INHIBITION AND CORROSION
PROTECTION

IMPORTANT

1. The system is now full of fresh,
clean water, and in line with
Building Regulations Part L
Compliance Guide, a good quality
corrosion inhibitor, such as Sentinel
X100 Inhibitor, must be added to
the system water to prevent further
corrosion and scaling.
To comply with Benchmark
documentation, inhibitors must
have passed the Buildcert CIAS
Scheme product performance
standard and can be identified by
this logo on the pack.

UPON COMPLETION

1. Restore system to normal,
restoring radiator balance valves
to original settings, removing any

temporary isolating valves or caps
on the expansion and cold feed
pipes, and restoring non return
valves to normal operation if
necessary.
2. Before re-connecting the feed
& expansion tank, it should be
thoroughly cleaned, removing all
traces of dirty water and sludge,
and disinfected if necessary.
The inhibitor may be added to
the system by using the JetFlush
pump as follows:
3. Briefly open a dump valve to lower
the water level in the tank to just
above the minimum level, close
the dump valve. Add the Sentinel
X100 Inhibitor into the tank. Allow
circulation through the system for
ten minutes, isolate the flushing
pump from the heating system,
and switch off.
4. If the system is vented, the
residual water in the JetFlush
tank, which will contain a small
quantity of inhibitor, may be
poured into a bucket and added to
the F&E tank after this has been
cleaned.
NOTE: In a pressurised system
the inhibitor may be injected into
the system using an injector,
which will avoid wasting any
inhibitor left in the tank.
