ATTENTION!
The use of sulphuric acid is generally possible up to a concentration of 50%. When
using other acids (e.g., hydrochloric acid, dissolved sodium bisulphate, etc.), the
changed dosing performance and/or increased corrosiveness must be observed! We
recommend consultation with the company WDT!
NOTICE!
When refilling the pool, the pH value must be manually brought to the desired value,
since a relatively large amount of acid is required to reach the desired value with a high
pH value and extreme hardness. This would take too long using only the GRANUDOS’s
acid pump, with a correspondingly poor disinfection power at high pH values, or it
would lead to a fault indication due to the target value not being reached.

Shock chlorination
With this menu, you can adjust the dosing performance for chlorine and pH for a shock
chlorination. Please select a dosing performance that ensures the availability of the
desired concentration during the shock chlorination.
This dosing performance is used when a filter disinfection is requested by the CCT.
For monitoring purposes, the chlorine concentration
should be checked several times
during shock chlorination.
