Setup and Assembly
Before first use, ensure all components are present and undamaged. Refer to the included assembly guide for detailed diagrams.
- Unpacking: Carefully remove all components from the packaging. Retain packaging for future storage or transport.
- Wheel Installation: Attach the wheels to the base of the vacuum unit. Ensure they click securely into place.
- Hose Connection: Insert the flexible hose into the suction inlet on the front of the vacuum unit. Twist to lock it securely.
- Wand and Nozzle Assembly: Connect the metal wand sections together. Attach the desired floor nozzle or accessory to the end of the wand. Connect the other end of the wand to the hose handle.
- Filter and Dust Bag Installation:
- For dry vacuuming, ensure the certified HEPA filter is correctly seated and a synthetic dust bag is installed in the tank.
- For wet vacuuming, remove the dust bag. The HEPA filter can remain, but ensure it is suitable for wet use or remove it if specified by the manufacturer for certain wet applications.
- Power Connection: Plug the power cord into a suitable grounded electrical outlet.
Operating Instructions
Basic Operation
- Power On/Off: Locate the power switch on the top of the vacuum unit. Press to turn the vacuum on or off.
- Dry Vacuuming: Ensure the dust bag is installed and the HEPA filter is clean. Use appropriate nozzles for the surface being cleaned.
- Wet Vacuuming: Remove the dust bag. Ensure the HEPA filter is suitable for wet use or removed if necessary. Do not overfill the tank; monitor the water level. The vacuum is equipped with a float system that will stop suction when the tank is full.
- Exhaust Blow Function: To use the blow function, connect the hose to the exhaust port located on the rear of the vacuum unit. This can be used for blowing away debris or drying surfaces.
Auto-Tool Start Feature
The Aero 26 HEPA features an auto-tool start function, allowing the vacuum to power on automatically when a connected electric power tool is activated.
- Plug the vacuum's power cord into a wall outlet.
- Plug your electric power tool into the integrated power outlet on the vacuum unit.
- Set the vacuum's power switch to the "Auto" or "Tool Start" position (refer to the control panel for specific labeling).
- When you activate the power tool, the vacuum will automatically turn on. When the power tool is turned off, the vacuum will continue to run for a few seconds to clear the hose, then shut off.
- Note: The auto-tool start feature has a power limit. If the connected tool overloads the circuit, the tool may shut down while the vacuum continues to run. Turn the vacuum off and on again to reset.
Push & Clean Filter Cleaning
The Push & Clean system provides semi-automatic filter cleaning to maintain optimal suction performance.
- While the vacuum is running, cover the end of the hose or nozzle with your hand.
- Press and hold the "Push & Clean" button (usually a large button on the top of the unit) for a few seconds. You will hear a change in the motor sound as the filter is vibrated clean.
- Release the button. Repeat if necessary until suction power is restored.
- Perform this procedure regularly, especially when you notice a decrease in suction.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your Nilfisk Alto Aero 26 HEPA vacuum.
Filter Maintenance
- HEPA Filter: The certified HEPA filter should be inspected regularly. While the Push & Clean system helps, the filter will eventually need manual cleaning or replacement. Tap the filter gently to dislodge dust, or rinse with water if it's a washable filter (check manufacturer's instructions for your specific filter type). Ensure it is completely dry before reinstallation.
- Pre-filter (if applicable): Some models may have a pre-filter. Clean or replace as needed.
Dust Bag Replacement
- When the dust bag is full, suction power will decrease.
- Unplug the vacuum from the power outlet.
- Open the latches and remove the motor head.
- Carefully remove the full dust bag, sealing the opening to prevent dust escape.
- Dispose of the bag according to local regulations, especially if collecting hazardous materials like drywall dust.
- Install a new synthetic dust bag, ensuring it is properly seated in the tank.
- Replace the motor head and secure the latches.
Tank Cleaning
- After wet vacuuming, empty and rinse the tank thoroughly to prevent mold and odors.
- Allow the tank to air dry completely before storing or switching back to dry vacuuming.
General Care
- Wipe down the exterior of the vacuum with a damp cloth. Do not use harsh chemicals.
- Inspect the hose, wand, and accessories for blockages or damage. Clear any obstructions.
- Check the power cord for any cuts or fraying. If damaged, have it replaced by a qualified technician.
- Store the vacuum in a dry, protected area. Utilize the built-in storage for the hose and accessories to keep them organized.
