POWER FLUSHING PROCEDURE
Step 1) System preparation
Isolate power to heating. If the system to be cleaned is vented, firstly you will need to cap off the
cold feed and the vent pipe or create a temporary loop. These will obviously need to be reinstated
after power flushing. (See page 3
for further detail).
Step 2) Flowclean connection
Connect your Flowclean pump to the heating system, most commonly done at the circulating pump or
by taking off a conveniently positioned radiator. Connect all hoses, flow & return, dump, overflow, cold
water inlet and magnetic filter, isolate power to circulating pump (see pages 3 & 6
for further detail).
Step 3) Valve preparation
To ensure maximum flow rate throughout the system, open all the radiator valves and set any zone
valves to manual open. Check for anti-gravity check valves (see page 3 for further detail).
Step 4) Start cleaning
Firstly make sure your tank is approximately 5cm above minimum level indicator with clean water,
using the water inlet tap. Make sure both valves are set to recirculate, now you can switch on your
Flowclean pump. Leave circulating for approximately 15 minutes, regularly reversing the flow.
Step 5) Dump procedure
Now dump initial contaminated water from system. Set right hand valve (return) to dump position
whilst making sure your water inlet balances with what you are dumping out, maintain water level in
other words. Continue dumping until dump water runs clear.
Step 6) Back to recirculation & adding chemical
Now set right hand valve (return) back to recirculate and turn off water inlet valve, continue to
recirculate with all radiator valves open. Now add flushing chemicals to system using your chemical
funnel on the front of your tank.
Step 7) Heating water
To assist with the power flushing process (if achievable) fire up the boiler and heat water to
approximately 50ºC, (
making sure that electrical supply to pump has been isolated
) be sure not
to leave boiler on continuously. Continue to recirculate water through the whole system for a further
15 minutes, regularly reversing the flow.
Please note: Supameg Magnetic in-line filter maintenance
During the cleaning process you will need to keep your eye on the in-line magnetic filter as this will attract iron
oxide particles during the procedure and gradually become choked. To empty simply turn off power switch to
unit, set right hand valve (return) to closed position (make sure flow direction of water is returning down the
return hose) remove the magnet from top of the filter, open the small drain tap over bucket with small length of
hose attached, turn on power switch and drain debris into bucket. Once completed turn off power switch, close
drain tap, replace magnet, set right hand valve (return) back to recirculate and continue with cleaning procedure.
