  • Page 30: Aquaclean Water Filter

    PICO BARISTO 04 OPERATING LOGIC 4.9. AquaClean water filter The SAECO AquaClean water filter purifies the water your machines uses for brewing coffee. This results in a greater coffee taste. Moreover it prevents mineral deposits in the water to build up, which eliminates the need of descaling your machine for 500000ml of water. We recommend installing the water filter AquaClean the first use of the machine to the maximum before using 5000 ml of water. After a period of uses the machine, the display will indicate when the filter needs to be replaced, the maximum limit equivalent to 62500ml. In this way you can replace the filter 8 times without the need for descaling. This equals approx. 500000ml of water. When Aquaclean filter is activated the display will show an icon indicating the percentage of use (initially 100%) . The filter should be replaced after a maximum of 62500ml of water or after 3 months of use (ma- ximum time of law) The filter can not be deactivated manually, as it must end its life cycle.
