8. Check that there is adequate salt (EN973) in the brine tank.
Check that the water supply is running correctly.
Check that the brine tank is filled with softened water. The
brine tank should automatically fill with softened water once
you have switched on the fuses and connected the level
switch in the control cabinet.
9. Check that the feed to the brine tank is stopped by the level
switch.
10. INFORMATION: The water hardness is measured in °dH.
The water softener is factory-set to a regeneration time of 2
days. This regeneration time is based on 24-hour production
and a maximum supply water hardness of 15 °dH. If the
hardness level is 15 °dH, you can leave the water softener
time setting unchanged. If the hardness of the supply water
measured is between 10 °dH ... 15 °dH, set the regeneration
time to 3 days. If the hardness of the supply water measured
is between 0 °dH ... 10 °dH, set the regeneration time to 4
days.
Water hardness test
Follow the instructions for the water hardness
test in the test kit manual provided or in the
manual for the measuring instrument you are
using.
Set the regeneration time of the softener in line with the hard‐
ness of the supply water measured. Now set the regenera‐
tion time in accordance with the parameter list below.

11. Use the water hardness measuring test kit to measure the
hardness of the softened water. Use the test kit and use the
[LOW RANGE] test process to measure the feed water.
The regeneration time is around 70 minutes. Measure the
hardness of the water again after this regeneration time.
