EN 1127-1 - EN ISO 80079-36 - EN IEC 60079-0 - EN IEC
60079-31 EN 60079-14
Observe the prescriptions of the above standards
They are designed to be used in areas classified as Zone 22
and Zone 2.
Never use the vacuum cleaners in Zones 20, 21 and/or Zone
0 or 1.
These vacuum cleaners are designed to vacuum occasionally
dust and/or wet and dry particles in atmospheres classified as
Zone 22 or Zone 2, to clean places and machines, especially in
the foodstuff, chemical, pharmaceutical and textile industries.
They are not designed to be used for ST3 explosion class
dust, that is to say dust with value of Kst > 300 bar m/s
(ISO 6184/1 – IFA classification: http://staubex.ifa.dguv.
de/?lang=e), nor dust with an ignition energy lower than
1 mJ. For these applications please refer to paragraph
G - Additional prescriptions for models equipped with
immersion separator.
They are not designed to collect explosives or chemically
unstable substances.
I
They are not designed to vacuum fluids with a low flash point
(Flash Point lower than 55°C), nor for incendiary substances
(T < 200 °C).
GB
For these models, apart from following the instructions in the
use and maintenance manual of the standard vacuum cleaner,
F
specific precautions and maintenance are also required.

(Jet Fuel).
Only vacuum cleaners with IP6X protection class
are suitable to collect conductive combustible dust
(e.g. metallic):
II3D Ex tc IIIC T125°C Dc IP65
for Zone 22 (conductive dust: IP 65)
See marking example in paragraph I.
Check the electric panel and the grommets (Pg) for integrity, to
prevent dust infiltrations.
Check that the hose clamps are correctly tightened.
In case of breakage, only use original Nilfisk spare parts.
Any parts that need replacing must be replaced by trained
personnel. Never perform any kind of disassembly, tampering
and/or maintenance on the safety systems.
The motor and turbine ball bearings and the protective filter
of the safety valve must be serviced by a Nilfisk Service
Center every 10,000 working hours or every 2 years.
Contact the sales network or the machine manufacturer.
The operator must not dismantle, tamper with and/or
service the turbines.
Vacuum unit corrosion can be a real danger. The vacuum units
of these machines are made of aluminium alloy. Do not vacuum
gases, vapours and/or fluids that can corrode aluminium alloys.
In the case of abnormal noise, faulty bearings or faulty
rotating parts, stop the machine immediately, as there
is the risk of explosion!
Repairs must be done by Nilfisk Service Centers only.
Periodically clean the motor cooling fan to prevent the motor
from overheating.
All the above prescriptions, precautions and service
operations must be observed, or the Nilfisk Warranty for
proper operation of ATEX machine will become void, the
Nilfisk ATEX Declaration of Conformity will no longer be
valid and the User will be entirely responsible for the use
of the vacuum cleaner.
All maintenance and cleaning operations must be
carried out when the machine is off and disconnected
from the electrical mains.
