Alternatively, by pre-dissolving in warm water, the product can be applied via a suitable dosing point on the system. One container (25 kg) is usually sufficient to treat 1600 litres of system water. For very large or heavily scaled or sludged systems, additional powder or multiple drums may need to be added. During the early part of the clean, a colour change (red-yellow) indicates that the product is exhausted and more powder needs to be added. Once the clean has been completed, add System Neutraliser until the solution turns yellow. If the water is still red, more System 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 is inhibited using Fernox HVAC Protector F1 or Fernox FC1 Inhibitor.Not for use in single feed indirect cylinders, e.g. ÔPrimaticÕ or similar.
