Cleaning with Fernox F3 on a residential heating system |
Fernox Catalogue USA |
For optimum results, the entire system should be completely drainable. Cleaner F3 2.6G should be dosed at a concentration of 0.5%. The product can be introduced into the system via a suitable point such as a dosing pot. For pre-commission cleaning, circulate Cleaner F3 2.6G for at least one hour at normal operating temperature. To remove sludge from existing systems, circulate under normal operating conditions, for up to 7 days until acceptable flow around the system has been achieved. Additional/ repeat applications of Cleaner F3 2.6G may be necessary if systems are heavily sludged. Drain and flush with cold water until the water is clear and the Cleaner F3 2.6G has been rinsed from the system. Finally, add an appropriate Fernox inhibitor such as Protector F1 2.6G to prevent further corrosion damage and scale deposits.
