Wiring diagram for connecting the unit to different kinds of pump`s motors
Read the indicated pressure showed in the pressure gauge when the pump starts and perform on the
screw according to the wished side. Pressure adjusting must be performed by professional/ As per
standards the starting pressure should be 0.2 bar higher than the manometric one, and the pump will
have to give at least a pressure 0.8 bar higher than the adjusted one.
This operation only adjusts the starting pressure, not the working pressure which only depends on the
pump feature. It will be easier to proceed with the adjustment if a tap of the installation is opened. That
will reduce the internal pressure of the control.
