device, such as a tag, to the service
panel.
•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.
•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.
•When cutting or drilling into wall or ceiling,
do not damage electrical wiring and other
hidden utilities.
•Ducted fans must always be vented to
the outdoors.
•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.
•This unit must be grounded.
•Some metal edges and/or corners may
be sharp. Use of gloves during installation
and removal is recommended.
CAUTION
•For general ventilating use only. Do not
use to exhaust hazardous or explosive
materials and vapors.
•For installation in flat ceilings only. DO
NOT MOUNT THIS PRODUCT IN A
WALL.
•To avoid motor bearing damage and
noisy and/or unbalanced impellers, keep
drywall spray, construction dust, etc. off
power unit.
•DO NOT TOUCH THE HUMIDITY-
SENSING CIRCUIT BOARD.
Electrostatic discharge may damage the
circuit board.

OPERATION

CLEANING & MAINTENANCE
For quiet and efficient operation, long life, and
attractive appearance - lower or remove grille
and vacuum interior of unit with the dusting brush
attachment.
The motor is permanently lubricated and never needs
oiling. If the motor bearings are making excessive
or unusual noises, replace the blower assembly
(includes motor and impeller).
OPERATION
The humidity control, fan, and light can be operated
separately. Use a 2- or 3-function wall control. Do
not use a dimmer switch to operate the humidity
control.
SENSOR OPERATION
This humidity-sensing fan uses a sophisticated
humidity sensor that responds to: (a) rapid to
moderate increases in humidity or (b) humidity above
a set-point. The humidity sensor may occasionally
turn the fan ON when environmental conditions
change.
MANUAL ON WITH TIMED OFF
This humidity sensing fan has an additional operation
feature. For odor or vapor control, the fan can be
energized by cycling the power switch. Once the fan
has been energized in this manner, it will remain on
for the set timer period.
To manually energize the fan:
1. If fan power switch is already ON, proceed to
Step 2; otherwise, turn power switch ON for more
than 1 second.
2. Turn fan power switch OFF for less than 1
second.
3. Turn fan power switch back ON and fan will turn
ON.

%HUMIDITY MINUTES
% HUMIDITY ADJUSTMENT
%HUMIDITY has been factory set at 80% for most
shower applications. If fan is not responding to changing
humidity conditions, adjust toward 50%. If fan is
responding too often to changing humidity conditions,
adjust toward 80%. If fan is still responding too often at
80%, contact Broan Technical Support.
To adjust the %HUMIDITY:
1. Turn power off at electrical service panel.
2. Use a small screwdriver to carefully rotate
%HUMIDITY control to desired level.
3. Turn power on.
4. Repeat above steps if necessary.
MINUTES ADJUSTMENT (TIMER)
This humidity-sensing fan has a timer that controls how
long the fan remains on after (a) rise in humidity and
(b) humidity level are both below the user-adjustable
%HUMIDITY setting, or after being energized by cycling
power switch.
To adjust the timer:
1. Disconnect power at electrical service panel.
2. Use a small screwdriver to carefully rotate MINUTES
control to increase or decrease time.
3. Turn power on.
4. Repeat above steps if necessary.
Factory settings shown.
SENSOR CLEANING
The humidity sensor is mounted in the control housing. The
sensor will operate most reliably when cleaned occasionally
as follows:
1. Disconnect power at service entrance.
2. Remove the grille. Use a dry dustcloth, clean toothbrush,
or lightly vacuum to clean sensor and grille. DO NOT
USE ABRASIVE CLOTH, STEEL WOOL PADS, OR
SCOURING POWDERS.
3. DO NOT USE cleaning sprays, solvents, or water on or
near the sensor!

IMPORTANT - 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, 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.
