• This wet/dry vacuum cleaner is designed to remove dry dirt and liquids.

• The device is suitable for vacuuming dry, conductive, combustible dusts in zone 22 dust class H.

• The device is not suitable for extracting metallic dusts that lead to hydrogen formation on contact with water.

• Type 22 devices are suitable for holding combustible dust in zone 22. They are not suitable for connection to dust-generating machines.

• Type 22 devices are not suitable for the intake of dusts or liquids with high risk of explosion and for mixtures of combustible dusts with liquids.

• The vacuum cleaner is intended for the removal of combustible dusts in potentially explosive environments classified as Zone 22.

• This device is suitable for commercial use,e.g. in production areas in industry and crafts, in warehouses, in transport and in agriculture.

• Any other use will be regarded as improper use.

• The electrical connection (mains plug) must be made outside the hazardous area (Zone 22).

• The included accessories are electrically conductive. Only the accessories listed in the appendix (standard accessories / special accessories) may be used!

• Do not vacuum without filter elements in place, otherwise the suction motor will be damaged and there will be a health risk due to increased fine dust emissions!

• Observe the safety regulations for the materials being vacuumed. During proper/improper operation, parts (e.g. air outlet) of the vacuum cleaner can reach up to 105 °C.

• The minimum ignition temperature (MIT) of the dust cloud is ≥160 °C and the MIT of dust with a dust thickness of 5 mm is ≥180 °C.
