Application and Dosage
The recommended ‘in use’ concentration of the product is 0.265%. One 265ml bottle will treat an average domestic system (100 litres). For open vented systems add via the feed and expansion tank. For sealed systems add via a suitable dosing point (e.g. a towel rail or an in-line system filter). Alternatively, use a suitable dosing vessel to inject the product into the system.
In single feed indirect cylinders, e.g. “Primatic” or similar, potable water chemicals must be used.
We recommend untreated or sludged systems are thoroughly cleaned and flushed in accordance with
BS 7593:2019 and Benchmark using Fernox Cleaner F3/ F8, before treating with Fernox Protector F1, as existing debris can damage the installation.
