Identification of components
Refer to Figures from 1 to 5 at the beginning of the manual.
Motor pump identification plate
Warning
Should the identification plate deteriorate during use, contact the Manufacturer or a Skilled Techni-
cian to have it restored.
The identification plate (4) shows the motor pump model, the serial number, the year of manufacture and the
main electrical and mechanical specifications (max. flow rate, max. pressure, power supply voltage, input, etc.).
It is located on the motor pump casing.
Safety device
a) Pressure switch.
This device, suitably calibrated by the Manufacturer, limits the maximum operating pressure, preventing haz-
ardous pressure levels, when the delivery is closed or when trying to set pressure values above the maximum
permitted ones.
Warning
The pressure switch is calibrated by the motor pump Manufacturer. Do not attempt to alter the settings.
b) Protection fuse.
This device stops the motor pump from working in case of excessive absorption.
If one of these trips, proceed as follows, keeping to the indications shown in the manual of the machine
in which the motor pump is integrated:
• stop the machine and disconnect the power supply;
• release any residual pressure in the high-pressure circuit;
• replace the fuse with another suitable one (refer also to the paragraph "Specifi cations and technical data";
• make sure the instructions have been followed in the paragraph "Checking and connecting up to the power
supply";
• connect the power supply again and repeat the start procedure.
Warning
In case these safety devices trip frequently, do not use the motor pump (and therefore the machine in
which it is integrated) without first having it checked by a Skilled Technician.
