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 Nation Electrical Code (NEC) and the
Occupation Safety and Healthy 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 configured
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.
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 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 qualified person(s) in accordance with all
applicable codes and standards, including
fire-rated construction.
4. Sufficient air is needed for proper combustion and
exhausting of gases through the flue (chimney) of
fuel burning equipment to prevent back drafting.
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 of
Heating, Refrigerating 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. 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. Do not use this unit with any other solid-state
control devices. Solid-state control devices may
cause harmonic distortion, which can cause a
motor humming noise. noise. (Avertissement: ne
convient pas à des régulateurs de vitesse à
semi-conducteurs).
9. NEVER
NEVERNEVER
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 R50. (This is required for
installation in Canada only).

1. INSTALLATIONS
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
the building has a strong effect on the air flow, 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 flow.
MOUNT HOUSING WITH FLANGE(CELING/ WALL):
