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).

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

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

2. For HHKIT550E models: 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 HHKIT550E models: Using a Phillips screwdriver no. 2, remove the screw tightening the bag adapter and intake elbow junction. Disassemble the bag adapter from the intake elbow and set 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 at its original position. NOTE: Ensure the gasket is not folded in order to prevent lack of suction, and noise.

6. For HHKIT550E models: Reassemble the bag adapter to the intake elbow. Align triangle with small inclined stud, then tighten the junction using the screw and nut previously removed in step 3.

7. For HHKIT550E models: Put the bag back in place by grasping the edges of its collar and 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.

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

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

2. Refer to clearance dimensions to maintain minimum wall and floor clearances: 12″ minimum from side walls, 12″ minimum from ceiling, and 18″ minimum above the floor.

3. Position and install the wall mounting bracket with the provided screws. The bracket has an overall height of 32 7/8 inches with upper and lower mounting holes. A minimum height of 45 1/4 inches is required. CAUTION: 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 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 the house vacuum line by hand tightening the screw and nut provided from the parts bag. DO NOT GLUE.

2. 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.

WARNING: 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.

Grounding Instructions: 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 manual illustrations. No adapter should be used with this power unit. Inlet leads are to be connected to power unit low voltage tabs using crimp connectors (included in parts bag) and 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.

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 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 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.

1. To remove the disposable bag, release both latches on the sides of the unit by pulling 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.

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 should accidentally be torn. This filter should be checked and cleaned if necessary when a replacement bag is installed. 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 motor foam filter, reverse the steps described above.
