IMPORT
ANT SAFEGUARDS
• WARNING: Disconnect the power before beginning this
installation
• WARNING: To reduce the risk of fire or electric shock or
injury to persons observe the following:
Do not use this fan with any solid-state speed
control device.
Use this unit only in the manner intended by the
manufacturer.
Before servicing or cleaning the unit, switch power
off at the service panel. 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.
Installation work and electrical wiring must be
done by qualified person(s) in accordance with all
applicable codes and standards, including fire-rated
construction.
When cutting or drilling into wall or ceiling, do not
damage electrical wiring or other hidden utilities.
Ducted fans must always be vented to the outside.
Do not install this fan in a ceiling thermally
insulated to a value greater than R-40
• WARNING: Do not use in kitchens.
• WARNING: 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 guidelines and safety standards
such as those published by National Fire
Protection Association (NFPA), and the American
Society for Heating, Refrigeration and Air
Conditioning Engineers (ASHRAE), and local code
authorities.
• CAUTION: For general ventilating use only. Do not use to
exhaust explosive materials and vapors.
• Acceptable for use over tub or shower when installed in a
GFCI protected branch circuit.
• Never place a switch where it can be reached from the tub
or shower.
Before beginning this
installation remove the fan’s
blower housing (which
includes the motor, blade,
bracket and venturi) assembly
by removing the screw which
secures the venturi housing
to the fan housing (fig. 1).
Place this assembly and the
grill in the carton until
needed so they do not get
damaged.
Mounting the
Housing: New
Construction
Using the Hanging Brackets
(refer to fig. 2)
1. Insert the hanging brackets
in the slots provided in the
housing.
2. Remove the electrical cover (which holds the fan’s receptacle)
and place it somewhere handy. Select the most convenient
electrical knockout and remove it, then locate the fan housing
between the joists so that the bottom of the fan housing is
even with the planned finished ceiling.
3. Use screws or nails (not provided) to secure the hanger bars
to the ceiling joists.
Mounting the Housing: Existing Construction
1. Determine the desired location for the fan.
2. Drill a small hole through the ceiling at the chosen location
and stick the end of a coat hanger through the hole into the
attic to help locate the spot in the attic.
3. Check the chosen area from above to be certain that the
wiring can be installed and that the installation will not
interfere with any existing wiring. Remove the electrical
compartment cover (which holds the fan’s receptacle) and
place it somewhere handy. Select the most convenient
electrical knockout and remove it.
4. From above, position the housing between ceiling joists, and
use the housing as a template to mark the required cut out in
the ceiling.
5. After cutting out the required area, install the housing using
the hanging brackets as described above.
Ducting
NOTE: All ducting must comply with local building codes.
1. Connect the correct ducting to the fan, secure in place using
duct tape or a screw clamp. Always duct these fans to the
outside through the wall or roof cap. To ensure maximum air
delivery keep the length of duct and number of elbows to a
minimum.
Electrical Wiring
CAUTION: Make sure the power is switched off before
beginning this installation.
NOTE: All wiring must comply with local and national codes.
You must ground this unit.
1. Run wiring from the wall switch (not provided) to the housing
electrical compartment, 1 neutral (white), 1 ground (green or
bare copper), and 1 hot (black lead connected to the switch).
Secure the electrical wires to the housing with an approved
electrical connector (make sure you leave enough wiring in
the box to make the connection to the fan’s receptacle).
2. From where you have access to inside the fan’s junction box,
connect the white wire from the house to the white wire of
the fan’s receptacle, then connect the black wire from the fan
switch to the black wire of the fan’s receptacle (use approved
electrical connectors). Connect the ground wire to the green
ground screw in the fan’s junction box. Replace the fan’s wire
compartment cover.
Completing the Installation
1. After you have installed the housing in the ceiling, run
ducting from the unit to the outside and have made the
necessary electrical connections you can reinstall the venturi
and blower in the fan housing (fig. 3). Plug the fan’s blower
assembly into the fan’s
receptacle and secure the
blower housing with the
screw removed earlier.
Rotate the blower wheel
by hand to ensure it
revolves freely.
2. To install the grill, squeeze
the two ends of each
spring fastener together
and insert each into the
slots on the venturi. Push the grill up to the ceiling.
