Maintenance, cleaning and
decontamination
WARNING!
The precautions described below must be taken
during all maintenance operations, including cleaning
and replacing the primary and HEPA lters.
WARNING!
The maintenance, cleaning and decontamination
operations must only be performed with the vacuum
cleaner turned off 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 ltered
ventilation of the exhaust air from the room in which it
is disassembled, cleaning the maintenance area and
suitable personal protection.
■ 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 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 lters are
eliminated (primary and HEPA lters).
Compartments that are not dust-tight must be opened
with suitable tools (screwdrivers, wrenches, etc.) and
thoroughly cleaned.
WARNING!
This vacuum cleaner can be equipped with a
HEPA lter for vacuuming dust hazardous to one’s
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 lter system in place.
Primary and HEPA lter disassembly and
replacement
WARNING!
When the vacuum cleaner is used to vacuum
hazardous substances, the lters become
contaminated, therefore:
■ Work with care and avoid spilling the vacuumed
dust and/or material;
■ Place the disassembled and/or replaced lter in a
sealed plastic bag;
■ Close the bag hermetically;
■ Dispose of the lter in accordance with the laws
in force.
WARNING!
Filter replacement is a serious matter. The lter must
be replaced with one of identical characteristics,
ltering surface and category.
Otherwise the vacuum cleaner will not operate
correctly.
