BRINE REGULATOR ADJUSTMENT
Remove the regulator from the brine well placed in the salt tank.
Check dimension “X” as on diagram below. Adjust it if necessary, by
sliding the float on the regulator rod.
SALT TANK PREPARATION
Load the brine tank. Do not exceed the top of the chimney so that the brine valve is accessible. Make sure that
the floor and any supports are correctly positioned.
CAUTION : It is imperative to inspect the inside of the brine tank. In some cases, it is observed the creation
of a vault of salt which makes think that the salt loading is correct. Regularly check that the salt on the top
is not set in mass.
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 hydrau-
lic block, in order to reach a residual hardness of few degrees (value
depending on the country habits).
First, turn counterclockwise the knob ❶ at its maximum. Then screw
the knob ❷ until it reaches its lowest level. Thus, the outlet water is
fully softened (hardness =0°)
Then turn clockwise the knob ❶ 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 ❶ 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 ❷ to tune the hardness:
- Unscrew to increase it
- Screw to decrease it
NOTA : it is under the user’s responsibility to define the residual hardness compatible with the equip-
ment installed downstream of the softener.
