Page 31: Sbs Valve
Valve SBS To ensure correct operation of the valve SBS a long espresso coffee should be made, and during preparation of the latter, check the difference in speed of delivery between the maximum and minimum positions. The difference in delivery speed is approx. 2.5 times greater (and therefore VERY obvious!!). An excessively fine grinding influences operation of the valve SBS.
Page 32: Aqua Prima Filter
This guarantees constant optimal water for a perfect coffee. In four phases Saeco water first purifies the water, to achieve a unique coffee. The active carbons eliminate unpleasant odours or substances from the water, such as chlorine. The silver coating of the active carbon obstructs the reproduction of germs.
