Application, Fitting & Dosing

For detailed instructions on the cleaning of central heating systems using DS40 Descaler & Cleaner please refer to the instruction leaflet inside the box. The product can be poured as a free-flowing powder directly into a powerflushing unit. Alternatively, by pre-dissolving in warm water, the product can be applied via the F&E tank or, in a sealed system, via a suitable dosing vessel into a radiator. One box (4.41 lbs) is usually sufficient to clean a typical hydronic heating system. For large systems and heavily scaled or sludged systems, additional powder may need to be added. During the early part of the clean, a color change (red-yellow) indicates that the product is exhausted and more powder needs to be added. Once the clean has been completed, add the bottle of System Neutralizer until the solution turns yellow. If the water is still red, more Neutralizer will need to be added. If the bottle supplied is inadequate, additional System Neutralizer can be purchased from Fernox stockists. The system must be drained down and flushed several times with fresh water until the water running to drain is clear. After the final drain, it is recommended that the system is inhibited using Fernox Protector F1. Not for use in single feed indirect cylinders, e.g. ‘Primatic’ or similar.

I had limescale in my furnace from a broken line that drained most of the liquid away while i was on vacation. the boiler boiled the liquid down to a condensate and I had serious kettling. I put this in for 6 hours, let it do its job followed by F-1 and the boiler is quiet as a church mouse.
