Application, Fitting & Dosing

The recommended in-use concentration of the product is 1% v / v%. Fernox FC1 Inhibitor can be introduced into the system via a suitable point (e.g. dosing pot). To ensure rapid dispersion, partly or completely drain down and introduce Fernox FC1 Inhibitor whilst refilling. We recommend untreated systems are thoroughly cleaned and flushed using Fernox FC3 Cleaner before treating with Fernox FC1 Inhibitor, as existing debris can damage the installation. For continued protection we recommend the inhibitor level is checked regularly (annually). The concentration of the product can be easily measured on site using a Fernox Protector Test Kit.

Fernox FC1 Inhibitor is classified as non-hazardous, but as with all chemicals, keep out of reach of children. Do not mix with other chemicals outside of the Fernox product range. In case of contact with eyes or skin, rinse immediately with plenty of water.
