5.2 Aspirazione a umido
For liquids and wet spills:
- Rimuovere il sacchetto filtro. The HEPA filter should be clean and properly seated, or a foam filter (if provided) should be used for wet applications.
- Do not overfill the tank. Monitor the liquid level to prevent overflow.
- Use a suitable wet nozzle.
- After use, turn off the vacuum, unplug it, and empty the liquid from the tank immediately. Clean and dry the tank thoroughly.
5.3 Ash Vacuuming
For cold ashes from fireplaces, stoves, or grills:
- Ensure ashes are completely cold before vacuuming to prevent fire hazards.
- Use the metal hose and crevice tool specifically designed for ash collection.
- Ensure the HEPA filter is clean and properly installed. Some models may include a specialized ash filter.
- Do not vacuum hot embers or glowing materials.
- Empty the tank after each use and clean the filter.

To use the vacuum cleaner as a blower:
- Scollegare il tubo dall'ingresso di aspirazione.
- Connect the hose to the blower outlet, usually located on the motor head.
- Assicurarsi che il serbatoio sia vuoto e pulito.
