Rinsing of the filter stops automatically after approximately
17 oz (500 ml). The JURA heats up and is once more ready for
use. The filter is now activated.
E If you are using the CLEARYL Blue filter cartridge and have
activated it in programming mode, you will not be able to
adjust the water hardness.
The harder the water is, the more frequently the JURA needs to be
descaled. It is therefore important to set the water hardness
accurately.
The water hardness can be adjusted on a continuous scale between
1 °dH and 30 °dH.
You can find out what the water hardness is by using the Aquadur®
test strip supplied as standard.
T Hold the test strip briefly (for 1 second) under flowing water.
