ATEX
E - Additional prescriptions for ATEX machines with motor belt
The following models are suitable for vacuuming aircraft fuel (Jet
Nilfisk Models:
CTT series motor + turbine belt drive system
Standards of reference:
These machines comply with EN 1127-1 - EN 60079-0 - EN
60079-31 - EN ISO 80079-36 - EN 60079-14 - IEC TS 60079-
46 Standards
Observe the prescriptions of the above standards.
These machines have been designed to work in areas with
explosive atmosphere. These areas are classified as Zones
21 and 22 (dusty environments), Zones 1 and 2 (areas with
a presence of gas) and Zones Z1/21 and Z2/22 (areas with a
presence of both dust and gas).
Never use the vacuum cleaners in Zone 20 and/or 0 (areas
with Flammable gases).
These vacuum cleaners are designed to vacuum dry and
wet particles and clean places and machines, especially in
food, chemical, pharmaceutical, textile industries, and they
are suitable for collective use in hotels, schools, hospitals,
factories, shops, offices and residences.
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
I
immersion separator.
These are not intended for vacuuming incendiary substances
GB
(T < 200 °C).
For these models, apart from following the instructions in the
F
use and maintenance manual of the standard vacuum cleaner,
specific precautions and maintenance are also required.

Fuel).
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 transmission
belt 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.
This machine has an antistatic transmission belt. In case of
breakage, only use original Nilfisk spare parts. Any parts that
need replacing must be replaced by trained personnel. Adjust
the belt tension so the belt stretches by 1% (e.g. measured on
a 100 mm long belt section – see fig. 1 and 2).
Turbine corrosion can be a real danger. The turbines of these
machines are made of aluminium alloy and galvanized steel.
Do not vacuum gases, vapours and/or fluids that can corrode
these metals.
Depending on the quantity of dust present in the area or, in
any case, every six months, clean the motor plate regularly so
as to remove any dust deposit. Check the transmission belt
tension and wear and, if necessary, replace it with an original
spare part.
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.
