5. Slowly open the sampling tap and allow the air to bleed out.
Once pure water flows from the tap, leave it running for 1
min. Then take a sample: Check the hardness of the soft‐
ened water (order no. Z90.2093, van den Heuvel Watertech‐
nologie b.v.). The hardness must be < 0,1°dH.
Measuring the hardness of the softened water:
It is essential to avoid all perspiration traces and dust in
n
this process!
Flush the measuring tube and its lid with sampling water.
Fill the measuring tube with the water sample up to the
n
10 ml mark.
Add 1 drop of indicator.
n
Close the measuring tube and turn it repeatedly upside
n
down - do not shake it.
If the sample turns GREEN, the water has the correct
n
hardness (< 0.05 °dH). The water is suitable for further
use.
If the sample turns RED, the water hardness is > 0.05
°dH.
Add another 1 drop of indicator.
If the sample turns RED, contact customer service.
If the sample turns GREEN, take another sample on the
next day and repeat the measurement.
If the sample turns GREEN, the water has the correct
hardness (0.1 ... 0.05 °dH). The water is suitable for fur‐
ther use.
If the sample turns RED, contact customer service.
6. Switch on the main switch or the emergency stop switch.
7. Check the water feed for sufficient pressure (approx. 2 bar
downstream of the non-return valve).
If the pressure exceeds 6 bar, it is essential to install a pres‐
sure reducer.
8. Check that the brine storage tank is filled with softened
water.
9. Check that the feed to the brine storage tank is stopped by
the level switch.
10. Bleed the brine metering pump (bubbles in the hose?) and
check if it pumps up to its setpoint.
11. Optional: Check the modem or internet connection, if avail‐
able.
'SERVICE' menu, under 'Fill cell manually' press the
12. In the
[On] button.
13. [START / STOP] to start production.
Use
14. Check the system's function.
In case of alarms - see the "Faults - Errors" chapter
15. Check the product's chlorine content by means of a thiosul‐
fate titration (chemical order no. 17110946, van den Heuvel
Watertechnologie b.v.).
The measuring range is 10 ... 200 mg/l. Therefore dilute the
water sample with distilled water at a ratio of 1:100.
16. For 1 week, check daily whether the water hardness is < 0.1
°dH.
