2.6 Filling the water tank
Caution!
Possible damage to your automatic coffee machine due to unsuitable liquids!
Liquids other than drinking water can damage your coffee machine or can result in clogging.
>Fill the water tank of your automatic coffee machine only with clean, cold drinking water.
>Never fill the water tank with hot water, mineral water or milk.

Initial setup
13
>Press the milk tube into the guide. See to it that the milk tube does not lie in front of the grounds
container.
2.8 Filling the coffee bean hopper
Once unpacked, roasted coffee loses its aroma in few days.
Therefore, pour only as many coffee beans in the coffee bean hopper as you expect to use in the next
few days. So that you can enjoy the full aroma of your coffee, it is better to frequently refill with beans.
Each automatic coffee machine is checked thoroughly before shipment. Therefore, coffee grounds
residue may remain in the grinder. Your coffee machine will definitely not be a used one.
Hazard!
Possible injuries due to the grinders!
As long as your automatic coffee machine is switched on and connected to the power supply, the grinder
of your automatic coffee machine can start up and you may suffer injury.
>Do not reach into the coffee bean hopper of your coffee machine when the coffee machine is not
switched off and removed from the mains.
Caution!
Possible damage to your automatic coffee machine due to foreign bodies!
Foreign bodies that are present in the coffee bean hopper can damage the grinders.
>Make sure that no foreign bodies (e.g. metal parts) are present in the coffee bean hopper.
>Pour only appropriate coffee beans into the coffee bean hopper.
