Safety Information
READ AND SAVE THESE INSTRUCTIONS
PLEASE READ AND UNDERSTAND THIS ENTIRE
MANUAL BEFORE ATTEMPTING TO ASSEMBLE,
OPERATE, OR INSTALL THE 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
the National Electrical Code (NEC) and Occupational Safety and
Health Act (OSHA).
□Electric Service supply must be 120V, 60 Hz.
□This product must properly connect to the supply circuit’s
grounding conductor.
□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.
□If this unit is to be installed over a tub or shower, it must be
marked as appropriate for the application. When the fan is
going to be installed in the bathroom, the fan and the tub must
be more than 1.0 meters between each other. The fan must be
installed at the other side of the tub in ceiling. Acceptable for
use over a bathtub or shower when installed in a GFCI-protected
branch circuit.
WARNING: TO REDUCE THE RISK OF FIRE,
ELECTRIC SHOCK, OR INJURY TO PERSONS,
OBSERVE THE FOLLOWING: Use this unit in the
manner intended by the manufacturer. If you have any
questions. Please call customer service.
WARNING: Before servicing or cleaning the unit,
switch the power off at the service panel and lock the
service. Disconnect or disable any means by which the
power can be switched on accidentally. When the service
disconnection means cannot be locked, securely fasten
a prominent warning device, such as a tag, to the service
panel.
WARNING: 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.
WARNING: 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); the American Society
for Heating, Refrigeration and Air Conditioning Engineers
(ASHRAE); and local code authorities.
WARNING: When cutting the ceiling, do not damage
electrical wiring or other hidden utilities.
WARNING: Ducted fans must always be vented to the
outdoors.
CAUTION: For general ventilation use only. Do not use to
exhaust hazardous or explosive materials and vapors.
CAUTION: Not for use in cooking areas.
CAUTION: To reduce the risk of injury to persons, install
the fan at least 8 ft. (2.5 m.) above the oor.

Pre-Installation
TYPICAL INSTALLATION
The ducting from this fan to the outside of the building has a strong
effect on the 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.
Do not install ventilation fan in areas where the duct work will
require conguration as shown.
Ensure duct joints and exterior penetrations are sealed with
caulk or other similar material to create an airtight path,
minimize building heat loss and gain, and reduce the potential for
condensation.
Place/wrap insulation around the duct and/or fan to in order to
minimize possible condensation buildup within the duct, and
building heat loss and gain. Wall cap

PLANNING INSTALLATION
Before beginning the product installation, make sure all parts are present. Compare parts with the package contents list and hardware
contents. If any part is missing or damaged, do not attempt to install the product.
WARNING: Turn off the electricity at breaker box before
beginning installation.
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.
1. Carefully remove the unit from the carton.
2. Check the area above the installation location to be sure that
wiring can run to the planned location, that duct work can be
run, and that the area is sufcient for proper ventilation.
3. Inspect duct work and wiring before proceeding with
installation.
4. Before installation, provide inspection and future maintenance
access at a location that will not interfere with installation
work.

Care and Maintenance
WARNING: Disconnect the power supply before servicing.

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
discharge.
Be sure you do not have any sharp bends
in the duct closer than 18 in. to 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 steam from the
room.
There is insufcient airow intake in the room. Be sure a door or window is slightly ajar or
opened to allow airow. The fan is not able
to draw air out of the room without enough
airow to draw from.
There is insufcient CFM. Be sure the CFM rating on the fan matches the
requirements for your room size.
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.
The fan does not work. The wires are not connected properly. Be sure the wiring is connected in accordance
with the wiring instructions in the manual.
