1. GENERAL
Read this documentation carefully before installation. 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.
Keep this manual with care for future consultation even after the first installation.
The pump must not be allowed to operate outside the limit values for flow rate, pressure, rotation speed and temperature
indicated on the electric data plate or in this manual. The electric supply values indicated on the electric data plate must be
strictly respected.
These pumps cannot be used in swimming pools, ponds or tanks in which people or
present, or for pumping hydrocarbons (petrol, diesel fuel, fuel oils, solvents, etc.) in
accordance with the accident-prevention regulations in force.
N.B.:
the technical data plate inside the plastic envelope attached to the power cable shows the same data as the plate rivetted
onto the motor cover; it is supplied in this way so that the user can attach it to the electric power supply panel. The type of
pump and its characteristics can thus be identified without having to remove the pump from its place of installation.
