CHEMICAL FLUSHING
PROCEDURE USING SENTINEL
X800 FAST ACTING CLEANER
1. Switch on the JetFlush pump.
2. Whilst re-circulating water
through the pump and the
heating system, slowly add 1 litre
of Sentinel X800 Fast Acting
Cleaner to the JetFlush Rapid
tank, sufficient for 8 – 10 radiator
(count double radiators as 2)
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 pump through
each radiator in turn.
8. Fully open both valves of the
nearest radiator, on the ground
floor, to the flushing pump.
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.
