Application & Dosage

For detailed instructions on carrying out cleaning of central heating systems using DS40 System Cleaner and Neutraliser, 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 an Injector into a radiator. One container (2 Kg) is usually sufficient to neutralise one container (1.9 Kg) of DS40 System Cleaner after cleaning the central heating system. The system water (after allowing any debris to settle) should be yellow in colour. If the water is still red, more neutraliser will need to be added. 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 be protected using a suitable Fernox Protector. In single feed indirect cylinders, e.g. ‘Primatic’ or similar, potable water chemicals must be used.
