Preparing the brine
All commercially available regenerative salts conforming to EN 973 can be
used (in loose or tablet form).

nerative to a filling height of 250–350 mm (see Technical specifications). The
brine cavity automatically fills with water during the “disinfection” stage. Wait
and then check that the automatic water refilling turns off as soon as the
water has risen above the sieve base. Pour in the regenerative (always
adding whole units) up to a maximum of 75–150 kg. Close the cover and lock
it.

water equals approximately 8 °d. Fine adjust the hardness of the blended
water using the small spindle (black turning knob). The small spindle should
never be opened completely, since only untreated water could be drawn via
this opening in the case of limited water use. (Only use an AQUATEST
hardness tester to set, check and correct hardness.)

The sodium content increases by 8.2 mg/l if the hardness of untreated water
is decreased by 1 °d.
Hardness of untreated water – hardness of blended water x 8.2 mg/l =
increase in the sodium content.
Ask at the water works what the sodium content of untreated water is (e.g.
10 mg/l).
Sodium content of untreated water + increase of sodium content (due to
softening) = sodium content of partially softened water.
Repeated dosage further increases the sodium content by approx. 5 mg/l.
Drinking water regulations stipulate a sodium limit of 200 mg/l. We recommend
setting the treated water to a hardness between 4 °d and 8 °d. If the mandatory
sodium limit of 200 mg/l is exceeded, the blended water hardness may have
to be set at more than 8 °d.
The unit is now ready for use.

If there is a delay between the installation of the unit and handover to the
user, a manual regeneration must be performed. The operator must be told
how the unit works as well as how to operate and inspect it. Ensure that the
operator receives the installation and operating manual.
