E However, if you are using the CLARIS plus filter cartridge and
have activated it, you will not be able to adjust the water hard-
ness.
The harder the water is, the more frequently the IMPRESSA needs to
be descaled. It is therefore important to adjust the water hardness.
The water hardness can be adjusted on a continuous scale between
1° dH and 30° dH. This can also be deactivated, which means that
the IMPRESSA will not let you know when it has to be descaled.
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 one second) under flowing
water. Shake off the water.
T Wait for about one minute.
T 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.
You can now adjust the water hardness.
