Check permanent hardness mains
water
Hardness control is carried out by means of test kits.
If the mains water total hardness changes, calculate and
adjust the soft water quantity again according to
appendices 2 and 3.
Setting of mains water hardness is according to chapter
V
/ point 4.
Check soft water hardness
The soft water total hardness is:
- in case of reduced brining rate > 17,9 ppm CaCO
3
- in case of softeners with blending, the total
hardness is normally adjusted to ca. 60 ppm for
domestic application.
Setting is done at the blending unit of the assembly
mount or an external blending.
Check settings of control
Interval:
after 2 months

V

Check salt level in brine tank
Re-fill:
After visual inspection!
In order to guarantee regeneration of the system, the
brine tank must always be filled with sufficient regenerant
(as per DIN 19604) in the form of salt tablets.
The regeneration salt should be of high purity in order to
avoid foreign particles impairing the system operation due
to residues and deposits.
For hygiene reasons the below shall be considered:
- Salt tablets shall be cleaned prior to use so that no
contamination can penetrate the brine tank
- The regeneration salt shall be filled direct from the
open package into the brine tank
- It must be guaranteed that the brine tank is not
overfilled with salt
- A free space to rim of 100 to 200 mm at least shall
be maintained (dependent on size of brine tank)
- The brine tank must be closed again carefully
afterwards
- Once opened packages shall not be used
- The regeneration salt shall be stored in clean
and dry areas
