4.0 Repressurising System &
'Service Due'
4.1 Central Heating System Pressure
1. The normal operating water pressure is between 1
and 2.5 bar (Fig. 1). If the pressure exceeds 3 bar the
safety pressure valve will operate and a fault is indicated
(E117 displayed). Contact your installer.
2. It may be necessary to repressurise the system
occasionally (as Fig. 2 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.
3. If you are unsure of its position, or cannot identify it,
consult the installer who fitted the boiler.
Note: It is recommended that repressurising is
performed when the boiler & system are cool.
4. The filling loop supplied consists of two taps and a
separate copper pipe with connection fittings.
5. Only when repressurising should the copper pipe be
connected between the two taps. Ensure that the nuts
on the pipe ends are tightened onto the taps.
6. Fully open one of the taps first, and then while
3
watching the pressure gauge, carefully open the second
tap.

7. The system pressure is shown at all times on the
gauge under the boiler and can be viewed on the display
when there is power to the boiler.
8. To check the water pressure press
displayed. This will alternate with the system pressure.
(NOTE: When the pump is running the gauge under the
boiler may show a slightly different reading to the
display) .

9. When the needle on the gauge or figures on the
display indicate 1 or more turn both taps off.
4
10. Disconnect the copper 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.
4.2 'Service Due' Message
