Power Flush FX2 is designed for use with CLEARFLOW® power flushing pumps, and is the flushing liquid to choose for the most rapid and effective results. It is a vigorous 'one shot' flushing and descaling liquid which starts to work immediately after addition to the system.

Power Flush FX2 enables heating engineers to thoroughly cleanse a heating system in just one visit, a significant benefit when so many households have both partners working full time.

When using Power Flush FX2 there is normally no need for a prior visit to pre-treat the system with flushing chemicals several days before the power flush, saving on expense and inconvenience.

Power Flush FX2 rapidly dissolves and mobilises the rust, sludge and corrosion deposits which accumulate in the systems as a result of gradual decay, whether from corrosion as a result of bad design and air ingress, or lack of an effective corrosion inhibitor.

Removal of these deposits can cure or prevent circulation problems such as completely or partially cold radiators, frequent circulating pump failure and boiler noises caused by debris accumulating in the heat exchanger.

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 if the system has severe flow problems, or has microbore piping.

FIRST STAGE:

With all radiator and zone valves wide open, use the CLEARFLOW® pump to mobilise and 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.

SECOND STAGE:

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 for5 minutes. Repeat for all other radiator sand 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.
