a1) Check that the pump body, pos. 14.00 is filled with water by opening the filler cap pos.14.04 and top up with water
until it is completely filled.
a2) If the water level inside the pump body, pos. 14.00, completely filled should continue to fall, check the tightness of
the complete valve pos. 14.64 by removing the suction pipe from the pump body, pos. 14.00 and check that the shutter
of the valve itself closes the water passage correctly. If necessary, remove any foreign bodies between the valve body
and the shutter.
If the problem persists, contact an authorised service centre

- Read the voltage on the display and check the line voltage. If the two values are consistent and below the 185V
threshold, adjust the power supply line, using a cable with a larger section and/or provide a shorter line.
- Contact the operator to check the quality of the power supply being used
- If the problem persists, contact an authorised service centre
- Read the voltage on the display and check the line voltage.
- Contact the operator to check the quality of the power supply being used
a1) Check the correct setting of the parameters according to the type of system (in intake or positive suction head). If
necessary, reset the previously set settings (follow the programming guide instructions, para. 7).
a2) Follow the procedure for First Power On
b1) Check that, once the shut-off valve on the delivery side is closed, the electric pump does not start cycling again. If
the electric pump does not restart, this means that there are pressure drops in the system delivery.
b2) Once the shut-off valve on the delivery side has been closed, if the electric pump continues to cycle, the non-return
valve pos. 14.64 may not close the water passage properly. If necessary, remove any foreign bodies between the valve
body and the shutter.
If the problem persists, contact an authorised service centre
Try to unlock the shaft with a flat screwdriver using the dedicated notch on the shaft visible in the rear part of the electric
pump through the cap pos. 90.00
If the problem persists, contact an authorised service centre
Open the filler cap pos.14.04 and check complete filling of the pump body pos. 14.00, top up if necessary and check the
seal of the non-return valve pos. 14.64 making sure that the water level in the pump body remains constant.
a) Pump not suitable for the application
b) Increase the diameter of the suction pipe
c) Check the correct positioning and length of the suction pipe
d) Check that there are no air intakes by tightening the joints and check that the pipe is intact
e) Disassemble the suction pipe and check the correct movement of the shutter of the non-return valve, pos. 14.64
f) Check that the suction pipe is not clogged and that the section of the pipe is not less than 1"
g) Pipe too long and/or diameter too large
h) Restore and guarantee the correct suction water level. Install an electric float in the suction tank which interrupts the
operation of the pump below the safety level (0.5m above the axis of the suction pipe)
a) Pump not suitable for the application
b) Prepare a guard from radiation around the electric pump
c) Check the spaces around the electric pump, check that the fan rotates integrally with the shaft (for Mèta)
d) If the problem persists, contact an authorised service centre
a) The maximum inlet pressure is greater than the maximum value AP01, insert a pressure reducer on the inlet
b) Avoid abrupt closing manoeuvres (e.g. avoid quick-closing solenoid valves on delivery). Fit a non-return valve on
the delivery side
c) Check the correct seal of the delivery check valve (if not present, install one)
Contact an authorised service centre
a) Install an electric float in the suction tank that stops the pump from working below the safety level (0.5m above the
axis of the suction pipe)
b) Avoid return flows with rain falls or recirculations that could disturb the incoming flow
Set the correct value of AP01 and set AP05=1
