GAGGIA BABILA 04 OPERATING LOGIC11/114.14. AquaClean water filterThe AquaClean filter is designed to reduce limescale deposits in the coffee machine and provide filtered wa-ter to preserve the aroma and flavor of each cup of coffee. By using a series of 8 AquaClean filters, there is no needto descale the machine for 5000 cups (It depends both on the type of coffee used, rinsing and cleaning programs).We recommend installing the water filter AquaClean the first use of the machine to the maximum before using 5 L of water.The machine display will indicate when the filter needs to be replaced. The maximum limit is equivalent to 110 L of water.The conditions related to the filter work environment (water, therefore, an active environment for bacteria andmicroorganisms), require the replacement with a minimum frequency (we suggest 3 months from the acti-vation to ensure the best performance). The filter starts’ working from the time is filled with water and con-tinues working even with the machine off. It cannot be deactivated manually, as it must end its life cycle.At the filter activation the display shows the icon with the percentage of use:- Initially 100% then decreasing.When the autonomy of the current filter becomes less than 8 L of water the display shows:- The icon flashing slowly. It means 10%.When the autonomy of the current filter becomes less than 2 L of water the display shows- The icon flashing quickly. It means 0%.After a maximum of 110 L of water supplied the flashing light turn off and the machineneeds to be descaled.
