Assembly of pipes
• The pipes should be assembled before and after the pump and should have diame-
ters equal of above those of the pump inlet.
• The suction and expulsion pipes should never stay connected to the pump.
• Well seal all the connections and the cover of the pump to avoid possible water
leaks into the motor, which could damage it.
Tests before starting the pump
Carry out the following operations before starting the pump:
• Check that the power supply as well its frequency correspond to the information of
pump specification plate.
• Before starting the pump, fill it with water for self-priming of the pump.
• Check that the mains voltage and frequency correspond with those indicated on the
pump characteristics plate
• The pump can continuously work.
Starting the pump
Start the pump only when the suction and expulsion tubes are connected to the inlet
and outlet of the pump. Check there are no obstacles in the pipes.
Maintenance and cleaning
• Your new pump does not need any specific or programmed maintenance In the
case that the pump is not used during some time, we recommend dismantling it and
cleaning it to be kept in a dry and well-aired place.
• If the electrical cable is damaged, the manufacturer, its agent, or any other qualified
person to avoid any danger should replace it to avoid any dangers.
• Regularly clean your pump, removing any dirt from the filer so the inlet pipe is not
blocked or the pump damaged.
• Pump components that, due to their normal use, suffer wear and/or tear must be
regularly replaced to ensure good pump performance.
• For regular control:
•Check that the mechanical parts are tightly secured and check the condition of the
screws supporting the machine.
•Check that the power conductors and isolating parts are in their correct position, are
secure and in a good state of repair.
Check the temperature of the machine and the electric motor. In the event of a fault,
stop the machine immediately and contact the nearest Technical Assistance Service.
• Check for machine vibrations. In the event of a fault, stop the machine immediately
and contact the nearest Technical Assistance.
