Application and Dosage
For optimum results, the entire system should be completely drainable. HVAC Cleaner F3 should be dosed at a concentration of 0.5%. Add via the feed and expansion tank or inject directly into the system via a suitable point (e.g. dosing pot). For pre-commission cleaning, circulate HVAC Cleaner F3 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 HVAC Cleaner F3 may be necessary if systems are heavily sludged. Drain and flush with cold water until the water is clear and the HVAC Cleaner F3 has been rinsed from the system. HVAC Cleaner F3 will usually be removed after 3 complete flushes. Finally add the appropriate Fernox inhibitor such as HVAC Protector F1 to prevent further corrosion damage and scale deposits.
