Jura Capresso IMPRESSA X70 manual Adjusting for water hardness, Use of Claris filter cartridges

6. Adjusting for water hardness

The water is heated inside the machine. With use, this leads to calcium deposits (furring) forming on the machine. This will be automatically indicated on the display.

For this reason, it is necessary to adjust the machine to the hardness of your local water before you use it for the first time. Use the enclosed test-sticks for this purpose.

1° water hardness on the German scale represents 1.79° on the French scale.

The machine has got 5 hardness settings to choose from. While adjusting the chosen grade is shown on the display.

The symbols on the display mean:

HARDNESS
LEVEL – –	water hardness function is switched off
HARDNESS	German water hardness	1 – 7°
LEVEL 1	French water hardness	1.79 – 12.53°
HARDNESS	German water hardness	8 – 15°
LEVEL 2	French water hardness	14.32 – 26.85°
HARDNESS	German water hardness	16 – 23°
LEVEL 3	French water hardness	28.64 – 41.14°
HARDNESS	German water hardness	24 – 30°
LEVEL 4	French water hardness	42.96 – 53.7°
