■ A check must be carried out by the manufacturer or the
personnel of the same at least once a year. For example:
Check the air filters to find out whether the air-tightness
of the vacuum cleaner has been impaired in any way
and make sure that the electric control panel operates
correctly and the proper functioning of the vacuum gauge
whose needle should indicate the red zone by closing the
inlet.
In particular, on Class H vacuum cleaners, the filtering
efficiency of the vacuum cleaner must be checked at
least once a year, or more often if required by national
legislation. The test method for checking the filtering
efficiency of the vacuum cleaner is indicated in
standard EN 60335-2-69, par. AA.22.201.2.
If the test isn't passed, it must be repeated after the
class H filter has been changed.
Primary and absolute filter disassembly
and replacement
When the vacuum cleaner is used to vacuum
hazardous substances, the filters become
contaminated, therefore:
■ work with care and avoid spilling the vacuumed
dust and/or material;
■ place the disassembled and/or replaced filter in a
sealed plastic bag;
■ close the bag hermetically;
■ dispose of the filter in accordance with the laws
in force.
Filter replacement is a serious matter. The filter must
be replaced with one of identical characteristics,
filtering surface and category.
Otherwise the vacuum cleaner will not operate
GB
correctly.
