It may be necessary to repressurise the system occasionally (when the
water pressure falls below 0.7). A filling device (the filling loop) will be fitted
on the system. This may be on the boiler itself, or on pipework near to the
boiler.
PN-0000373
Important
If the water pressure requires regular re-pressurising a fault or
leak is indicated. Seek advice from your installer.
Depending on which filling loop is fitted, a temporary filling loop consists of
two isolating taps and a separate filling pipe with connection fittings.
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.
1. Fully open one of the taps first, and then while watching the pres­
sure gauge, carefully open the second tap.
Important
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 boil­
er.
2. When the figures on the display or needle on the pressure gauge in­
PN-0000386
dicate between 1 and 1.5 bar turn both taps off.
3. 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 fu­
ture use.
4. If blanking caps are available fit them to the taps.

cally.
