The TF1 Total Filter can be connected directly on to the pipework using the valve fittings provided. The TF1 Total Filter can be installed in any one of 24 separate orientations enabled by its unique inlet/outlet mechanism. The TF1 Total Filter (UK patent granted No. 2448232) is a revolutionary in-line filter, which combines Hydrocyclonic action with specially designed magnet assemblies, to remove both magnetic and non-magnetic contaminants from system water and contain safely within the filter before removal.
The TF1 Total Filter can be installed on vertical or horizontal pipework, in accordance with the flow direction indicated by the arrow on the manifold. Ideally the filter should be fitted on the return to the boiler and can be installed at up to 45⁰ from the vertical position if space or head height is restricted.
The recommended ‘in use’ concentration of Protector+ Filter Fluid F9 is 0.385%. A single dose of this product treats and protects a larger sized property with a heating system of 100 litres, up to 12 radiators or 190 sqm of underfloor heating. For open vented systems add via the feed and expansion tank. For sealed systems add via a suitable dosing point (e.g. a towel rail, or an in-line system filter). Alternatively, use a suitable dosing vessel to inject the product into the system. In single feed indirect cylinders, e.g. ‘Primatic’ or similar, potable water chemicals must be used. We recommend that untreated, or sludged systems are thoroughly cleaned and flushed in accordance with BS 7593:2019 and Benchmark using Fernox Cleaner F3/F8, before treating with Fernox Protector+ Filter Fluid F9, as existing debris can damage the installation. Fernox Protector+ Filter Fluid F9 must be used with the Fernox TF1 Filter range, or other in-line system filters. Use in microbore systems is not recommended.
Fernox Protector+ Filter Fluid F9 is an enhanced corrosion inhibitor, combining corrosion inhibition with dispersant properties. It is specifically formulated to prevent setting and aggregation of corrosion deposits and contaminants within central heating systems, to deliver the debris directly to an in-line filter (such as one from the Fernox TF1 Filter range) for fast removal and containment. This function allows systems to run more efficiently by minimising the settling of debris in low flow areas such as radiators, which causes cold spots and facilitates further corrosion underneath the debris.
Protector+ Filter Fluid F9 gives long-term protection of domestic central heating systems against internal corrosion and limescale formation. It is suitable for all types of boiler, radiators and pipe work systems. Protector+ Filter Fluid F9 is compatible with all metals and materials commonly used in central heating systems. It is suitable for use with all types of water, including softened water and deionised water. Protector+ Filter Fluid F9 has been formulated to have best-in-class pH buffering ability, which keeps system water pH between 6.5-8.5, giving optimum protection for mixed-metal systems. To comply with BS 7593:2019, Protector+ Filter Fluid F9 levels should be checked annually. The concentration of the product can be easily measured on site using a Fernox Protector Test Kit, or by using the Fernox Water Quality Test postal service. BS 7593:2019 also states that after 5 years, systems should either be re-dosed, or a laboratory test performed, such as the Fernox Water Quality Test.
