IV 1.4.4. Preparation of the chemical solution
Wear protection clothes!
When preparing the solution, 9 l pure water and the chlorine media (corresponding
to the concentration) in the following mentioned quantities have to be stirred well.
Chlorine bleaching solution 12 % 450 g
Chloramin 28 % 190 g
HTH-chlorine 60 % 90 g
After removal of the screwing, the prepared solution is filled (funnel) into the
chlorine solution bag. The tank deaerator must be opened.
Before refilling the empty dosator, the motive water has to be discharged through
the tank drain.
Before coupling the dosator into the pure water, the filter plant is switched again to
circuit.
IV 1.4.5 Commissioning
During commissioning of the dosator, the following points have to be carried out
exacty:
1. Close chlorine solution gate valve or separate quick-coupling
respectively
2. Close tank drain
3. Open adjusting valve completely
4. Open tank de-aeration until motive water flows out
5. Close tank de-aerator
6. Open chlorine solution gate valve or connect quick-coupling respectively and
wait until chlorine solution flows from the chlorine solution bag through the
transparent overflow pipe
7. Adjust control valve to demanded value
