MAINTENANCE AND CLEANING

remove the pump from the liquid, empty it and keep it in a place where it cannot freeze.
The pump must be disconnected from the mains power supply before any cleaning operation is performed.
The pump is maintenance free.
5. 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.
