Application & usage:
2.5 litres of Power Flush FX2 should be used to treat a typical heating system of 100 litres capacity (approx. 10 radiators), and 5 litres should be used if the system has severe flow problems, or has microbore piping.
With all radiator and zone valves wide open, use the CLEARFLOW pump to mobilise relatively loose debris and corrosion deposits, and then purge them from the system through the dump valve. Close the dump valve and restore circulation through the CLEARFLOW and heating system.
Add Power Flush FX2 through the CLEARFLOW filler cap before commencing individual radiator flushing. FX2 may be used on a cold system, although firing the boiler for a few minutes after application of FX2 will cause the reaction to proceed faster.
Close radiator valves on all but one radiator, allowing full flow through this radiator for 5 minutes. Repeat for all other radiators and change CLEARFLOW pump to dumping mode. Continue dumping until waste water is absolutely clear.
After purging all debris to waste, add NEUTRALISING CRYSTALS to the CLEARFLOW tank and circulate for 5 minutes before a final purge, allowing waste water to run clear. Check the waste water with pH paper.
To prevent future corrosion of system, add SYSTEMSAFE-DM scale and corrosion inhibitor to CLEARFLOW tank and circulate through system for a further 5 minutes before disconnection. Use one litre per 100 litres system water content, or 1% dosage rate by volume.
REFER TO THE APPROPRIATE MATERIAL SAFETY DATA SHEET BEFORE USE.
CAUTION: Power Flush FX2 is acidic and, therefore, suitable protective clothing, gloves and goggles should be worn.
When using any acid, there is a possibility of flammable hydrogen gas being evolved, and the working area should be well ventilated. Avoid smoking nearby, or any other means of ignition.
