Application and Dosage
One 500 ml pack is usually sufficient to treat a typical central heating system. Too much treatment will not cause problems and is preferable to insufficient dosing.  Severe noise may require more than one application.

For open vented systems add via the head tank. For sealed systems add via the radiator using a Fernox Injector.

For long term protection against corrosion and limescale we recommend systems are cleansed using an appropriate Fernox Cleaner F3 and then protected with a Fernox Protector F1.

In single feed indirect cylinders, e.g. 'Primatic' or similar, potable water chemicals must be used.
