Y Do not exceed the design limits given on the dataplate.
! Y It is the user’s responsibility to avoid loads different
from the internal static pressure. The unit must be appropriately
protected whenever risks of seismic phenomena exist.
Only use the unit for professional work and for its intended
purpose.
The user is responsible for analysing the application aspects for
product installation, and following all the applicable industrial
and safety standards and regulations contained in the product
instruction manual or other documentation supplied with the
unit.
Tampering or replacement of any parts by unauthorised per-
sonnel and/or improper machine use exonerate the manufac-
turer from all responsibility and invalidate the warranty.
The manufacturer declines and present or future liability for
damage to persons, things and the machine, due to negligence
of the operators, non-compliance with all the instructions given
in this manual, and non-application of current regulations re-
garding safety of the system.
The manufacturer declines any liability for damage due to
alterations and/or changes to the packing.
It is the responsibility of the user to ensure that the speci ca-

or options are fully comprehensive for the correct or foresee-
able use of the machine itself or its components.
IMPORTANT: The manufacturer reserves the right to modify
this manual at any time.
For the most comprehensive and updated information, the
user is advised to consult the manual supplied with the
unit.
1.4 Residual risks
The installation, start up, stopping and maintenance of the
machine must be performed in accordance with the information
and instructions given in the technical documentation supplied
and always in such a way to avoid the creation of a hazardous
situation.
