At the end of a cleaning session

■ Turn off the vacuum cleaner and remove the plug from
the socket.
■ Wind the connection cable around the handle (Fig. 14).
■ Empty the container as described in the "Emptying the
container" paragraph.
■ Clean the vacuum cleaner as described in the paragraph

"Maintenance, cleaning and decontamination".

■ Wash the container with clean water if aggressive
substances have been vacuumed.
■ Store the vacuum cleaner in a dry place, out of reach of
unauthorized people.
■ Shut the inlet with the appropriate plug (1, Fig. 14) when
the vacuum cleaner is transported or not being used
(particularly in the case of M, H versions).
Maintenance, cleaning and
decontamination
To guarantee the safety level of the device, only
original spare parts supplied by the manufacturer
should be used.
The precautions described below must be taken
during all the maintenance operations, including
cleaning and replacing of the main and HEPA filters.
■ To allow the user to carry out the maintenance
operations, the device must be disassembled, cleaned
and overhauled as far as is reasonably possible,
without causing hazards for the maintenance staff
or other people. The suitable precautions include
decontamination before disassembling the device,
adequate filtered ventilation of the exhaust air from
the room in which it is disassembled, cleaning of the
maintenance area and suitable personal protection.
■ If the vacuum cleaner belongs to the M or H class, the
external parts 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 device must be considered as
GB
contaminated when they are removed from the
hazardous zone and appropriate actions must be taken
to prevent dust from dispersing.
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 in
accordance with applicable regulations and local laws on
the disposal of such material.
This procedure must also be followed when the filters are
eliminated (main, HEPA and downstream filters).
Compartments that are not dust-tight must be opened
with suitable tools (screwdrivers, wrenches, etc.) and
thoroughly cleaned.

WARNING!
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 that 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.
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.
