LOSS OF SYSTEM WATER PRESSURE
The gauge (G) indicates the central heating system pressure.
If the pressure is seen to fall below the original installation
pressure of 1-2 bar over a period of time then a water leak
may be indicated. In this event 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 boiler will display "Low water pressure" -
"1 fill system to 1.0 bar"
"3 Contact installer" .
To re-pressurise:
1.
Ensure filling loop isolation valves are closed.
2.
Remove the left hand cap.
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 1 to 1.5 bar.
6.
Close the filling loop isolation valves.
7.
Disconnect the filling loop at left hand side and angle
upwards.
8.
Replace cap.
