2 Preparing and using your IMPRESSA for the first time
The water hardness can be adjusted between 1° dH and
30° dH. This can also be deactivated, which means that the
IMPRESSA won’t let you know when it has to be descaled.
You can find out what the water hardness is by using the Aquadur®
test strips enclosed in the Welcome Pack.
Hold the test strip briefly (for one second) under flowing
mains water. Shake off the water.
Wait for about 1 minute.
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.
Example: To change the water hardness from
16° dH
to
25° dH
