Check pressure switch; replace it, if required.
Wait for regeneration to end.
Check the base exchanger.
Check filter; replace the filter inlay, if required
Add salt, add water and wait for brine formation (ap-
prox. 2 hours); start regeneration, check the base ex-
changer, if required.
Check mains water supply; open the inlet valve fully,
if required.
Check filter; replace the filter inlay, if required
Measure the temperature of the softened water and
compare it with the technical data.
Reset the operating pressure.
Decalcify the membrane; replace it, if necessary
Check level switch.
Rinse the membrane thoroughly for a long time; re-
place it if necessary. In future remember: Water is of
potable quality; avoid long idling periods.
Check conductivity of softened water.
Replace washer or membrane. Check conductivity
