One single dose of Fernox Protector F1 Express treats and protects a larger sized property with a heating system of 34 US Gallons of system water (16 radiators) and the equivalent of 2690 sq ft of underfloor heating and can be dispensed directly into a radiator air vent, system filling loop, or via a TF1 Filter using the appropriate adapter supplied with the product. Fernox Express takes less then 30 seconds to dose the system without the need to drain down the system, saving time on-site. If dosing via a TF1 Filter, the filter should be emptied of any collected contaminants prior to treating with the product. In single feed indirect cylinder, e.g. Primatic; or similar, potable water chemicals must be used. Fernox recommends untreated or sludged systems are thoroughly cleaned and flushed in accordance with local regulations and legislation, using Fernox Cleaner F3 Express, before treating with Fernox Protector F1 Express, as existing debris can damage the installation.

Fernox Cleaner F3 Express is also designed to be used in conjunction with a powerflushing unit. In this case, please refer to the unit manufacturer’s instructions. When using Cleaner F3 Express with a powerflushing unit, cleaning should be completed within an hour. Use dynamic flushing with plain water until the water is clear, testing with a TDS meter to ensure thorough flushing. Refill the system adding a suitable Fernox Protector for long term protection against corrosion and limescale. In single feed indirect cylinders, e.g. ‘Primatic’ or similar, potable water chemicals must be used.
