ADJUSTMENTS
HARDNESS
By tightening the adjustment screw, you will open the by-pass valve, which will allow to mix raw water with machine-proces-
sed 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.
