Product Description

Cleaner F3 Express is an aerosol product designed to make dosing a system quick and simple with no

mess or inconvenience to the user. As with all Fernox Cleaners, Cleaner F3 Express

is an effective neutral

cleaner.

Cleaner F3 Express has been designed for pre-commission cleaning of new installations in accordance with

BS7593, removing flux residues and other installation debris, to help extend the life of a system.

Cleaner F3 Express can be used in conjunction with Fernox Powerflow MKIII powerflushing machine and all

known makes of powerflushing machines to remove all debris, sludge and scale from existing systems. In

this way, it will restore heating efficiency and eliminate or reduce boiler noise in heavily contaminated

systems.

Cleaner F3 Express 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 cleaned and flushed in accordance with

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 the TDS meter as above to ensure through 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. First drain and refill the entire system with plain water.
