No water is allowed to drip from the flushing water hose during parallel
operation. The system is in parallel operation when two blue symbols are
displayed in information level 1 (refer to chapter 7.1).
8.3 Maintenance
Some regular work is necessary in order to ensure proper functioning of the product in the
long term. For this purpose, DIN EN 806-5 recommends a semi-annual and an annual
maintenance.
8.3.1 Six-monthly maintenance
Proceed as follows to carry out the six-monthly maintenance:
1. Visually check the system for leaks
2. Check the soft water hardness (refer to chapter 7.7).
3. Check there are sufficient salt tablets in the brine tank.
The salt tablet level in the brine tank must always be higher than the water
level.
4. Check the control valve to the drain for leaks.
5. Evaluate the salt consumption subject to the water volume consumed.
8.3.2 Annual maintenance
Carrying out annual maintenance work requires specialist knowledge. This maintenance
work is only allowed to be performed by Grünbeck's technical service/authorised service
company or by tradespersons trained by Grünbeck.
The maintenance work to be performed for the annual maintenance complete the tasks that
have to be carried out in the course of the semi-annual maintenance. The maintenance work
is divided into reading and documenting operating values, general maintenance work and
maintenance work to be carried out per exchanger. In addition to the semi-annual
maintenance, the following work needs to be done:
Operating values
6. Measure the raw water hardness.
7. Align the measured raw water hardness with the setting in the control unit.
8. Measure the soft water hardness.
9. Align the measured soft water hardness with the setting in the control unit.
10. Read off the water pressure and flow pressure.
