GENERAL SAFETY INFORMATION
READ AND SAVE THESE INSTRUCTIONS
GENERAL SAFETY INFORMATION
1. Make sure that the electric service supply voltage is AC
120V, 60Hz.
2. Follow all local electrical and safety codes, as well as
the National Electrical Code (NEC) and the Occupational
Safety and Health Act (OSH Act).
3. Always disconnect the power source before working on
or near the ventilating fan, motor or junction box.
4. Protect the power cord from sharp edges, oil, grease,
hot surfaces, chemicals or other objects.
5. Do not kink the power cord.
6. Do not install the unit where ducts are confugured as
shown in Fig.A.
7. Provide suction parts with proper ventilation.
8. This unit is UL Listed for use over a bathtub or shower
when installed in a GFCI protected branch circuit.
9. These ventilating fans are intended for residential usage
only.
10. This product is designed for ceiling installation only. Do
not mount this product in a wall.
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.
2. Before servicing or cleaning the unit, switch the power o
at the service panel and lock the service disconnecting
means to prevent the 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 qualied person(s) in accordance with all applicable
codes and standards, including re-rated construction.
4. Sucient air is needed for proper combustion and
exhausting of gases through the ue (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 local code authorities.
5. When cutting or drilling into the wall or ceiling, do not
damage electrical wiring and other hidden utilities.
6. Ducted ventilating fans must always be vented to the
outdoors.
7. 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
lnterrupter) – protected branch circuit.
8. Do not use this unit with any other solid-state control
device. Solid-state controls may cause harmonic
distortion, which can cause a motor humming noise.
9. NEVER place a switch where it can be reached from a
tub or shower.
10. Not to be installed in a ceiling thermally insulated to a
value greater than R40. (This is required for installation
in Canada only).

PREPARATION
Tools Required for Assembly (not included): Hammer,
Flathead Screwdriver, Wire Nuts, Nails, Duct Tape, Phillips
Head Screwdriver, Utility Knife
Helpful Tools (not included): Electric Drill, Drill Bits
WARNING: Turn o electricity at breaker box before
beginning installation.
Carefully remove unit from carton.
Check area above installation location to be sure that
wiring can run to the planned location and that duct work
can be run. Make sure the area is sucient for proper
ventilation.
Inspect duct work and wiring before proceeding with
installation.
Before installation, provide inspection and future
maintenance access at a location that will not interfere
with installation work.
You may need the help of a second person to install this
fan: one person on the attic side and one on the room
side.
Note: Installations may vary depending on how the previous
bath fan was installed. Supplies necessary for the installation
of your bath fan are not all included.
However, most are available at your local home improvement
or hardware store.

Proper insulation around the fan to minimize building heat
loss and gain. 4” circular duct is recommended for installation.
The ducting from this fan to the outside of building has a
strong eect on air ow, 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 air ow.

for compatibility
Humidity sensing models :
Locate unit above (GFCI-protected circuit required) or
within 5 feet of the shower head.
Locate unit away from heating or cooling sources which
can aect humidity levels.
Do not locate near window. Unit may respond to
the outdoor humidity level.
Unit must be installed in ceiling to properly sense
moisture.
Locate unit only on at ceilings up to 12 feet high for
proper sensing.

OPERATION
Single Speed Model:
Turn the POWER switch ON to operate at single speed mode.
Humidity Sensor Models:
1. Humidity Sensing Mode: Flip wall switch to “ON” position. The LED indicator light in the fan will be BLUE. The
fan will automatically start when the humidity level in the room is above the user-adjustable set-point.
If humidity level is below the user-adjustable set-point, until a 10-minute time delay has elapsed the fan will
stop automatically. Factory setting is around 60%RH and humidity tolerance is about ±10%. The humidity
switch may need to be adjusted regionally. Longtime operation will inuence the detecting precision as dust
accumulates.

1. Make sure power supply is on.
2. Test or replace switch.
3. Check wire in switch box.
1. Be sure the CFM rating on the fan matches the
size of your room.
2. Check damper to ensure it is opening and
closing properly. If the damper has become
damaged, please call Customer Service.
3. Be sure you do not have any sharp bends in
duct closer than 18 in. to the fan discharge.
4. Use recommended size ducting to reduce fan
noise.
5. Be sure the fan is securely attached to your
ceiling joists.
1. Be sure a door or window is slightly ajar or
opened to allow airow. The fan is not able to
draw air out of the room without enough airow
to draw in from.
2. Be sure the CFM rating on the fan matches the
requirements for your room size.
