Cleaner F3 Express
Cleaner F3 is an effective, universal pH neutral, non-foaming cleaner, which removes sludge, scale and debris from existing central heating
A simple and easy-to-use turbidity test to check the quality of system water and determine appropriate treatment to ensure the system works at optimum efficiency, and the boiler is fully protected.
Fill the tube with a 50 ml sample of system water taken from either the boiler or a radiator. Look down the tube and focus on the black and yellow target at the base of the tube. Depending on the cleanliness of water, there are 4 recommended treatment options;
1. The target is clearly visible and the system is adequately inhibited (with the boiler displaying a retreatment label) – No action required
2. The target is clearly visible but the system may not be adequately inhibitor (no retreatment label is displayed on the boiler) – Dose with Fernox Protector F1
3. The target is visible but blurred indicating contaminants are present in the system water – Fit a Fernox TF1 Filter and dose with Fernox Protector+ Filter Fluid
4. The target is not visible indicating a heavily sludged and dirty system due to corrosion and limescale formation – Clean the system with Fernox F3 Cleaner or Fernox Power Cleaner F8, fit a Fernox Filter and dose with Fernox Protector+ Filter Fluid
