2.1 How to set the blending
hardness
The small systems with economic salting (GENO-mat duo
WE-X 50, WE-X 130, WE-X 230) are equipped with a blending
unit as standard.
This blending unit is available as additional equipment for the
GENO-mat duo WE-X 65, WE-X 150, WE-X 300 systems.
Larger systems can be fitted with a blending valve R 1¼" as
additional equipment. If both soft water with 0 °dH and blended
water are needed, this blending valve is also recommended for
small systems. Refer to the operating manual for the blending
valve in systems with this equipment.

Caution! If the water softener is installed before a reverse
osmosis system, the feed line to the reverse osmosis system is
not allowed to be configured as a blending water line.

Note: The provisions of the German Drinking Water Ordinance
are binding when softening drinking water.
Sodium content (max:) 200 mg/l Note point 3.1 with regard to the
blending hardness!
Example
Softening of drinking water
Supply water (22 °dH)
contains sodium (51.6 mg/l)
Possible addition of sodium during
softening:
200 mg/l – 51.6 mg/l = 148.4 mg/l
Sodium content
Obtain the sodium content of the supply water from your water
supply provider. The sodium content increases by approx. 8.2
mg/l when softening water by 1 °dH. The water cannot be
softened unrestrictedly if the provisions of the German Drinking
Water Ordinance are to be adhered to. The permissible blending
hardness results from the limit value for the sodium content and
the supply water hardness.
200 mg/l (limit value according to the Drinking Water
Ordinance)
– x mg/l (sodium content in the supply water)
This means that the maximum
permissible softening is: y mg/l (permissible addition of sodium during softening)
Conclusion:
Blend to at least 22 – 18 = 4 °dH!
y
8 2 ,
= Z °dH (maximum possible softening)
The supply can be softened to a maximum of Z °dH. Depending
on the sodium content of the supply water, a blending hardness
needs to be selected which is below the admissible maximum of
200 mg/l.

Result
3 – 5 °dH Very soft water – ideal for thermal equipment
– possible problems when washing off soap
6 – 8 °dH Optimum soft water
