Maintenance, cleaning and
decontamination
To guarantee the safety level of the vacuum cleaner,
only original spare parts supplied by the manufacturer
should be used.
The precautions described below must be taken
during all maintenance operations, including cleaning
and replacing the primary and absolute filters.
The maintenance, cleaning and decontamination
operations must only be performed with the vacuum
cleaner turned off with switch (1 - Fig.5) and the plug
disconnected from the power socket.
It is absolutely forbidden to perform maintenance with
the plug connected to the socket.
Danger of electric shock!
■ If the user is performing the maintenance operations,
the vacuum cleaner must be disassembled, cleaned
and overhauled as far as reasonably possible without
hazards for the maintenance personnel or other people.
The suitable precautions include decontamination before
disassembling the vacuum cleaner, adequate filtered
ventilation of the exhaust air from the room in which it
is disassembled, cleaning the maintenance area and
suitable personal protection.
The external parts of class M and class H vacuum
■
cleaners must be decontaminated by cleaning and
vacuuming methods, dedusted or treated with sealant
before being taken out of a hazardous zone.
All parts of the vacuum cleaner must be considered
contaminated when they are removed from the
hazardous zone and appropriate actions must be taken
to prevent the dispersion of dust.
When maintenance or repair procedure are carried out,
all the contaminated elements that cannot be properly
GB
cleaned, must be eliminated.
These elements must be disposed of in sealed bags
conform to applicable regulations and in accordance with
the local laws governing the disposal of such material.
This procedure must also be followed when the filters are
eliminated (primary and absolute filters).
Compartments that are not dust-tight must be opened
with suitable tools (screwdrivers, wrenches, etc.) and
thoroughly cleaned.

WARNING!
■ 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 the electric control panel operates correctly.
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.
This vacuum cleaner can vacuum dust hazardous for
the health. The procedures for servicing and emptying
the vacuum cleaner including removing the dust
container, must only be performed by specialised
personnel wearing protective clothing. Do not use
without the complete filter system in place.
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
correctly.
