NuTone ILF360 User Manual

SHOCK, OR INJURY TO PERSONS, OBSERVE THE
FOLLOWING:
A. Use this unit only in the manner intended by the manufacturer. If

you have questions, contact the manufacturer.

B. Before servicing or cleaning unit, switch power off at service

panel and lock 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.

• Suitable for use with solid state speed controls.

For general ventilating use only. Do not use to exhaust

hazardous or explosive materials and vapors.

SHOCK, OR INJURY TO PERSONS, OBSERVE THE
FOLLOWING:
A. Installation work and electrical wiring must be done by qualified

person(s) in accordance with all applicable codes and standards,
including fire-rated construction.

B. 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.

C. When cutting or drilling into wall or ceiling, do not damage electrical

wiring and other hidden utilities.

D. Ducted fans must always be vented to the outdoors.
E. NEVER place a switch where it can be reached from a tub or shower.

When installing the Ventilator in a new construction site, install

fan and ducting during the rough-in construction of the building. Inlet
grille(s) should be installed after the finished ceiling is in place.

To install a ventilator in an existing building requires access to

the attic area above the space to be ventilated.

1. Select a mounting site; Identify a mounting location that offers

accessibility with minimal duct run.  Mount ventilator as far from
the inlet grille as practical to minimize noise.

If used for dryer boosting the ventilator must be mounted at

least 12 feet from the dryer outlet.  For gas fired dryers the
ventilator capacity (CFM) must not exceed the dryer’s fan
capacity.

2. Attach fan mounting bracket to the support joist using the wood

screws provided (Refer to Figure 1).  For best performance
vertical mounting is recommended, however any orientation is
acceptable.

3. Attach fan to the mounting bracket using the self threading

screws provided (Refer to Figure 1). To ease attachment

pilot holes may be used for the mounting screws.

1. Run 120v AC house power wiring through switch box to junction

box in ventilator housing.

2. Remove ventilator junction box cover.
3. Refer to Figure 2. Connect the house power wire (black) to the
terminal marked LI.  Connect the house neutral wire (white) to the
terminal marked N. The fan housing is fully insulated and therefore
no grounding is required.
4. Replace outlet box cover.
5. Connect house power wire to the wall switch.

1. Refer to Figure 3. Attach duct to ventilator inlet and outlet using

clamps, fasteners and/or duct tape.  Observe the following
recommendations for best results;
A. Always minimize duct lengths and turns.
B. When flexible ducting is used be sure that the duct is fully 
stretched and free of kinks or sharp bends.
C. Use insulated ducting when passing through unconditioned spaces.
D. When insulated ducting is used clamp or tape the inner vinyl core to
the inlet and outlet of the fan and tape the vapor barrier surrounding the
duct insulation to the fan housing.
E. Always install a damper at the inlet grilles.
