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 qualied person(s) in accordance with all applicable
codes and standards, including re-rated construction.

4. Su󰀩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 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 su󰀩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.

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 e󰀨ect 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.
