You will then be able to read the degree of water hardness
from the discolouration of the Aquadur® test strip and the
description on the packaging.
When using the machine for the first time, you can choose whether
you want to operate JURA
with
or
without
the CLARIS Smart filter
cartridge. If the water hardness is 10 °dH or more (total hardness),
we recommend using the filter cartridge.
If the machine is operated with a defective mains cable, there is a
danger of potentially fatal electric shock.
