LOSS OF SySTEM WATER PRESSURE
The gauge (K ref page 6) indicates the central heating system
pressure. If the pressure is seen to fall below the original
installation pressure of 1-2 bar then conduct the re-pressurising
procedure as shown below. If unable to do so or if the pressure
continues to drop a Gas Safe Registered Engineer or in IE a
Registered Gas Installer (RGII) should be consulted.
THE BoILER WILL noT oPERATE IF THE PRESSURE
HAS REDUCED To LESS THAn 0.3 BAR UnDER THIS
ConDITIon.
In this case the following display will appear:
Low Water Pressure
Fill System to 1 Bar
Bleed Radiators
Refill System to 1 Bar
To re-pressurise:
1.
Ensure filling loop isolation valves are closed.
2.
Remove the left hand caps.
3.
Attach on the filling loop.
4.
Turn the filling loop isolation valves to the open position.
The system will now fill.
5.
Wait for pressure gauge to reach between1 to 2 bar.
6.
Close the filling loop isolation valves.
7.
Disconnect the filling loop at left hand side and angle
upwards.
8.
Replace caps.
