SAFETY INFORMATION
Please read and understand this entire manual before attempting to assemble, operate or installthe product.
• Always disconnect the power supply prior to servicing
the fan, motor or junction box.
• Follow all local building, safety and electrical codes
as well as NEC (National Electrical Code) and OSHA
(Occupational Safety and Health Act).
• Electric Service supply must be 120 volts, 60 hertz.
• This product must properly connect to the grounding
conductor of the supply circuit.
• Do not bend or kink the power wires.
• Do not use this fan with any solid state control device,
such as a remote control, dimmer switch, or certain
timers. Mechanical timers are not solid state devices.
• Do not install in a ceiling with insulation greater than
R40.
• Duct work should be installed in a straight line with
minimal bends.
• Duct work size must be the same size as the discharge
and should not be reduced. Reducing the duct size
may increase fan noise.
WARNING: To reduce the risk of re, electric
shock, or injury to persons, observe the
following:
1. Use this unit in the manner intended by the manufac-
turer. If you have any questions, please call customer
service.
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 qualied person(s) in accordance with all applicable
codes and standards, including re-rated construction.
4. Sufcient 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 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 Interrupter)
protected branch circuit.
8. This ventilation fan is intended to be installed at least
3 ft. 3-1/4 in. (1 m) from the showerhead when installing
over a bathtub or shower. Installation within a shower
stall is not recommended for this unit, unless the
3 ft. 3-1/4 in. (1 m) distance can be met.
CAUTION
• For general ventilating use only. Do not
use to exhaust hazardous or explosive
materials and vapors.
• Not for use in cooking areas.
• To reduce the risk of injury to persons,
install the fan at least 7 feet (2.1m) above
the oor.

hardware contents. If any part is missing or damaged, do not attempt to assemble, install or operate the product. Contact
customer service for replacement parts at 1-877-319-3757, 7:30 a.m. - 4:30 p.m., CST, Monday - Friday.
Tools Required for Assembly (not included): Hammer, Flathead Screwdriver, Wire Connectors, Nails, Duct Tape, Phillips Head
Screwdriver, and Utility Knife or Drywall Saw.
Helpful Tools (not included): Electric Drill, Drill Bits

PREPARATION
Before removing your current ventilation unit, verify your switch box on the wall has the required supply wires
necessary for this installation. These supply wires are power/black and neutral/white (refer to right side of wiring
diagram below) at the switch. If you do not see both of these wires, consult a licensed electrician.
Check area above installation location to be sure that wiring can run to the planned location and that duct work can be run
and the area is sufcient 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: Installation 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.

WARNING: RISK OF ELECTRIC SHOCK. Ensure the
electricity to the wires you are working on is shut off.
Either remove the fuse or turn off the circuit breaker
before removing the existing bath fan or installing the
new one.
1. Place the fan housing (A) next to a ceiling joist or wall stud. The
fan housing (Å) should be level and perpendicular to the joist
or stud. Allow for thickness of ceiling board or drywall used in
your application. DO NOT ush mount to joist. Bottom of the
fan housing should be ush with ceiling board or drywall.

2. Before mounting the fan housing (A) to the joist or wall stud,
remove the plastic duct connector for easier access to the
mounting hole on the fan housing (A).
Remove the duct connector by inserting a at head screw
driver between the plastic and metal of the fan housing (A),
then GENTLY pry the duct connector off.

5. Remove the wiring cover. Pull the house wires through the
wiring cover hole. Using the attached quick connectors,
connect 120v house wiring to the fan as shown in the wiring
diagram on page 5. 12-18 AWG is the smallest conductor that

Carefully push the connected wires back into the wiring box
housing. Reattach the wiring box cover.
CAUTION: If the house electrical wires do not match the
colors from the fan wiring diagram on page 5, you must
determine what each house wire represents before
connecting. You may need to consult an electrical
contractor to determine safely.

TROUBLESHOOTING
PROBLEM POSSIBLE CAUSE SOLUTION
The fan seems louder than it
should. The CFM is too great. Be sure the CFM rating on the fan matches the square footage of your room.
The damper is damaged or not working properly. Check the damper to ensure it is opening and closing
properly. If the damper has become damaged, please
call Customer Service.
The bend in the duct is too close to the fan dis-
charge.
Be sure you do not have any sharp bends in the duct
within 18 in. of the fan discharge.
The fan discharge is reduced to t a smaller duct. Use the recommended size ducting to reduce fan
noise.
The fan body is not attached securely. Be sure the fan is securely attached to the ceiling
joists.
The fan is not clearing
humidity from the room. There is insufcient airow intake in the room. Be sure a door or window is slightly ajar or open to allow airow. The fan is not able to draw air out of the
room without enough airow.
There is insufcient CFM.
NOTE: Using a tissue is not the correct method for
determining if the fan is operating properly. If the fan
clears steam from the room within approximately 15
minutes of completing your shower, then the fan is
operating properly.
Be sure the CFM rating of the fan matches the
square footage of your room.
The fan keeps running even
though the humidity level is
lower than 60% RH.
NOTE: Our sensor tolerance
is +/-10% RH.
Outdoor humidity is back drafting into the fan. Continue to let fan run since it is good to keep venting
the house and the electric cost is minimal (estimated
at less than $10 per year).
If the light on the grille is red, the fan is in full speed
mode and not humidity sensing mode and will not
shut off automatically.
Turn the fan off when not in use.
