1.7 Permitted Uses
These vacuum cleaners are designed and built according to the 2014/34/EU
(ATEX) Directive for an exclusive professional industrial use; either way,
for any non-domestic use,
This vacuum cleaner is suitable for the cleaning and the
collection of solid materials, only in covered areas. This
vacuum cleaner is designed to collect combustible dust and/or
dry particles in Zone 21 and Zone 22 (for atex vacuums only )
classified atmospheres with the following limitations:
Minimum ignition energy (MIE) of dust > 3mJ
The vacuum cleaner was conceived to be used by only one operator.
In accordance with the Directive 1999/92/EC, whenever in the presence of
combustible dust and/or flammable gas, it’s the responsibility of the
employer to carry out the classification of the Zone and to choose a device
in the appropriate category (According to the definition given in the
2014/34/EU Directive.
Do not use the vacuum cleaner to remove chemically unstable dust
Any other use is considered IMPROPER.
1.8 Authorised environmental conditions
To ensure the correct operation, the vacuum cleaner must be kept away from
atmospheric agents (rain, hail, snow, fog, dust in suspension, etc.) in an
area with a room temperature range between 5° and 45°C and a relative
humidity no higher than 70%.
The work environment must be clean and suitably lit.

2. SAFETY SECTION
2.1 Safety Information
As per Italian Legislative Decree 81/08 and subsequent
modifications, the Safety Manager must train and inform workers
about the risks involved with using the vacuum cleaner so that
they may be able to avoid injury to themselves and others.
The use of device by people (including children) with limited physical and
mental capacities or lacking in experience and knowledge is strictly
forbidden, unless they are supervised by a person who is experienced in the
use and safe handling of the device.
Children must be supervised to make sure they will not play with the device.
Failure to comply norms, laws or basic safety precautions, may cause
accidents during operation, maintenance and repair of the vacuum cleaner.
Accidents can frequently be avoided by recognising potentially hazardous
situations before they occur. Adequate training is crucial to this end.
DEPURECO shall not be held liable for accidents or damage due to the
improper use of the vacuum by untrained personnel or to failure to comply,
even partially, with the occupational safety standards and intervention
procedures contained in this manual.
Safety warnings and precautions are indicated in this manual as well as on
the product itself.
Operators must pay special attention to these hazard warnings to prevent
accidents with serious consequences for themselves and other people.
The safety warnings are indicated by the following symbols:
DEPURECO designs and manufactures its equipment and accessories with care,
identifying and compensating possible risks related to their use. In the
event of equipment, procedures, work methods or techniques not expressly
provided for by DEPURECO being used, it is crucial to ensure beforehand that
there are no dangers for oneself and the others. Nevertheless, DEPURECO
shall not be held liable.
Use exclusively Depureco original spare
parts.
Depureco disclaims any liability in case
spare parts other than original have been
used.

2.2 Safety recommendations
WARNING!
The following information is essential in view of preventing all
hazards that may occur while the vacuum cleaner is running.
However, they cannot replace the expertise and common sense of
operators as an overall framework for the prevention of accidents.
Structural damage, alterations or improper repairs can modify the
protective capacity of the vacuum, thereby nullifying this
certification and releasing DEPURECO from any liability.
Each section lists further safety measures specific to the various
functions.
WARNING!
Setting to work –connection to the power supply
Make sure there is no evident sign of damage to the vacuum cleaner
before starting work.
Before connecting the power outlet, make sure that the ILME socket
is positioned properly (for vacuum cleaners fitted with an air
counterflow cleaning system). Carry out the connection in a safe
area, where there are no explosive atmospheres.
Before plugging the vacuum cleaner into the electrical mains, make
sure the voltage rating
indicated on the data plate corresponds to that of the electrical
mains.
Plug the vacuum cleaner into a socket with a correctly installed
ground contact/connection.
Make sure that the vacuum cleaner is turned off.
The plugs and connectors of the connection cables must be protected
against splashes of
water.
Check that the vacuum cleaner is properly connected to the
electrical mains.
Make sure that the earthing clamp is properly connected to a point
for which continuity with the earthing system is guaranteed.
Use the vacuum cleaner only when the cables that connect to the
electrical mains are in perfect condition (damaged cables could
lead to electric shocks!).
Regularly check there are no signs of damage, excessive wear,
cracks or ageing on the electric cable.
WARNING!
When the vacuum cleaner is operating, do not:
Crush, pull, damage or tread on the cable that connects to the
electrical mains.
Only disconnect the cable from the electrical mains by removing the
plug (do not pull the
cable).
Only replace the electric power cable with one of the same type as
the original: H07 RN - F. The same rule applies if an extension is
used.
The cable must be replaced by the manufacturer’s Service Centre
staff or by equivalent qualified personnel.

Page 16 of 48
CAUTION!
It is absolutely forbidden;
•For underage and non-trained people to use this vacuum cleaner.

accessories: The resistance measured must be inferior
to 100MΩ (108 Ω)
2. Between the bin and the plug (ground pin) with an
electric device, or between the bin and the earthing
cable (supplied) with compressed air powered devices.
The resistance measured must be less than 10 Ω

4. Flammable, combustible or aggressive liquids
(gasoline, solvents, acids, alkaline solutions etc…)
5. Dusts/Substances and/or spontaneously combusting
explosive mixtures of them (magnesium or aluminium
dusts etc…)
•To tamper with or modify the return valve set up by the manufacturer
•The use of the JETCLEAN system in the presence of potentially explosive
clouds in the atmosphere.
•To carry out maintenance on the vacuum cleaner in ATEX classified areas
•To carry out maintenance on the vacuum cleaner without first having
switched the device off and disconnected the plug from the socket.
•To keep foreign materials such as debris, oil, tools or other objects in
the bin which could disrupt the functioning and cause harm to people.
•To use flammable or toxic solvents such as gasoline, benzene, ether or
alcohol for cleaning.

the manufacturer.

Page 17 of 48
•To operate the vacuum cleaner without safety devices.
•To wear loose or flowing apparel such as ties, scarves, or torn clothing
that could get caught on the vacuum cleaner or vacuumed by the device.
•To open the waste bin while the vacuum cleaner is working.
•To open the waste bin in an area which has been classified potentially
explosive.
•To use extension leads, plug-in connection devices and adapters.
•To climb on the vacuum cleaner.
•To touch electrical wires, switches, buttons, etc. with wet hands.
•To touch some components which could reach high temperatures (such as the
motor’s terminal box and the motor housing in particular) while operating
the vacuum cleaner.
WARNING!
This vacuum cleaner could contain dust that may be hazardous to your
health.
The emptying out and maintenance procedures, including removing the
dust containers, must be carried out exclusively by specialized
personnel wearing suitable safety clothing.
Never switch the machine on in the absence of a complete filtering
system.
2.3 Safety plates and symbols
Plates with safety symbols and/or messages are applied to the vacuum and its
packaging.
These pages show their precise location and the nature of the hazard.
Warning!
Ensure that all safety messages are perfectly legible.
Clean them using a cloth with water and soap. Do not use solvents,
naphtha or petrol.
Request replacements for damaged plates from DEPURECO.
If a plate is located on a component that is being replaced, make sure
to fit the old plate to the new component.
