ADJUSTMENTS
HARDNESS
By tightening the adjustment screw, you will open the by-pass valve, which will allow to mix raw water
with machine-processed water (pict. A).
At the first turn of the screw, outgoing water hardness will increase.
By loosening the adjustment screw, the by-pass valve will close (pict. B).
The closure will reduce raw water mix and lead to lower hardness values.
In order to mix a specific outgoing value, adjust the screw and test the water.
Repeat the procedure until you reach the desired hardness value.
