Instructions for use

To obtain optimal results, it is advisable to follow a precise operating procedure. First, dilute the product in water according to the indicated ratio based on the degree of incrustation. Use a circulation pump to circulate the solution in the system for the necessary time. Monitor the process using the colorimetric indicator: when the color changes from red to yellow/orange, the product is exhausted. Finally, rinse the system thoroughly with clean water until the pH is neutralized. For lasting protection, it is advisable to complete the treatment with the application of a corrosion inhibitor from the same Rothenberger range.
