The unit is preset to 4°d.
To test the water hardness, allow the nearest cold
water tap to run for a while (approx. 500-600 l/h)
and check the hardness of the blended water us-
ing the AQUATEST hardness tester. Adjust with
the blending valve V V V V V until the desired value (BWT
recommendation 4 - 8°d) is reached.

If there is a delay between the installation/start-up
of the unit and transfer to the operator, a manual
regeneration must be performed.
The operator must be told how the unit works as
well as how to operate and inspect it. Ensure that
the operator receives the installation and operat-
ing manual.
