Application and Dosage
The recommended ‘in use’ concentration of the product is 0.5%. One 500ml bottle will treat an average 3 to 4 bedroom house (100 litres). For open vented systems add via the feed and expansion tank. For sealed systems add via the radiator using a Fernox Injector. In single feed indirect cylinders, e.g. “Primatic” or similar, potable water chemicals must be used. For continued protection Fernox Protector F1 levels should be checked regularly (annually). We recommend untreated or sludged systems are thoroughly cleansed and flushed in accordance with BS7593 and Benchmark using Fernox Cleaner F3/F5, before treating with Fernox Protector F1, as existing debris can damage the installation.
