Application and Dosage
One 500 ml bottle of Cleaner F3 is sufficient to clean a typical domestic central heating system (average 3 to 4 bedroom house or 100 litres). Additional/repeat applications of Cleaner F3 may be necessary for larger 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. Motorised 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.
