MOUNTING THE HOUSING
1. Refer to Figure 3. Insert mounting brackets at each end of
housing.
2. Place long side of housing parallel to ceiling joist. Position housing
in desired location. Make sure housing flange is even with the
planned finished ceiling.
3. Use screws or nails (not provided) to secure mounting brackets to
ceiling joists.
4. Refer to Figure 1. Use 4" round duct to discharge the ventilator to
the outside.
IMPORTANT: Be sure nothing obstructs the discharge of
the ventilator. Make sure that insulation does not get into the
duct work or into the fan.
WIRING
Refer Figure 2.
1. Run 120v AC house power wiring (with ground) through switch box
to junction box in ventilator housing.
2. Remove ventilator junction box cover.
3. Connect house power wires to ventilator wires: black to black;
white to white. Connect ground wire to green ground screw.
4. Replace junction box cover.
5. Connect house power wire to standard toggle switch or use a
NuTone timer switch (sold separately.)
NOTE: BE SURE VENTILATOR AND SWITCH ARE PROPERLY
GROUNDED. ALL WIRING MUST COMPLY WITH LOCAL
ELECTRICAL CODES.
POWER/BLOWER UNIT INSTALLATION
1. Plug motor into socket in housing's junction box.
2. Position power unit over mounting screw in housing.
3. Slide unit forward using the guide on the blower housing to
engage opening in housing until mounting screw is seated in
narrow end of keyhole slot.
4. Refer to Figure 3. Securely tighten screw.
GRILLE INSTALLATION
1. Refer to Figure 3. Snap grille mounting springs' center loop into
notched bosses on the back of grille.
2. Place grille mounting springs into slots in housing sides.
3. Press grille firmly into place against the ceiling.
INSTALLATION IN EXISTING CONSTRUCTION
Installing the ventilator in an existing house requires an
accessible area (attic crawl space) above the planned installation
location.
Review "INSTALLATION IN A NEW CONSTRUCTION" and
follow all instructions which apply to your installation.
Location – locate ventilator parallel to a ceiling joist.
Wiring and Ducting – plan ducting and wiring before proceeding
with installation.
Refer to Figure 2 for wiring and Figure 1 for ducting.
CAUTION: Check area above planned installation to
be sure that:
1. Ducting can be installed.
2. Wiring can be run to the planned location.
3. No wiring or other obstructions might interfere with
installation.
