Cutting Tubing

Measure the length of tube needed. Allow 5/8″ of tubing for inserting into fittings. Cut the plastic tubing with a hacksaw, ensuring that the cut is exactly square. Use a small knife or steel wool to remove any burrs from the inside of the tube. Use a file to slightly bevel the outside of the tube so that it will easily slide into the fitting. Use steel wool or a light grained sandpaper to buff the surface of the tube which will be glued.

Making a Joint

Insert the tube into the fitting, aligning both parts as they will be installed. Mark the tube and the fitting to quickly realign the joint. Apply cement in an inch-wide band to the outside of the tube. Insert the tube into the fitting with the alignment marks a quarter turn apart, and then quickly push and turn the fitting to align the marks and spread the cement. Allow 1 minute for the joint to dry.

Securing Wire to Tubing

The low-voltage power wiring is run along with the tubing. Use electrical tape to secure the wire to the tubing. Tape the wire 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 and locate the inlet tubing. Pull the flexible tubing through the inlet hole and remove the low-voltage wiring from inside the tube. Remove the nail flange from the inlet mounting plate. Apply cement to both the inside of the flexible tubing and to the outside of the mounting plate’s tube ring. Insert the mounting plate’s tube ring in the flexible tubing, twisting the pieces as you join them to spread the cement, and align the mounting plate in a vertical position. Strip the ends of the two low-voltage wires, and then connect the wires to the screw terminals on the back of the inlet cover.

3. Completing the Inlet Assembly

Once you have attached the mounting plate to the flexible tubing, 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 (the inlet cover remains on the outside). Hold the inlet in place and gradually tighten down each screw a little bit at a time.

Follow these guidelines for locating your 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, 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).

• Do not install outdoors. Before being hung, rest the unit on a leveled surface to prevent the unit from falling down.

The NUTONE HHKIT650A unit is factory shipped ready for use in cyclonic mode, but due to its hybrid design, it can also be operated with a disposable bag (391C). The bag adapter (included with the unit) must be installed if the disposable bag will be used. Follow these steps:

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

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

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

4. Unfold the disposable bag and grasp its collar where indicated. Insert over 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. Maintain Clearances: Refer to the diagrams in the user guide to maintain minimum wall and floor clearance dimensions. You need 12″ minimum clearance on the sides, 12″ minimum from the ceiling, and 18″ minimum above the floor.

2. Install Mounting Bracket: 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. Use the provided mounting screws to secure the bracket through the upper and lower mounting holes. The minimum height for the bracket is 45 1/4″.

3. Hang the Power Unit: 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. Pull the power unit down to secure.

Fitting Main Line to Power Unit:

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 the house vacuum line by hand tightening the screw and nut provided. DO NOT GLUE.

Assembling Exhaust Tubing:

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

NOTE: Using flexible tubing will ease future top cap removal.

NOTE: Make sure all tubing connections are air tight.

NOTE: 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. Exterior vented exhaust line should end using Model V145 wall cap.

NOTE: 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. 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.

This appliance must be grounded. If it should malfunction or break down, grounding provides a path of least resistance for electric current, to reduce the risk of electric shock. This appliance is equipped with a cord having an equipment-grounding conductor and grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Wiring:

This appliance is for use on a standard 120 VAC, dedicated 15-amp branch circuit with a NEMA 5-15R receptacle. Make sure that the power unit is connected to an outlet and has a grounding attachment plug that looks like the plug shown in the illustration. No adapter should be used with this power unit.

Inlet leads are to be connected to the power unit’s 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 (according to the power unit model).

Use the cleaning tools as you would for any other vacuum cleaner. Avoid picking up very large debris or lengthy items 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/debris pail requires changing/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, release both latches on sides of the unit by pulling out and then pushing up. Holding the pail by the latches, lower it from the unit. Carry the pail to a trash receptacle and dispose of the debris. Put the pail back in its place.

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 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.

Permanent Filter

This filter protects the motor and stops small particles from escaping. It cleans itself by moving up when the power unit starts and dropping down when the unit is turned off. Under normal use, there is no need to maintain this filter. It can be removed to inspect the motor foam filter or to be replaced if damaged.

To remove the filter:

1. Remove the pail from the unit. Use the pull tab (A) on the edge of the filter to pull and loosen it from the inlet chamber wall.

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

3. To reinstall, squeeze the filter to move it past the inlet opening. Let the filter bear against the unit wall by releasing pressure. Ensure the rigid ring is in its groove for proper sealing. Make sure the pull tab is accessible for future removal.

CAUTION: Be sure to reinstall filter properly. Appropriate location is critical to insure proper protection of the motor.

Motor Foam Filter (All Units)

A motor foam safety filter, located at the top of the vacuum chamber, provides protection against dirt being pulled into the motor if the disposable bag or permanent filter should accidentally be torn. This filter should be checked and cleaned if necessary when a replacement bag is installed, or when the permanent filter is removed. 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.

Installing the Hose Hanger:

Secure the hose hanger to the wall using the 2 provided screws. Depending on the chosen location, wall anchors (not included) may be necessary. Wind the hose around its hanger when not in use.

Connecting the 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).

Operating the Handle Switch:

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

If you experience a loss or decrease of suction, check the following possible causes and remedies:

• Possible Cause: Debris pail or disposable bag is completely full.

Remedy: Empty the debris pail or change the disposable bag.

• Possible Cause: Debris pail gasket is damaged or missing.

Remedy: Replace the debris pail gasket.

• Possible Cause: Obstruction in the hose.

Remedy: Disconnect the hose from the wall inlet and insert a blunt instrument (like a flexible garden hose) through the cleaning system hose until the obstruction has been cleared.

• Possible Cause: Obstruction in the tubing system inside the walls.

Remedy: 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 the suction increase, hold your hand over the hose end for a few seconds and then quickly remove your hand. Repeat this procedure several times to clear the obstruction. If not cleared, contact your nearest Service Center.

• Possible Cause: Permanent filter or disposable bag is torn.

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

• Possible Cause: Wall inlet cover is not properly sealed.

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

• Possible Cause: Exhaust tubing or vent is clogged.

Remedy: Inspect and remove any blockages.

If your power unit does not start or stops suddenly, check these possible causes and remedies:

If your power unit runs continuously when the hose is removed, check these possible causes and remedies:

• Possible Cause: The unit power switch is in the ON position.

Remedy: Set the unit power switch to the OFF position.

• Possible Cause: An electrical short has occurred somewhere in the system.

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