
Continuous ventilation:
1. Turn master wall switch on.
2. Fan operates at user-adjustable airflow rate.
Motion sensing:
1. If master wall switch is not already on, turn it on.
2. Turn sensor/control wall switch on. Some installations may not have a
separate sensor/control wall switch; where it is combined with master
wall switch.
3. Fan operates at certified airflow rate and sensor detects motion.
4. When no more motion is detected, fan enters time delay mode. (See
below.)
Manual-on (optional manual-on wall switch must be installed):
1. Turn master and manual-on wall switches on (sensor/control wall
switch can be on or off).
2. Fan operates at certified airflow rate.
3. When manual-on wall switch is turned off, fan enters timed-off mode.
(See below.)
Time Delay:
Fan continues to run at cerified airflow rate until user-adjustable TIME
delay has passed, then fan reverts to user-adjustable airflow rate.
Cleaning and Maintenance
CAUTION
IN ORDER TO PREVENT MOTOR/
CONTROL DAMAGE:
DO NOT remove motor plug to stop spinning
motor.
Power must be disconnected (see
WARNING at top left of this page) before
motor plug is removed or inserted into
control assembly.
To Clean
For quiet and efficient operation, long life and
attractive appearance, remove Grille and
vacuum interior of unit with a dusting brush
attachment.
Do not use cleaning sprays, solvents or water
on, or near, the sensor.
Motor is permanently lubricated and never
needs oiling. If motor is making excessive or
unusual noises, replace Control Assembly
and Motor.
To Set the User-Adjustable Airflow Rate*
Using a small, flat-blade screwdriver, carefully rotate the CFM
adjustment until the arrow points to the desired airflow rate.
To Set the User-Adjustable Time Delay*
Using a small, flat-blade screwdriver, carefully rotate TIME adjustment
until the arrow points to the desired minutes of time delay.
* The user-adjustable controls are located in one corner of the Fan
Housing, behind the Grille.

Troubleshooting
Before continuing, turn off power as previously noted
in WARNING and CAUTION sections at the top of the
previous page.
Symptom: Fan does not run.
• Check for an open fuse or circuit breaker in building’s
service panel.
• Check two (2) plug-in connections for Motor and its
Control are seated firmly in place.
• Check two (2) plug-in connections for Sensor and its
Control are seated firmly in place.
• Check that Blower Wheel spins freely.
Symptom: Motion mode does not operate fan at certi-
fied air flow rate.
• Check two (2) plug-in connections for Sensor and its
Control are seated firmly in place.
Symptom: Fan runs erratically.
• Check that Blower Wheel is firmly attached to Motor
shaft and both spin freely.

Symptom: Fan seems noisy.
• Check that back draft damper in fan’s Duct Connector
pivots freely. Screws used to attach duct to Duct Connector may prevent damper from opening.
• Check that back draft damper in wall or roof cap pivots
freely. Dampers are sometimes mistakenly painted shut
or obstructed by bird or insect debris.
Symptom: Fan does not properly ventilate room.
• For spot ventilation, turn both master switch and sensor/
control wall switch ON, so sensor/control operates fan at
certified airflow rate.
• For spot ventilation followed by continuous ventilation,
increase the “TIME” setting of user-adjustable time delay.
• For continuous ventilation, increase “CFM” setting of
user-adjustable airflow rate.

Warranty
Broan Ventilation Fan/Lights Limited Warranty
WARRANTY PERIOD: Broan warrants to the original consumer purchaser
of its Broan Ventilation Fan/Light (the “Fan”) that your Fan (excluding lamps/
bulbs) will be materially free from defects in materials or workmanship for a
period of three (3) years from the date of original purchase. The warranty on
the lamps/bulbs provided with the Fan is one (1) year and does not cover
lamp/bulb breakage. This warranty does not cover accessories, such as
speed controls, that may be purchased separately and installed with the Fan.
The limited warranty period for replacement parts, and for Fans repaired or
replaced under this limited warranty, shall continue for the remainder of the
original warranty period.
NO OTHER WARRANTIES: THE FOREGOING WARRANTIES ARE
EXCLUSIVE AND IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR
IMPLIED. BROAN DISCLAIMS AND EXCLUDES ALL OTHER EXPRESS
WARRANTIES, AND DISCLAIMS AND EXCLUDES ALL WARRANTIES
IMPLIED BY LAW, INCLUDING WITHOUT LIMITATION THOSE OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. TO
THE EXTENT THAT APPLICABLE LAW PROHIBITS THE EXCLUSION
OF IMPLIED WARRANTIES, THE DURATION OF ANY APPLICABLE
IMPLIED WARRANTY IS LIMITED TO THE PERIOD SPECIFIED FOR THE
EXPRESS WARRANTY. Some states do not allow limitations on how long an
implied warranty lasts, so the above limitation may not apply to you. Any oral
or written description of the Fan is for the sole purpose of identifying it and
shall not be construed as an express warranty.
REMEDY: During the applicable limited warranty period, Broan will, at its
option, provide replacement parts for, or repair or replace, without charge,
any Fan or part thereof, to the extent Broan finds it to be covered by and in
breach of this limited warranty. Broan will ship the repaired or replaced Fan
or replacement parts to you at no charge. You are responsible for all costs
for removal, reinstallation and shipping, insurance or other freight charges
incurred in the shipment of the Fan or part to Broan. This warranty does not
cover (a) normal maintenance and service, (b) normal wear and tear, (c) any
Fans or parts which have been subject to misuse, abuse, abnormal usage,
negligence, accident, improper or insufficient maintenance, storage or repair
(other than repair by Broan), (d) damage caused by faulty installation, or
installation or use contrary to recommendations or instructions, (e) any Fan
that has been moved from its original point of installation, (f) damage caused
by environmental or natural elements, (g) damage in transit, (h) natural wear
of finish, (i) Fans in commercial or nonresidential use, or (j) damage caused
by fire, flood or other act of God. This warranty covers only Fans sold in the
United States or through U.S. distributors authorized by Broan.
EXCLUSION OF DAMAGES: BROAN’S OBLIGATION TO PROVIDE
REPLACEMENT PARTS, OR REPAIR OR REPLACE, AT BROAN’S
OPTION, SHALL BE YOUR SOLE AND EXCLUSIVE REMEDY UNDER
THIS LIMITED WARRANTY AND BROAN’S SOLE AND EXCLUSIVE
OBLIGATION. BROAN SHALL NOT BE LIABLE FOR INCIDENTAL,
INDIRECT, CONSEQUENTIAL OR SPECIAL DAMAGES ARISING OUT
OF OR IN CONNECTION WITH THE FAN, ITS USE OR PERFORMANCE.
Incidental damages include but are not limited to such damages as loss of
time and loss of use. Consequential damages include but are not limited to
the cost of repairing or replacing other property which was damaged if the
Fan does not work properly.
Some states do not allow the exclusion or limitation of incidental or
consequential damages, so the above limitation or exclusion may not apply
to you. This warranty gives you specific legal rights, and you may also have
other rights, which vary from state to state.
This warranty supersedes all prior warranties and is not transferable from the
original consumer purchaser.
BROAN SHALL NOT BE LIABLE TO YOU, OR TO ANYONE CLAIMING
UNDER YOU, FOR ANY OTHER OBLIGATIONS OR LIABILITIES,
INCLUDING, BUT NOT LIMITED TO, OBLIGATIONS OR LIABILITIES
ARISING OUT OF BREACH OF CONTRACT OR WARRANTY,
NEGLIGENCE OR OTHER TORT OR ANY THEORY OF STRICT LIABILITY,
WITH RESPECT TO THE FAN OR BROAN’S ACTS OR OMISSIONS OR
OTHERWISE.
This warranty covers only replacement or repair of defective Fans or parts
thereof at Broan’s main facility and does not include the cost of field service
travel and living expenses.
Any assistance Broan provides to or procures for you outside the terms,
limitations or exclusions of this limited warranty will not constitute a waiver
of such terms, limitations or exclusions, nor will such assistance extend or
revive the warranty.
Broan will not reimburse you for any expenses incurred by you in repairing
or replacing any defective Fan, except for those incurred with Broan’s prior
written permission.
HOW TO OBTAIN WARRANTY SERVICE: To qualify for warranty service,
