Contaminated items:
When carrying out maintenance or repair work, all contaminated items which have not been ad-
equately cleaned must be disposed of. Such items must be disposed of in impermeable bags in
accordance with the applicable regulations concerning the disposal of such waste.
Testing the effectiveness of the vacuum cleaner:
There must be an adequate air exchange rate L in the room if the exhaust air returns to the
room. Further information can be taken from your national regulations. If the suction of the vacu-
um cleaner reduces and the cleaning procedure of the folding filter cassettes increases, the suc-
tion performance is not adequate (provided that the container is empty and the fleece filter bag
has been replaced) then it is necessary to replace the folding filter cassettes.

Cleaning
Acids, alkalis and solvents can corrode the vacuum cleaner parts.
