Liquids vacuuming
WARNING!
Make sure that the vacuum cleaner is equipped with a
liquid level sensor and is suitable for vacuum liquids.
■ The lter element will be wet after liquids have been
vacuumed.
A wet lter element can quickly become clogged if the vacuum
cleaner is then used to vacuum dry substances.
For this reason, make sure that the lter element is dry or
replace it with another one before using the vacuum
cleaner for dry materials.
At the end of a cleaning session
■ Turn the vacuum cleaner o with switch (1 - Fig.5) and
disconnect the plug from the socket.
■ Wind the connection cable up and hang it in the relevant
compartment (Fig. 13).
■ 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 persons.
■ Close the inlet with the appropriate plug (1, Fig. 13A)
when the vacuum cleaner is transported or is not being
used (particularly in the case of M, H) versions).
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 maintenance operations, including cleaning
and replacing the primary and absolute lters.
WARNING!
The maintenance, cleaning and
decontamination operations must only
be performed with the vacuum cleaner
turned o 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 ltered
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
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 absolute lters).
Compartments that are not dust-tight must be opened
with suitable tools (screwdrivers, wrenches, etc.) and
thoroughly cleaned.
■ 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 lters to nd out whether the air-tightness
of the vacuum cleaner has been impaired in any way and
make sure the electric control panel operates correctly.
