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

To Turn Fan ON

Turn the master switch ON.

• Fan will run at the certified airflow rate if the mode
select switch is ON.

• Fan will run at the user-adjustable airflow rate if the
mode select switch is OFF.

To Use Fan Time Delay Airflow Rate Change

1. Turn the master switch ON.

2. Turn the mode select switch ON - fan will run at the

certified airflow rate.

3. When the mode select switch is turned OFF, fan will

continue to run at the certified airflow rate until the
user-adjustable time delay has elapsed, and then will
automatically change to the user-adjustable airflow rate.

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 the
TIME adjustment until the arrow points to the desired time
delay, shown in minutes.

* The user-adjustable controls are located in one corner

of the Fan Housing, behind the Grille.

To Turn Fan OFF

Turn the master switch OFF.

To Operate Lights

The light and night light can be operated independently,
using separate on/off switches.

Cleaning and Maintenance

To Clean

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

The Motor is permanently lubricated and never needs
oiling. If the motor bearings are making excessive or
unusual noises, replace the Control Assembly and Motor.

To Change Bulbs

Refer to Retrofit Installation Step 14 (page 11).

1. Carefully insert a small flathead screwdriver between
the Grille and Lens, then twist to remove Lens.

2. Purchase two (2) 18W (max.)
type GU24 fluorescent
lamps with Maximum Overall
Length (MOL) of 3.9" (100
mm). Purchase a 4W (max.)
C7-type incandescent night
light bulb.

3. Insert bulbs into their
sockets. Replace Lens.

M.O.L.

3.9" (100 mm)

Troubleshooting

Symptom: The fan does not run.

• Check for an open fuse or circuit breaker in the

building’s service panel.

• Check that the two (2) plug-in connections for the Motor

and the Control are seated firmly in place.

• Check that the Blower Wheel spins freely.

Symptom: The fan runs erratically.

• Check that the Blower Wheel is firmly attached to the

Motor shaft and both spin freely.

Symptom: The fan seems noisy.

• Check that the back draft damper in the fan’s Duct

Connector pivots freely. Screws used to attach the duct
to the Duct Connector may be preventing the damper
from opening.

• Check that the back draft damper in the wall or roof cap

pivots freely. These dampers are sometimes mistakenly
painted shut or obstructed by bird and insect debris.

Symptom: The fan does not properly ventilate the room.

• For spot ventilation, turn both the master switch and the

mode select switch ON to enable the fan to run at the
certified airflow rate.

• For spot ventilation followed by continuous ventilation,

increase the “TIME” setting of the user-adjustable time
delay.

• For continuous ventilation, increase the “CFM” setting of

the 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,
you must (a) notify Broan at the address or telephone number stated below
within seven (7) days of discovering the covered defect, (b) give the model
number and part identification and (c) describe the nature of any defect in
the Fan or part. At the time of requesting warranty service, you must present
