SETTING THE HARDNESS
SETTING FOR HWE
Set the desired mixed water hardness on the
blending valve.
Turn in the „SOFT" direction = soft water
Turn in the „HARD" direction = harder water
SETTING FOR HVE
Deactivate the blending valve:
Use a hexagon socket wrench to turn the spindle
completely clockwise.
Hold the outer ring (with the embossed
with the embossed indicator arrow).
Determine the output quality with a conductivity meter:
Remove treated water from the drain valve and measure or check the conductivity (< 100 µs). The
specifications according to VDI 2035/I must be observed.
IMPORTANT: When the blending valve is closed, raw water is no longer added!
The system can now be filled after a check.
