How to replace the safety drum:

■ Place the hose in a safe, dustfree place;
■ Release the container (I);
■ Close the safety drum with the supplied cover and remove
it from the container (I). Fit an empty drum in its place.
■ Start the motor again to prevent dust from being blown
about.
■ Make sure that the seal is in perfect condition and cor-
rectly positioned.
■ Switch off the motor, fit an empty drum in place and
fasten it in position.

Use as a wet cleaner

Make sure that the vacuum cleaner is equipped with a float
(liquid level sensor) and is suitable for use as a wet cleaner.
Do not clean up flammable liquids.
If foam forms, stop work immediately and empty the container.
The filter element will be wet after liquids have been cleaned
up.
A wet filter element can quickly become clogged if the vacuum
cleaner is then used to clean up dry substances.
For this reason, make sure that the filter element is dry or
replace it with another one before using the vacuum cleaner
to clean up dry materials.

At the end of a cleaning session

1. Turn off the vacuum cleaner and remove the plug from
the socket.
2. Coil the connection flex.
3.
Empty the container as described in the "Emptying the
container" section.
Clean the vacuum cleaner as described in the
"Maintenance, cleaning and decontamination" section.
4. Wash the container with clean water if aggressive
substances have been cleaned up.
5. Store the vacuum in a dry place, out of the reach of
unauthorized people.

6. Shut the inlet with the appropriate plug (A) when
the vacuum cleaner is transported or not being used
(particularly in the case of versions M - H and Asbestos).

Maintenance, cleaning and
decontamination
The precautions described below must be taken
during all the maintenance operations, including
cleaning and replacing of the filter.
■ To allow the user to carry out the maintenance
operations, the vacuum cleaner 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.
The external parts of class H and class M
■
appliances 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 appliance must be considered
as contaminated when they are removed from the
hazardous zone and appropriate actions must be
taken to prevent dust from dispersing.
When servicing work or repairs are carried out,
all the contaminated elements that cannot be
cleaned well must be eliminated.
These elements must be disposed of in sealed
bags conforming to the 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 (main, Hepa and downstream
filters).
Compartments that are not dust-tight must be opened
with suitable tools (screwdrivers, wrenches, etc.)
and thoroughly cleaned.
■ Carry out a technical inspection at least once a
year, for example: check the 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.
This inspection must be carried out by the
manufacturer or by a competent person.
Only use genuine spare parts.
