1. Dry Extraction
Only extract with a dry fi lter, unit and accessories so that the dust does not adhere and harden. We recommend using a paper fi lter bag if soot, cement,
plaster, fl our or similar substances are extracted. Always use the paper fi lter bag in combination with the fi lter cartridges.
2. Wet Extraction
Extract without a paper fi lter bag. The fi lter cassettes are suitable for wet extraction. The installed sensor switches the motor off when the tank is full.
Empty the unit as outlined in Section 4.
The unit will only be ready for operation again after it has been switched off and switched on again.
- Before emptying, fi rst remove the extraction hose from the liquid.
- Due to the high extraction output and the streamlined shape of the tank, a little water may escape from the hose after the unit has been switched off .
- For the subsequent dry extraction phase, use a dry fi lter. In case of frequent changes between dry and wet extraction, we recommend using a second fi lter set,
preferably polyester fi lter cassettes.
3. Cleaning the fi lter
The extraction unit is fi tted with an electro-magnetic fi lter cleaning device which can shake off any dust adhered to the folded fi lter cassettes.
