CHEMICAL FLUSHING PROCEDURE USING HYPER-FLUSH
1. Switch on the Quantum.
2. Whilst re-circulating water through the Quantum
and the heating system, slowly add
1 litre of HYPER-FLUSH to the Quantum tank,
sufficient for 10-12 radiator system, (unless it was
added on a prior visit), and ensure thorough
distribution around the system.
3. Switch on the boiler, if fitted, and in safe working
order. Allow the system water to reach 50°C, and
then switch boiler off.
NOTE: Even boiler thermostat setting no.1
could exceed 50°C.
4. Circulate throughout the complete system for half
to one hour, reversing the flow direction regularly,
and monitoring the system for leaks.
5. Close off all radiators (one valve only), and allow
the full flow to go through the coil in the cylinder
(if present in the system).
6. Reverse the flow regularly.
7. Divert the full flow to the radiator circuit, in
preparation to putting the full flow of the Quantum
through each radiator in turn.
8. Fully open both valves of the nearest radiator, on
the ground floor, to the Quantum.
9. Flush this radiator, reversing the flow regularly,
until all cold spots have disappeared, and the
temperature across the radiator is consistent.
Close the radiator valves.
Note: If your initial system check identified cold or
partially blocked radiators, commence the
individual radiator flushing procedure with the
worst radiator first, progressing to less
problematic radiators. This ensures that the
strongest concentration of chemical is directed at
the worst areas of the system.
10. Open the valves on the next radiator, and repeat
the procedure.
11. Work through the rest of the radiators in turn, so
that you have flushed every radiator individually,
including upstairs radiators.
12. When you have flushed the last radiator, and it
has an even temperature across the surface,
switch the Quantum into dumping mode, as
previously.
13. With only this radiator open, and the Quantum
set to dump, run until the water leaving the dump
hose is completely clear. Now operate the flow
reverser and change the valves to dump in the
opposite direction until clear. When dump water
is clear, close radiator valve.
14. Go back to the previous radiator that you had
flushed, ensure both valves are open, and repeat
the dumping procedure on this one radiator,
alternating the direction of flow in each direction
as you dump. Close radiator valve.
15. Work your way back around the house in the
opposite direction to previously, until you have
carried out the dumping process on every
radiator individually.
16. Now with the Quantum still set to dump direct the
flow through the cylinder coil until it runs clear.
Dump in the other direction until clear.
17. If you have a TDS meter (Total Dissolved Solids)
it is useful to test the water at this stage.
The reading should be compared with a mains
water sample reading, and the dumping process
continued until both readings are within 5% of
each other.
18. Return the Quantum into normal re-circulation
mode, re-open all radiator valves, and the
cylinder coil, and move to page B.10..
19. NOTE: When using HYPER-FLUSH, there is no
requirement to neutralise after the flushing
process.
