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.
Typical Installation
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
impellers, keep drywall spray, construction dust, etc. off power
unit.
4. Please read specification label on product for further
information and requirements.

The ducting from this fan to the outside of the building has a strong effect on the air flow, noise and en-
ergy 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 en-
ergy 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.)
Humidity sensing:
1. Turn sensor/control wall switch on (make sure manual-
on wall switch is off if it is installed).
2. Sensor monitors humidity level for (a) moderate to rapid
rise or (b) above set-point.
3. Fan operates at certified airflow rate to reduce humidity.
4. When humidity decreases, fan enters time delay mode.
(See below.)
Manual-on (optional manual-on wall switch must be
installed):
1. Turn manual-on wall switch on (sensor/control wall
switch can be on or off).
2. Fan operates at certified airflow rate.
3. Fan turns off when manual-on wall switch is turned off.
Toggle (for manual operation when optional manual-on
wall switch is not installed or manually activated timed-
off is desired):
1. Turn sensor/control wall switch on (make sure manual-
on wall switch is off if it is installed).
2. Wait at least one-second.
3. Turn switch off for less than one-second.
4. Turn switch back on.
5. Fan will operate at certified airflow rate and enter time
delay mode. (See next.)
Time Delay:
Fan continues to run until user-adjustable TIME delay has
passed, then fan turns off.
To Set User-Adjustable Humidity Sensitivity**
Using a small, flat-blade screwdriver, carefully rotate HU-
MIDITY adjustment until arrow points to desired humidity
level shown in percent relative humidity (%RH).
To Set 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.
** User-adjustable controls are located in corner of Fan
Housing behind Grille.

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.
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.
Troubleshooting
Before continuing, turn off power as previously noted
in WARNING section on previous page and CAUTION
section at the top of this page.
Symptom: Fan does not run.
• Check for an open fuse or circuit breaker in the build-
ing’s service panel.
• Check that the two (2) plug-in connections for the Motor
and the Control are seated firmly in place.
• Check two (2) plug-in connections for Sensor and its
Control are seated firmly in place.
• Check that the Blower Wheel spins freely.
Symptom: Humidity mode does not operate fan.
• Check two (2) plug-in connections for Sensor and its
Control are seated firmly in place.
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 Con-
nector 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.
CAUTION
IN ORDER TO PREVENT MOTOR/CONTROL DAMAGE:
DO NOT remove motor plug to stop spinning motor.
Power must be disconnected (see WARNING on previous
page) before motor plug is removed or inserted into control
assembly.
