If the pump has been used with substances that tend to form a deposit, or with water containing chlorine, rinse it after use
with a powerful jet of water in order to avoid the formation of deposits or encrustations which would reduce the
characteristics of the pump.
10. MAINTENANCE AND CLEANING
In normal operation the pump does not require any type of maintenance. In any case, all repair and maintenance work
must be carried out only after having disconnected the pump from the supply mains. When restarting the pump, ensure
that the suction filter is always fitted so as not to create the risk or possibility of accidental contact with moving parts.

Push the switch lever and disassemble the cover of the float.
Remove the float, check if the material prevents the free flow and just in case proceed to cleaning.
Assemble the parts, proceeding in inverse order to disassembly.
11. TROUBLESHOOTING
Before taking any troubleshooting action, disconnect the pump from the power supply (i.e. remove the
plug from the socket). If there is any damage to the power cable or pump, any necessary repairs or
replacements must be performed by the manufacturer or his authorized customer support service, or by
an equally-qualified party, in order to prevent all risks.
