Re-pressurising the System
1. If the water pressure is too low, the system must be
re-pressurised.
2. The normal operating water pressure is between 1 and 2 bar.
If the pressure exceeds 3 bar the safety pressure valve will
operate and a fault is indicated (E117 displayed). Ensure that
the filling loop is disconnected. Contact your installer.
3. It may be necessary to repressurise the system occasionally
(when the water pressure falls below 0.7 or E118 displayed). A
filling device (the filling loop) will be fitted on the system. This
will be on the boiler itself, or on pipework near to the boiler.
If the water pressure requires regular re-pressurising a
fault or leak is indicated. Seek advice from your installer.
4. If you are unsure of its position, or cannot identify it, consult
the installer who fitted the boiler.
5. The filling loop consists of two isolating taps and a separate
filling pipe with connection fittings.
6. Only when repressurising should the filling pipe be connected
between the two taps. Ensure that the nuts on the pipe ends
are tightened onto the taps.
7. Fully open one of the taps first, and then while watching the
pressure gauge, carefully open the second tap.
8. The system pressure is shown at all times on the pressure
gauge and can be viewed on the display when there is power to
the boiler.
9. To check the water pressure on the boiler display press
until is shown. This will alternate with the system
pressure. (When the pump is running the pressure gauge may
show a slightly different reading to the display).
10. When the figures on the display or needle on the pressure
gauge indicate between 1 and 1.5 bar turn both taps off.
11. Disconnect the filling pipe from the taps (a small amount of
water may be present) and remove it. Keep the pipe in a safe
place for future use.
12. If blanking caps are available fit them to the taps.

13. When the correct pressure is restored the boiler will reset
automatically.
