GENERAL
Read this documentation carefully before installation. It contains fundamental instructions to help
you get to know the pump so that you can make the best use of its various possibilities of
application. Observing these indications will ensure long life of the pump parts and avoid risks. The
manual must always be kept within reach in the place where the machine is to be used.
Installation and functioning must comply with the safety regulations in force in the country in which the
Product is installed. The entire operation must be carried out in a workmanlike manner, exclusively by
skilled personnel (paragraph 6.1), in possession of the technical qualifications indicated by the standards
in force. Failure to comply with the safety regulations not only causes risk to personal safety and damage
to the equipment, but invalidates every right to assistance under guarantee. The pump may be installed
in either horizontal or vertical position, as long as the motor is always above the pump.
