Determining The Water Hardness - Jura ENA Micro 9 One Touch Instructions For Use Manual

Determining the water hardness

The harder the water is, the more frequently the
ENA needs to be descaled. It is therefore important
to adjust the water hardness.
The water hardness can be adjusted on a continu-
ous scale between 1° dH and 30° dH.
