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.

CAUTION
1. For general ventilating use only. Do not use to exhaust hazardous
or explosive materials and vapors.
2. For installation in flat ceilings only. Do not mount this product in a
wall.
3. To avoid motor bearing damage and noisy and/or unbalanced
impellers, keep drywall spray, construction dust, etc. off power unit.
4. DO NOT TOUCH THE HUMIDITY-SENSING CIRCUIT BOARD.
Electrostatic discharge may damage the circuit board.
5. Please read specification label on product for further information
and requirements.
CLEANING & MAINTENANCE
For quiet and efficient operation, long life, and attractive appearance

OPERATION
The humidity sensor and fan can be operated separately. Use an on/off
switch or a 2-function wall control.
Do not use a speed control to operate the humidity sensor or the fan.
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 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.
