READ & SAVE THESE INSTRUCTIONS

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 at the address or
telephone number listed in the warranty.

2. Before servicing or cleaning unit, switch power off at service
panel and lock 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
personnel 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 for Heating, Refrigeration 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.

8. Never place a switch where it can be reached from a tub or shower.

9. When applicable local regulations comprise more restrictive
installation and/or certification requirements, the aforementioned
requirements prevail on those of this document and the installer
agrees to conform to these at his own expenses.

10. When performing installation, servicing or cleaning this unit, it is

recommended to wear safety glasses and gloves.

CAUTION

For general ventilating use only. Do not use to exhaust hazardous
or explosive materials and vapors.

INSTALLATION INSTRUCTIONS

•

Suitable for use with solid state speed controls

•

Uses standard 3¼" x 10" ducting

•

Designed for ceiling installation

•

Do not mount over bathtub or shower stall enclosure

•

Not for use in kitchens

•

The ventilator consists of the housing, mounting brackets, junction box,
power unit/blower assembly, damper section and grille assembly

FAN MUST NOT BE INSTALLED IN A CEILING THERMALLY
INSULATED TO A VALUE GREATER THAN R-40.

FOR BEST RESULTS

•

When installing the ventilator in a new construction site, install the
housing during the rough-in construction of the building. The power
unit and grille should be installed after the finished ceiling is in place.

•

To install the ventilator in an existing building, an accessible area
(attic or crawl space) is required from above the planned location.

MOUNTING THE HOUSING

NOTE: These ventilators are designed for installation between
16" O.C. ceiling joists with no framing necessary. If the
building structure has 24" O.C. joists construction, framing
will be required.

1. Position housing between ceiling joists and adjust height to
finished ceiling. Loosen two hex nuts for each mounting bracket
from inside the housing and make the adjustment. Tighten the
four hex nuts.

NOTE: There are four additional mounting slots in the
housing for mounting or relocating the mounting brackets.

2. Refer to Figure 4. Screw housing to joists using holes
in mounting brackets and four screws (included).

3. Install standard 3¼" x 10" ductwork from damper section
to outside wall or through roof and mount appropriate wall or
roof cap (not included). Refer to the instructions provided with
the caps.

IMPORTANT: Ensure there are no obstructions at the
discharge of the ventilator. Ensure insulation does not get
into the ductwork or into the blower.

WIRING

NOTE: All wiring connections must comply with local codes,
ordinances and the National Electrical Code and the ventilator
must be properly grounded. Disconnect power at circuit
breaker before making wire connections.

1. Refer to Figure 5. Loosen screws and remove junction box.

2. Run 120 VAC supply wiring with ground through switch box to
knockout in ventilator housing and secure with box connector.

3. Refer to Figure 6. Connect supply wires to ventilator wires:
BLACK to BLACK, WHITE to WHITE. Connect ground wire to
GREEN ground lead.

4. Reinstall junction box and tighten screws.

5. Connect supply wire to switch.

NOTE: Switch must be purchased separately. Refer to
NuTone's catalog.

POWER UNIT INSTALLATION

1. Refer to Figure 7. The power unit mounts with two hanger rods
to the mounting brackets. Start threading wing nuts (included)
onto hanger rods. Insert the hanger rods through the holes in
the mounting bracket hooking them from the inside to the
outside.

2. Position the power unit so that its discharge opening is in line
with the installed ductwork. Hold the power unit in position
between the mounting brackets and swing the hanger rods into
the slots on the power unit and securely tighten the wing nuts.

3. Plug the three wire connectors from the junction box into the
wire receptacle connector from the power unit making sure the
plug is properly aligned.

WARNING: Risk of fire or electrical shock; disconnect the power

before cleaning or performing any maintenance on the ventilator.

•

If the grille becomes soiled, use only a mild soap and water
solution for cleaning. Do not use solvents or abrasive cleaners.

INSTALLATION
IN EXISTING CONSTRUCTION

Installing a ventilator in an existing construction site requires at
least a small accessible area (attic or crawl space) above the
planned installation location.

Review “INSTALLATION IN A NEW CONSTRUCTION SITE” and
follow all instructions which apply to your installation.

Locate the ventilator next to a ceiling joist.
Plan the ductwork and wiring before proceeding with the installation.
CAUTION: Check the area above the planned installation to

ensure that:

1. Ductwork can be installed or that the area is sufficient for proper

mounting.

2. Wiring can be run to the planned location.

3. No wiring or other obstruction will interfere with the installation.

INSTALLATION FROM ACCESSIBLE
AREA ABOVE (USING HEADERS)

1. From below the installation site, drill a small hole in ceiling at the
planned location.

2. Locate hole in attic or crawl space.

3. In attic or crawl space, mark ceiling for cutout by using the housing
as a template. Cutout dimensions: 10

3

⁄16" x 141⁄2". The short side

(10

3

⁄16") of the cutout must be right next to the ceiling joist.

4. Refer to Figure 9. Mark cutout along marked line.

NOTE: If ceiling is plaster, cutout should be made from
below to avoid chipping plaster.

5. Install headers between joists using nails or screws leaving
10

3

⁄16" between them.

6. Install brackets upside down on housing's long dimension using
hex nuts.

7. Mount damper section to housing, install housing and connect
wiring and ductwork. Install power unit/blower assembly and
grille.
