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.

Degree (°dH)
Not active –

Soft water > 4
Hard water > 8.4

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 running water.
T 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 discoloration of the
Aquadur® test strip and the description on
the packaging.
The water hardness can now be adjusted.
