If the dip test shows less than 100ppm, installers can immediately resolve the issue by adding a high-quality inhibitor such as Fernox Protector F1 or where a filter is fitted, Protector+ Filter Fluid. The test can be re-taken once the inhibitor has circulated to confirm the level has been met.
When I dose with Boiler Noise Silencer F2, do I also need to use a Fernox Protector?
Yes, Fernox Boiler Noise Silencer F2 is designed for use with any Fernox Protector. It should be left permanently in the system with Protector F1 or Protector + Filter Fluid and replaced or topped up at the same time.
