TRANSLATION OF THE ORIGINAL INSTRUCTIONS
This manual is divided into two separate parts.
The fi rst part is for use by both the end user and the Skilled Technician; the second part is only for
use by the Skilled Technician.
This manual is completed by another, specific for each series of pumps, which contains exploded views,
overall dimensions, technical data, detailed specifications, etc...
By Skilled Technician is meant:
• the Manufacturer of the machine (e.g. motor driven pump) in which the pump is integrated (from
now on, when reference is made to "machine in which the pump is integrated", this may also refer
to "system in which the pump is integrated", such as, for example, in the case of a pumping station);
• a person, generally from the service centre, who has received appropriate training and is authorised
to carry out special maintenance and repairs on the pump and on the machine which incorporates
the pump. Any work on its electrical parts must be carried out by a Skilled Technician who is also
a Qualified Electrician, i.e. a person with professional training who is authorised to check, install
and repair electrical equipment correctly and according to current regulations in the country where
the pump is installed.
Carefully read the pump manuals and that of the machine in which the pump is integrated: carefully
comply with the instructions contained in them.
Special care must be given to reading the parts of the text marked by the symbol:
inasmuch as these contain important safety instructions concerning pump operation.
The Manufacturer disclaims all liability relating to damage caused by:
• failure to abide by the contents of the pump manuals and the manual of the machine in which the
pump is integrated;
• the pump being used in ways other than those indicated in the "INTENDED USE" paragraph;
• the pump being used in ways contrary to applicable laws on safety and prevention of work accidents;
• tampering with the safety and max operating pressure limitation devices;
• incorrect assembly and installation;
• incorrect maintenance;
• changes made or jobs done on the pump without the permission of the Manufacturer;
• use of non-original spare parts or which are not suitable for the pump model;
• repairs not performed by a Skilled Technician.
