Application and Dosage
One aerosol (265ml) will protect a 100 litre system or up to ten single radiators and is added via a radiator or filling loop. Fernox Boiler Noise Silencer F2 Express can be dispensed directly into a radiator air vent or system filling loop using the appropriate special adapter supplied with the product. The whole process takes less than two minutes. Too much treatment will not cause problems and is preferable to insufficient dosing. Severe noise may require more than one application. For long term protection against the effects of corrosion and limescale we recommend systems are cleaned using Fernox Cleaner F5 Express and inhibited with a Fernox Protector F1 Express. In single feed indirect cylinders, e.g. 'Primatic' or similar, potable water chemicals must be used.
