4. Installation & Setup
4.1 Central Unit Mounting
Mount the central vacuum unit in a suitable location, such as a garage, utility room, or basement. Ensure the location is dry, well-ventilated, and provides easy access for maintenance. The unit should be securely fastened to a wall stud or appropriate support structure.
4.2 Connecting to Inlets
The Nadair 655 AW system is compatible with most existing central vacuum inlets. Ensure your inlet meets the following criteria:
- The inlet must have 2 pins inside for electrical connection.
- The inside diameter of the inlet must be 1 1/2 inches.
Connect the central vacuum piping from your existing inlet system to the central unit's intake port. Ensure all connections are sealed properly to prevent suction loss.

4.3 Filter Installation (Hybrid Filtration)
The system offers hybrid filtration. You can choose to use it with or without disposable bags. A permanent machine washable filter is included and should always be in place.
- With Disposable Bags: Insert a disposable bag into the canister, ensuring it is properly seated around the intake opening. This method provides cleaner disposal and extends the life of the permanent filter.
- Without Disposable Bags: Ensure the permanent washable filter is correctly installed. Debris will collect directly in the canister.
Refer to the maintenance section for details on filter cleaning and bag replacement.
4.4 Hose and Accessory Connection
Connect the 30ft high-voltage hose to any compatible central vacuum inlet. The hose features a pigtail with a 12-inch power cord for connection to a standard electrical outlet, providing power to the accessories. The swivel at the handle helps prevent kinking during use.
Attach the desired cleaning tool (powerhead, floor brush, etc.) to the telescopic wand, and then connect the wand to the hose handle. For the electrical carpet beater, ensure the adjustable electrical wand is connected to the 2-pin connector on the powerhead.
5. Operating Instructions
5.1 Powering On/Off
Once the hose is connected to an inlet and the pigtail is plugged into an electrical outlet, the central vacuum system can be activated using the On-Off switch located on the hose handle. The system features Soft-Start/Stop Technology, which adds 20% to the life expectancy of the motor by gradually increasing and decreasing power.

5.2 Using the Electrical Carpet Beater (Powerhead)
The electrical carpet beater features 5 adjustable height settings, making it ideal for various carpet types, including shag carpets. It also includes an LED light to illuminate the cleaning path.
- Adjust the height setting using the control on the powerhead to match your carpet pile.
- Ensure the electrical wand is securely connected to the powerhead for power transmission.

5.3 Using the 12-inch Floor Brush
The 12-inch Horsehair Deluxe Floor Brush is designed for effective cleaning of hard surfaces such as tiles, hardwood, stone, concrete, vinyl, and linoleum. Its pivoting neck and double swivel technology allow it to reach tight and difficult-to-vacuum spots without scratching floors.

6. Maintenance
6.1 Emptying the Canister
The 5.8-gallon (22-liter) spun aluminum bottom-load canister should be emptied regularly, depending on usage. To empty, unclip the canister from the main unit and dispose of collected debris. Reattach securely after emptying.

6.2 Filter Cleaning and Replacement
The permanent machine washable filter should be cleaned periodically to maintain optimal suction and system performance. Remove the filter, shake off loose debris, and wash it with water. Allow it to dry completely before reinstallation.
If using disposable bags, replace them when full. Using disposable bags is recommended as it simplifies maintenance and helps keep the permanent filter cleaner.
