4.1 Filling with tap water

The Water display lights up. The quality of the tap water largely deter- mines the avour of the coee. Fill the water tank only with fresh, cold tap water that has not been carbonated. Change the tap water on a daily basis. Please observe the maximum lling level.

4.2 Filling with coee beans

The Coee beans display ashes. Important! Do not use freeze-dried or caramelised coee beans as they can clog the grinder. Coee powder and instant products can also damage the grinder. Roasted coee beans lose their aroma after a few days. Therefore, do not ll too many coee beans into the bean container. Caution! When you switch bean variety, a small amount of the other coee beans will remain in the grinder. The next two coee beverages will be pre- pared still with remains of the previous variety. Persons with caeine intoler- ance should only consume the third coee beverage.

To prepare milk froth or hot milk, insert the milk hose into a conventional milk pack. In addition, you can use a milk lance or a milk container. The milk lance and milk container are not included in the delivery. Always use cold milk.

4.4 Emptying the drip tray and

coee grounds container

The Drip tray display lights up. After a set number of dispensing opera- tions, the appliance will ask you to drain the drip tray and the coee grounds con- tainer. The protruding oat also shows you when it is time to empty the drip tray.Preparing beverages

The drip tray can be pulled forwards out of the appliance. Always empty both the drip tray and also the coee grounds container. Then, make sure you push the drip tray into the appliance up to the stop. Information If you empty the drip tray while the appliance is switched o, the appliance does not register this process. Therefore, it is possible that you are asked to empty the containers even though the drip tray and the coee grounds container are not yet full. 5 Preparing beverages Observe the following instructions during preparation: The water tank should be suciently full. If the lling level is too low, the appliance will ask you to rell it. There should be sucient coee beans in the bean container. The appliance asks you to rell only if there are no more coee beans in the bean con- tainer and the grinder has ground itself empty. When you prepare a beverage with milk, you need to connect a vessel lled with milk. The appliance does not indicate a lack of milk. The vessels for the beverages should be suciently large. The beverage quantity varies according to the beverage.
