7.0 Repressurising System

7.1 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.
Contact your installer.
2. It may be necessary to repressurise the system
occasionally (Fig. 2). 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.
4. The filling loop 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
watching the display on the i-THINK or pressure gauge,
carefully open the second tap.
7. When the display or needle on the gauge is indicating
1 or more turn both taps off.
8. 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.
