Atex
Do not use plastic bags for the container (only original antistatic
plastic bags are allowed, Nilfisk code "Z01723502 - Z01769505
- 4084001313 - 4084001340").
If a preseparator must be used, check that it is well grounded.
Only use antistatic hoses, both for vacuuming and connecting
the preseparator. Do not use the machine to suck up large
objects or particles because their collision may cause sparks.
Do not rub or hit the floor with steel tools, as they can produce
sparks under friction. Only use collectors and suction caps that
can be replaced with original Nilfisk antistatic spare parts to
clean the floor.
Check the vacuum indicator periodically, to prevent the filter
from clogging.
Bring the vacuum cleaner out of the ATEX classified area, then
release the container and empty it, especially after vacuuming
wet vegetable particles or fluids, to prevent the accumulation of
fermentation gases.
To avoid changing the classification of the work area, the
container must be emptied outside the zone (zone without
ATEX classification). Bring the vacuum cleaner out of the
ATEX classified area, then release the container and empty it.
On centralized dust extraction plants, the user must observe
procedures and use methods and accessories for emptying the
bin that prevent any alteration of the classification in the Zone
where the plant is installed. Only replace accessories supplied
by the manufacturer with original spare parts.
In the case of non-observance of the above, the Declaration of
Conformity is void.
Specific maintenance and other precautions
Always perform the service operations and checks described
in the standard instruction manual of the machine being used.
Check regularly, and in particular while emptying the dust
container, that the filters are in good condition (included the
safety metallic filter, if equipped), so as to prevent breakage,
wear, damages and/or tearing of the filter cloth, which may
result in dust dispersion and exhaust emission. This may
generate dangerous clouds. Check that the filter is intact
before using the machine as follows: vacuum fine inert dust
(e.g.: talc, chalk, scagliola...) and make sure it is not blown out
of the outlet.
GB
Periodically clean the motor cooling fan to prevent the motor
from overheating.
Use antistatic suction hoses suitable for the type of material
to vacuum. The hoses should not produce sparks or create
electrostatic charges caused by the tube rubbing.
CAtex
Only use original Nilfisk antistatic hoses and accessories.
The antistatic hoses must be grounded to prevent electrostatic
charges. Using an ohmmeter, check for the correct galvanic
connection (electrical continuity) between the hoses and the
accessories being used. This is to prevent the operator being
exposed to fire hazards and the risk of electric shocks.
All the machines that have the EXA acronym in the model
description, are equipped with an inlet that allows for coupling
only with Nilfisk EXA model accessories.
All EXA accessories are certified and do not have an
independent function, thus are classified as components.
They can be used only with Nilfisk industrial vacuum cleaners
or with other equipment from the same manufacturer, for their
intended use, already equipped with Ex marking and related
declaration of conformity, in compliance with the instruction
indicated in their use and maintenance manual and in those of
the equipment to which they are connected.
This correct coupling guarantees full compliance with the ATEX
Directive without requiring further checks and/or certifications.
If necessary, contact Nilfisk service centre only.
Do not rub non-metal parts with clothes, rags, or fabrics
of any kinds (cotton, wool, synthetic, paper, etc.) that
can generate dangerous electrostatic charges.
For cleaning non metal parts, use wet clothes or rags in
order to reduce the electrostatic charges.
In any case, cleaning procedures must be performed
outside the area that has been classified as dangerous
for risk of explosion.
