rinsing

The softener displays the message: reGe?
Press the oK key (once or 3 times, depending on your model). reGe 1 is displayed and a complete
regeneration starts.
Progressively open the bypass tap => water flows from the hydraulic block to the drain through
the evacuation tube. Let it flow in order to fully rinse the softener.
Stop this rinsing by pressing oK during 5 seconds. Then serV is displayed on the screen.

residual hardness setting

The hardness is measured in degrees (French °f or German °dH degrees)
1°f = 10 milligrams of "lime scale" in one liter of water
1°dH = 1.78 °f
The hardness measurement is done with a kit of reactive stripes or colored reactive liquid. See further,
in the chapter Routine maintenance.
It is possible to blend the softened water produced by the device with raw water, using a blending unit
located on the rear side of the hydraulic block, in order to reach a residual hardness of few degrees
(value depending on the country habits).
First, turn counterclockwise the knob (26) at its maximum. Then screw
the knob (27) until it reaches its lowest level. Thus the outlet water is
fully softened (hardness =0°)
Then turn clockwise the knob (26) of half a turn. The outlet water is
then slightly blended with raw water.
Slightly open any tap downstream from the softener (or use the sam-
pling tap of the bypass) and measure the water hardness at this point.
Use the knob (26) to tune the hardness for low consumption flow rates:
- Clockwise to increase it
- Counterclockwise to reduce it
For hardness tuning at high flow rates, largely open a tap downstream of the softener and measure
again the hardness.
Use this time the knob (27) to tune the hardness:
- Unscrew to increase it
- Screw to decrease it
NoTe: it is under the user's responsibility to define the residual hardness compatible with the
equipment installed downstream of the softener.
