Cutting Tubing:

Measure the length of tube needed, allowing 5/8″ for inserting into fittings and 1 1/2″ for placing into flexible tubing. Cut the plastic tubing with a hacksaw, ensuring the cut is exactly square. Use a small knife or steel wool to remove any burrs from inside the tube. Use a file to slightly bevel the outside of the tube so it slides easily into the fitting. Buff the surface to be glued with steel wool or light-grained sandpaper.

Making a Joint:

1. Insert the tube into the fitting and align the parts as they will be installed. Mark the tube and fitting to help realign the joint.

2. Apply cement in an inch-wide band to the outside of the tube.

3. Insert the tube into the fitting with the alignment marks a quarter turn apart, then quickly push and turn the fitting to align the marks and spread the cement.

4. Allow 1 minute for the joint to dry.

Cementing Flexible Tubing:

Ensure the ends of the flexible tubing are even. Apply cement to both the inside of the flexible tubing and the outside of the plastic tubing or mounting plate tubing ring. Twist both pieces while joining them to evenly spread the glue. Allow 5 minutes for the cement to set.

Secure Wire to Tubing:

The low-voltage power wiring is run along with the tubing. Use electrical tape to secure the wire to the tubing approximately every 12″ to 18″.

1. Making the Wall Inlet Cutout:

The wall inlet should be located 18″ on-center from the floor. The wall inlet cutout must be exactly 3 7/8″ high by 2 7/8″ wide.

2. Attaching the Inlet Mounting Plate (V144):

Reach through the inlet hole, pull the flexible tubing through, and remove the low-voltage wiring from inside. Remove the nail flange from the inlet mounting plate. Apply cement to both the inside of the flexible tubing and the outside of the mounting plate’s tube ring. Insert the mounting plate’s tube ring into the flexible tubing, twisting as you join them to spread the cement. Align the mounting plate vertically. Strip the ends of the two low-voltage wires and connect them to the screw terminals on the back of the inlet cover. Assemble the inlet cover to the tube guard and mounting plate.

3. Completing the Inlet Assembly:

Once the mounting plate is attached, pull the low-voltage wire through the top wiring hole in the mounting plate.

4. Installing the Inlet (V111):

Place the inlet into the wall cutout, with the inlet cover remaining on the outside. Hold the inlet in place and gradually tighten each screw a little bit at a time.

Follow these guidelines for locating your NUTONE NC1500 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 unit requires a 120 VAC power source on a dedicated 15-amp branch circuit.

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

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

The intake line connects to the right side of the unit by default. To connect it to the left side, follow these steps:

1. Remove the debris pail from the power unit by releasing both latches on the sides of the unit, pulling them out and then pushing up.

2. For the NUTONE NC1500: Grasp the edges of the bag collar and pull down; the bag will slide off easily. Do not pull on the bag. Set the bag aside.

3. For the NUTONE NC1500: Using a Phillips no. 2 screwdriver, remove the screw tightening the bag adapter and intake elbow junction. Disassemble the bag adapter from the intake elbow and set it aside with its screw and nut.

4. All units: Disassemble the intake elbow from the back of the unit using a 3/8″ socket to remove both retaining nuts and screws.

5. All units: Flip the intake elbow 180°, then reassemble it to the unit, taking care to keep its gasket in its original position. Ensure the gasket is not folded to prevent lack of suction and noise.

6. For the NUTONE NC1500: Reassemble the bag adapter to the intake elbow. Align the triangle with the small inclined stud, then tighten the junction using the screw and nut previously removed.

7. For the NUTONE NC1500: Put the bag back in place by grasping the edges of its collar and inserting it over the bag adapter. Be careful not to tear the bag. Ensure the collar is positioned between the taper ring and the bag stopper on the bag adapter.

8. All units: Put the debris pail back in place.

1. Carefully remove the debris pail. Make sure the bag is properly installed (if needed). Remove the installation kit and securely reinstall the debris pail.

2. Maintain minimum clearance dimensions: 12″ minimum from side walls, 12″ minimum from the ceiling, and 18″ minimum above the floor.

3. Position and install the wall mounting bracket with the provided screws. Ensure to screw the wall mounting bracket directly to a wall stud for a solid installation.

4. Use the provided mounting screws to secure the mounting bracket on the wall through the upper and lower mounting holes.

5. Hang the power unit onto the wall mounting bracket. Ensure the back brackets of the power unit are engaged with the corresponding wall bracket top fingers and lower tab. Pull the power unit down to secure.

1. Run the house vacuum line up to the elbow behind the power unit. Insert the end of the line in the elbow opening and secure it by hand-tightening the screw and nut provided. DO NOT GLUE.

2. Assemble exhaust tubing to the exhaust outlet on the top or top side of the unit, according to the power unit model. DO NOT GLUE.

3. Make sure all tubing connections are airtight.

4. The exhaust should not be vented into a wall, ceiling, or concealed space in the house. It is recommended to vent the vacuum exhaust air to the outdoors. An exterior vented exhaust line should end using a Model V145 wall cap. For optimal indoor air quality, exhausting the power unit to the outdoors is recommended but is not required.

Grounding Instructions:

Improper connection of the equipment-grounding conductor can result in a risk of electric shock. This appliance must be grounded. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances. Check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the appliance – if it will not fit the outlet, have a proper outlet installed by a qualified electrician.

Wiring:

The NUTONE NC1500 is for use on a standard 120 VAC, dedicated 15-amp branch circuit with a NEMA 5-15R receptacle. Make sure the power unit is connected to an outlet that has a grounding attachment plug that looks like the one shown in the manual. No adapter should be used. Inlet leads are to be connected to the power unit low voltage tabs using crimp connectors (included in the parts bag) and the low voltage harness.

Open the wall inlet cover and insert the end of the hose into the inlet to turn on the vacuum.

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. The ON/OFF switch located on the power unit needs to be kept in the OFF position.

As you vacuum, dirt and dust are carried to the power unit where they remain in a bag or in the debris pail.

Use the cleaning tools as you would for any other vacuum cleaner. Avoid picking up very large or lengthy debris as these kinds of objects may become lodged in the hose or tubing.

With a 6 U.S. gallons (22.7 liters) capacity, under normal conditions the bag requires changing approximately twice a year. If the bag is full, you will notice a reduced suction from the system. Unless this loss of suction is caused by a blockage, 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.

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

2. Unfold the new bag.

3. Grasp the collar where indicated on the new bag and insert it over the bag adapter. Be careful not to tear the bag. Ensure the collar is positioned between the taper ring and the bag stopper on the bag adapter. Put the pail back in its place.

The NUTONE NC1500 has a motor foam safety filter located at the top of the vacuum chamber. It 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 a replacement bag is installed.

To clean, simply brush the filter clean. If the filter is excessively soiled, hand wash it in a water and mild detergent solution, rinse, and let it dry completely on a flat surface before reinstalling.

CAUTION: Operating the power unit without the motor foam filter will void the warranty.

Removing the Motor Foam Filter:

Remove the debris pail and disposable bag. Lift the center of the wire retaining the motor foam filter and slide the filter out of its location.

Reinstalling the Motor Foam Filter:

To reinstall the filter, reverse the steps described above.

1. Secure the hose hanger to the wall using the 2 provided screws. Depending on the chosen location, you may need to use wall anchors (not included).

2. Wind the hose around its hanger when not in use.

1. Secure the wand hanger to the wall using the 2 included screws. Depending on the wall surface, the use of wall anchors (not included) may be necessary.

2. Push the wand in its hanger when not in use for storage.

Low Voltage Hose:

To ensure proper operation, insert the hose into the wall inlet. Align the tab on the hose up with the depression in the wall inlet (A).

Dual Voltage Hose (Electric Kits Only):

In addition to connecting into the wall inlet (A), the dual voltage hose must also be connected to a standard electrical outlet (B).

Low Voltage Hose:

The switch will turn the power unit ON (I position) and OFF (O position).

Dual Voltage Hose:

• Switch on II position: Central vacuum mode with power brush.

• Switch on I position: Central vacuum mode without power brush.

• Switch on O (center) position: Power unit is turned OFF.

1. Read important safety instructions before installing the power brush.

2. Ensure the hose is disconnected from the power supply before installing the power brush.

3. Push the wand into the power brush neck so that the lock button snaps in place.

4. Connect the hose handle into the wand quick connector and ensure that the prongs are aligned with the receptacle holes. Push until the lock button snaps in place.
