READ ALL INSTRUCTIONS BEFORE USING THIS APPLIANCE.

When using an electric appliance, basic precautions should always be followed,
including the following:

WARNING

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR PERSONAL INJURY:

• Do not use on wet surfaces or outdoors.

• Do not allow to be used as a toy. Close attention is necessary when used by or
near children.

• Use only as described in this manual. Use only manufacturer's recommended
attachments.

• Do not put any object into openings. Do not use with any opening blocked; keep
free of dust, lint, hair, and anything that may reduce air flow.

• Keep hair, loose clothing, fingers and all parts of body away from openings and
moving parts.

• Do not pick up anything that is burning or smoking, such as cigarettes, matches,
or hot ashes.

• Do not use without dustbag or filter in place.

• Do not use to blow leaves or debris.

• Do not vacuum liquids or fine powders (such as drywall dust).

• Do not put any object on the unit.

• Ensure air flows freely to both side intake vents and exhausts unobstructed
from top outlet.

• Do not install the unit horizontally.

• Do not use the pail as a wash pail.

• Do not use the pail as a stool.

• Turn off all controls before unplugging.

• Use extra care when cleaning on stairs.

• Avoid picking up sharp objects.

• Do not use to pick up flammable or combustible liquids such as gasoline or use
in areas where they may be present.

• Do not use with damaged cord or plug. If appliance is not working as it should,
if it has been dropped, damaged, left outdoors, or dropped into water, return it
to a service center.

• Do not unplug the unit by pulling on cord. To unplug, grasp the plug, not the cord.

• Do not handle plug or appliance with wet hands.

• Connect to a properly grounded outlet only. See grounding instructions on
page 8.

• Any servicing other than that recommended in this manual should be
performed by an authorized service facility.

• We recommend that your unit be inspected by a specialized technician once a
year.

IMPORTANT SAFETY INSTRUC-

SAVE THESE INSTRUCTIONS

1. OPERATION

The power unit is located away from the everyday living areas of your home — usually
in the garage, basement, or utility room. Through a network of strong, lightweight
tubing, the power unit connects to inlets strategically placed throughout your
home. When you are ready to clean, attach the wand and cleaning tool onto the
end of the hose. Open the inlet cover and insert the end of the hose into the inlet.
For non-switched hoses: inserting the hose automatically turns on the power unit;
removing the hose shuts off the power unit. Some hoses have switches which can
be used to activate the power unit. As you vacuum, dirt and dust are transported
to the power unit where they remain in a disposable bag.

NOTE: The rocker switch on the front of the power unit can be used to turn the

power unit on.

Use the cleaning tools as you would for any other vacuum cleaner. Avoid picking
up pine needles, coffee sticks and other similar objects. These kinds of objects
may become lodged in the hose or tubing.

3. WHEN TO CHANGE BAG

With a 6 U.S. Gallons capacity, under normal conditions the bag requires
changing approximately twice a year. If the bag is filled, you will notice a complete
loss of vacuum in the system. Unless this loss of vacuum is caused by a blockage
in the system, changing the bag will solve the problem.

NOTE: Even if not filled to capacity, if the bag seems tightly stretched when

removing the debris pail, changing the bag will prevent it from tearing.

4. BAG REPLACEMENT

1. To remove the disposable bag, release both latches
on sides of the unit by pulling out and then
pushing up. Remove the pail from unit. Grasp the
edges of the bags’ collar and pull down. The bag
will slide off easily. Do not pull on the bag.

2. Unfold new bag.

3. Grasp collar where indicated on the bag and insert
over bag adapter. Be careful not to tear the bag.
Ensure that the collar is positioned between the
taper ring and the bag stopper on the bag adapter
(see illustration below). Put the pail back in its place.

NOTE : A set of 3 replacement bags (model 391) may be purchased from you local

NuTone Sales Outlet. To locate your nearest NuTone Sales Outlet, call toll
free 1-888-336-3948.

5. SECONDARY FILTER

A secondary safety filter, located at the top of the inlet chamber provides
protection against dirt being pulled into the motor if the disposable bag should
accidentally be torn. This filter should be checked and cleaned if necessary, when
replacement bag is installed. Simply brush filter clean. If the filter is excessively
soiled, wash in a mild detergent and let it dry completely

before reinstalling.

5.1 REMOVING FILTER

Remove debris pail and disposable bag.
Remove both locking sleeves from the
retaining hooks. Carefully pull filter down
to remove.

5.2 REINSTALLING FILTER

To reinstall the secondary filter, reverse
the steps described above.

NOTE: A replacement secondary filter (part no. 10941310) may be purchased from

you local NuTone Sales Outlet. To locate your nearest NuTone Sales
Outlet, call toll free 1-888-336-3948.

CAUTION

Operating the power unit without the secondary filter will void the
warranty.

6. POWER UNIT INSTALLATION

6.1 LOCATING THE POWER UNIT

• Locate the power unit away from the general living area in an accessible
location for cleaning and maintenance.

• Locate the power unit within 6 feet of a grounded electrical outlet. The power
unit requires a 120 VAC power source.

• Do not locate the power unit close to a source of extreme heat (i.e.: water
heater) or in an area with a high ambient temperature (i.e.: attic, furnace room).

• Do not locate the power unit where the temperature can drop below 0°C (32°F).

• If the power unit is located in a closet or a small utility room, make sure the area
is well-ventilated (i.e.: with door louvers).

NOTE: Refer to NuTone website for information on tubing installation

(www.nutone.com).

6.2 MOUNTING POWER UNIT

1. Carefully remove debris pail from power
unit. Make sure bag is properly installed in
power unit. Remove accessories and
installation kit. Securely reinstall pail.

2. Install the 3-way elbow on the back of the
power unit and press firmly (do not glue

).
Remove the plastic cap from the inlet
opening only if your installation requires the
connection into both inlets.

3. Install mounting bracket on a wall stud within
6 feet of a grounded electrical outlet, at the
distances specified on illustration beside.
Ensure that wall between mounting bracket
