POWER FLUSHING PROCEDURE
Step 9) Individual radiator cleaning continued
Now turn off furthest radiator and move to next one, repeating (Step 8) on all radiators, working your
way back toward your Flowclean Plus. Once completed turn off boiler if you haven't already done so.
Step 10) Individual radiator dump
Once all radiators have been individually cleaned then start dumping individual radiators in reverse of
how you cleaned them. Again make sure you maintain water level and continue dumping each
radiator until dump water runs clear as in (Step 5).
Step 11) Neutralising system
After the dumping process is complete, turn valves back to recirculate on Flowclean pump and turn off
water inlet tap. Make sure all radiators are now open, to return to full system circulation. Now add
neutralising agent to system, again using your chemical funnel on the front of your tank. Leave
circulating around full system for 15 minutes.
Step 12) Final dump procedure and pH test
With all radiators still open complete final dump procedure (as in Step 5), maintaining water level and
continue dumping until dump water runs clear or for approximately 10 - 15 minutes. You will now need
to test the pH levels to check dump water is now neutral, this should read the same as a sample from
the mains water supply to the building. pH paper or electronic pH meters can be used.
Step 13) Adding inhibitor / system protector
You can now add your inhibitor / protector to the system, either using your chemical funnel at the front
of your tank or injecting into a radiator or open pump valve. (Please note you may need to drain a little
water out of system to achieve this).
Step 14) Final procedure
Leave your Flowclean pump circulating for a further 10 minutes before disconnecting it and returning
system back to normal, in other words reinstate cold feed and vent pipe, make sure feed and
expansion tank is cleaned, replace pump or radiator, fully vent and test system, check for leaks and
return all valves to original position.
Step 8) Individual radiator cleaning
For best results all radiators should now be cleaned individually. Turn off all radiator valves on system
apart from furthest radiator, continue to recirculate through individual radiator for 5-10 minutes,
regularly reversing the flow. (obviously always making sure at least one radiator is fully open at any
one time).
