Information about the Cromargan® vacuum jug
(only version with vacuum jug)
The jug is designed as a serving jug and best keeps the content warm when it is full.
When filled partially and for residual amounts, the keep-warm time can be reduced
substantially. It is best if the jug is rinsed with hot water prior to preparing the
coffee.
The seal made by the drip-through lid is not 100% sealed due to technical reasons so
that it is still easy to open, even after the coffee has cooled down. To close, simply
slightly tighten the lid. The filled jug can only be used upright.
To pour, press the pouring button on the handle.
To open the jug, turn the lid slightly counter-clockwise. After closing the lid, ensure
that the pouring button is again over the handle of the jug.
The double-walled Cromargan® jug is absolutely break-proof. Nevertheless, it should
be protected against mechanical stresses.
Rinse the jug regularly. If iron particles from water accumulate on the Cromargan®
surface, they can create pitting at those points. Therefore, remove these deposits
immediately with a stainless steel cleaning agent.

Cleaning and care

Cleaning
Disconnect the mains plug and allow the appliance to cool down.
Do not immerse the device in water, but rather only wipe the outside with a damp
cloth to which some washing-up liquid has been added.
Do not use any harsh and abrasive cleaning agents.
The filter (2), glass jug (7) and vacuum jug (7) are cleaned under running water.
Calcification
Calcium deposits lead to a longer brewing time and a lower quality of your coffee.
In addition, calcium deposits lead to energy losses and affect the service life of the
device.
It switches off prematurely if the limescale layer is too thick. It is then only possible
to remove with great difficulty. You should therefore descale regularly, at the latest
however in the event of significantly longer brewing times or increased noise.
