Maintenance, cleaning and
decontamination
WARNING!
To guarantee the safety level of the vacuum
cleaner, only original spare parts supplied by the
manufacturer should be used.
WARNING!
The precautions described below must be taken
during all the maintenance operations, including
cleaning and replacing of the main and HEPA filters.
WARNING!
The maintenance, cleaning and decontamination
operations must only be performed with the
vacuum cleaner turned off with switch (7 - 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.
■
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.
WARNING!
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.
Cartridge and absolute filter

■
close the bag hermetically;
■
dispose of the filter in accordance with the
laws in force.
WARNING!
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.
WARNING!
Take care not to raise dust when this operation is
carried out. Wear a P3 mask and other protective
clothing plus protective gloves (DPI) suited to the
hazardous nature of the dust collected, refer to the
laws in force.
WARNING!
Reassemble with care to avoid trapping your hands
between the vacuum unit and the container. Use
gloves that provide protection against mechanical
risks (EN 388) with a level of protection CAT. II.
