To properly locate the NUTONE NT700A power unit, follow these guidelines:

• 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, dedicated 15-amp branch circuit.

• 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).

• 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).

Your NUTONE NT700A is factory shipped for cyclonic mode but can be converted to use a disposable bag (model 391C). Follow these steps to install the included bag adapter:

1. Remove the pail from the unit by releasing both side latches, pulling them out and then pushing them up. Detach the pail from the unit.

2. Assemble the bag adapter to the intake elbow. Align the triangle on the adapter with the small inclined stud on the elbow.

3. Tighten the junction using the screw and nut included in the parts bag.

4. Unfold the disposable bag and grasp its collar where indicated. 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 place.

1. 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.

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

3. Hang the power unit onto the wall mounting bracket. Ensure the back brackets of the power unit are engaged with the corresponding wall bracket fingers.

4. Pull the power unit down to secure.

Refer to the illustrations in the user guide for minimum wall, floor, and ceiling clearance dimensions, as well as specific mounting hole measurements.

1. Run the house vacuum line up to the elbow behind the power unit.

2. Insert the end of the line into the elbow opening and secure the house vacuum line by hand tightening the screw and nut provided. DO NOT GLUE.

3. For the NUTONE NT700A, ensure you connect the included utility valve to the intake line in the appropriate way, as shown in the manual’s diagram.

Assemble the exhaust tubing to the exhaust outlet on top of the NUTONE NT700A. DO NOT GLUE.

The coupling or elbow used to connect the exhaust line to the top of the unit may be secured using two 5/8″ included screws.

Note the following:

• Make sure all tubing connections are airtight.

• 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 using a Model V145 wall cap.

• For optimal indoor air quality, exhausting the power unit to the outdoors is recommended but is not required.

To operate your NUTONE NT700A, 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. When using these hoses or the utility valve, 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.

With a 6 U.S. gallons (22.7 liters) capacity, under normal conditions the bag/debris pail on your NUTONE NT700A requires changing or emptying approximately twice a year. If the bag/debris pail is full, you will notice a reduced suction from the system. Unless this loss of suction is caused by a blockage in the system, changing the bag or emptying the debris pail 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.

To empty the debris pail on your NUTONE NT700A when operating in cyclonic (bagless) mode, follow these steps:

1. Release both latches on the sides of the unit by pulling them out and then pushing up.

2. Holding the pail by the latches, lower it from the unit.

3. Carry the pail to a trash receptacle and dispose of the debris.

4. Put the pail back in its place.

1. To remove the old bag, release both latches on the sides of the unit by pulling out and then pushing up. Remove the pail from the unit.

2. Grasp the edges of the bag collar and pull down. The bag will slide off easily. Do not pull on the bag itself.

3. Unfold the new bag.

4. 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 permanent filter on your NUTONE NT700A protects the motor during cyclonic (bagless) operation. Under normal use, it does not need maintenance. If you need to remove it for inspection or replacement, follow these steps:

Removal:

1. Remove the pail from the unit.

2. To remove the permanent filter, use the pull tab (A) located on the edge of the filter to pull and loosen the filter from the inlet chamber wall.

3. Squeeze from both sides of the filter to the center of the housing. Then, carefully remove it from the unit.

Reinstallation:

1. Squeeze the filter in order to move it past the inlet opening.

2. Let the filter bear against the unit wall by releasing the pressure.

3. Make sure to place the rigid ring in its groove to ensure proper sealing.

NOTE: Make sure the filter is installed so that the pull tab (A) is accessible for future filter removal. Be sure to reinstall the filter properly as its location is critical to insure proper protection of the motor.

The motor foam safety filter provides protection against dirt being pulled into the motor. It should be checked and cleaned when a replacement bag is installed or when the permanent filter is removed. Operating the power unit without the motor foam filter will void the warranty.

To remove the filter:

1. Remove the debris pail and disposable bag or permanent filter.

2. Lift the center of the wire retaining the motor foam filter and slide the filter out of its location.

Cleaning and Reinstallation:

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. To reinstall the motor foam filter, reverse the removal steps.

The NUTONE NT700A comes with the NTAIRKIT1 accessory kit, which includes:

1. Deluxe combo floor brush

2. Standard floor brush

3. Mesh storage bag

4. Low-voltage hose, 35 ft. long

5. Hose sock

6. Hose hanger

7. Telescopic wand for static tools

8. Round dusting brush

9. Mini air turbine

10. Long crevice tool

To ensure proper operation of the low voltage hose included with your NUTONE NT700A, insert the hose into the wall inlet. Align the tab on the hose end up with the depression in the wall inlet (A).

The switch on the handle of your NUTONE NT700A low voltage hose will turn the power unit ON (I position) and OFF (O position).

If you experience a loss of suction with your NUTONE NT700A, check the following possible causes and remedies:

• Debris pail or disposable bag is completely full.

  Empty the debris pail or change the disposable bag as described in the manual.

• Debris pail gasket damaged or missing.

  Replace the debris pail gasket.

• Obstruction in the hose.

  To check, insert the hose into any wall inlet and check other inlets for normal suction. If suction is normal elsewhere, the blockage is in the hose. Disconnect the hose and insert a blunt instrument (like a garden hose) to push the obstruction through until it has been cleared.

• Obstruction in the tubing system inside the walls.

  Insert the hose end into any inlet to make the power unit run, then place the palm of your hand over the opposite end of the hose. When you feel suction increase, hold your hand over the end for a few seconds and then quickly remove it. Repeat this several times to clear the obstruction. If not cleared, contact a Service Center.

• Permanent filter or disposable bag torn.

  Clean the interior of the unit and install a new permanent filter or disposable bag.

• Wall inlet cover not properly sealed.

  Check all wall inlet covers to be sure they are closed and sealed tightly.

• Exhaust tubing or vent clogged.

  Inspect and remove any blockages.

If your NUTONE NT700A fails to start or stops unexpectedly, consider these potential issues:

• Defective inlet.

  Check other wall inlets. If they work, replace the defective wall inlet.

• Power unit internal circuit breaker has been activated.

  Push on the circuit breaker reset button located on the left side of the power unit. If this button pops up again, contact your authorized Service Center.

• Blown fuse or tripped circuit breaker on house electrical panel.

  Replace the fuse or reset the circuit breaker. Ensure the circuit is DEDICATED to the central vacuum unit. If you have sensitive breakers (e.g., Square D brand), consider changing the breaker to an “HM” type of the same AMP rating.

• Defective hose.

  Replace the hose as required.

• Power unit overcurrent protector has been activated.

  Unplug the power unit, wait at least 15 minutes, and plug the power unit back in.

If your NUTONE NT700A continues to run after the hose is removed, check these possible causes:

• The unit power switch is in the ON position.

  Set the unit power switch to the OFF position.

• An electrical short has occurred somewhere in the system.

  Perform a complete check of all wall inlets and power unit low voltage control lead connections. Contact your authorized Service Center.
