Fernox Cleaner F3 is a quick and effective pH neutral cleanser for central heating systems. It is

designed to remove all debris, sludge and scale from existing systems of all ages. In this way, it will

restore heating efficiency and eliminate or reduce boiler noise. It has also been designed for pre-

commission cleansing new installations in accordance with BS7593:1992, removing flux residues

and other debris, thereby helping extend the life of a system.

For older sludged systems, Cleaner F3 is particularly effective when used in conjunction with a

powerflushing unit. If the system is heavily scaled the use of Fernox Superconcentrate System

Cleaner is recommended. Cleaner F3 is a neutral, non-hazardous product that is well inhibited and

compatible with all metals and materials commonly used in heating systems.

For continued long term protection the system should be thoroughly cleansed and flushed in

accordance with BS7593:1992 and Benchmark using Fernox Cleaner F3, before treating with Fernox

Protector F1. We recommend Protector levels are checked regularly (annually).

Application

One 1 pint container of Cleaner F3 is usually sufficient to clean a typical domestic central heating system. Additional/repeat applications of

Cleaner F3 may be necessary for large systems, or if systems are heavily sludged.

First drain and refill the entire system with plain water. For optimum results the entire system, including drop feed radiators where fitted,

should be completely drainable. Preferably full bore gate valves with hose connectors should be provided temporarily for this purpose.

Motorized and thermostatically controlled valves must be set so that no part of the system is closed off during cleansing or rinsing.

Discharges must be made to the foul drain and not the surface water drain.

For open vented systems add Fernox Cleaner F3 via the header tank. For sealed systems add via a radiator using a Fernox Injector. Fernox Cleaner F3 can also be used in conjunction with a powerflushing unit. In this case, please refer to the unit manufacturer’s instructions. When pre-commission cleansing new systems, Fernox Cleaner F3 should be circulated for a minimum of 1 hour at normal operating temperature.
