MAINTENANCE AND CLEANING

It is absolutely essential to prevent any risk of the pump freezing. In the event of freezing temperatures,

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.

performed by the manufacturer or his authorized customer support service, or by an equally-qualified
