Explanation: It is vital that you check the pressures specified above when commissioning the pump. In fact, a pressure
below these minimum values leads to the premature wearing of the pump assembly.
Setting: Close the delivery valve progressively in order to achieve the minimum pressure that corresponds to your model.

Check the condition of the couplings and seals along the suction pipe
Invert 2 phases on the electricity supply
Check the condition of the couplings and seals along the suction pipe
Invert 2 phases on the electricity supply
Avoid: long pipes, numerous elbows, positioning the pump higher than
the water level, narrow pipes
Make sure the voltage in your supply corresponds to the value
specified on the motor data plate
Make sure the fan grid is free of obstacles (at least 30 cm clearance
between the wall and the fan)
Increase the pump's operating pressure by slightly closing the delivery
valve (see table below)
