Measuring Concentration
The concentration of free available chlorine (FAC) can be measured with standard chlorine test paper. The range and
sensitivity measurable are 10, 50, 100, and 200 ppm.
For greater accuracy or to measure high range free available chlorine levels, the chlorine concentration can be measured
with a high range chlorine photometer.

Maintenance
Over time and depending on use, mineral scale can build-up on the electrolysis cells. Mineral scale build-up depends on
the quality of the inflow water. If the hardness of the inflow water is less than 80 ppm, scale will build up very slowly and
the system may not require maintenance for many years. Using the incorrect salt can cause mineral scale to build up very
quickly. If mineral scale does build up, the electrical current required to generate a free chlorine solution of hypochlorous
acid will be disrupted.
When to do Maintenance:
When the actual ampere of the system drops to a level below 90% of the set ampere, the systems electrolysis cells should
be descaled of mineral deposits.
How to do Maintenance:
Simply run the system using additive formula #3 with hydrochloric acid (HCl). The HCl will descale the mineral deposits
from the electrolysis cells. Run the system until the actual ampere returns to the set ampere. This could take 30 minutes or
several hours depending on the amount of scale.
