Other parts of the plant
To avoid altering the ATEX classification of the plant, parts
should only be replaced with original Nilfisk spare parts. Make
sure that the hoses are antistatic.
Proper and Improper Use:
The metallic parts of the plants (silos, hoppers, hoses and pipes)
may be made of and supplied in various materials (galvanized
steel, stainless steel, plastic, rubber, etc.). The type, nature
and materials of construction are determined on the basis of
the materials to vacuum and/or transport, as declared by the
Customer in the order.
These elements are taken into consideration by Nilfisk in the
ATEX risk assessment phase for the specific plant:
1. Nilfisk is therefore not responsible for any risks, danger or
damage caused by any other use of the plant not described
and indicated in the Nilfisk Order Confirmation.
2. Furthermore, Nilfisk is not responsible for the consequences
of any other substances or materials being vacuumed and/
or transported, which are not indicated in the Nilfisk Order
Confirmation.

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.
