Incorrect functions are signalled by the diagnostic
indicator LED 31 display flashing. Contact your local
authorised Servicing Centre (unless a low water fault is
indicated, in which case refer to Section 7 for filling
instructions).
A method for initially filling the system and replacing lost
water during servicing and initial filling (in accordance with
current Water Regulations), is provided as an integral part
of the connection kit (see Fig. 7.1).
To fill the system and replace lost water it is necessary to
proceed as follows:
- Switch off the power to the boiler;
- Ensure that the flexible hose is connected to both the
cold water inlet connection and the C.H. flow
connection;
- Open the black lever on the valve for the C.H. return
connection and slowly open the black handle on the
valve for the cold water inlet until water is heard
passing through the valves;
- Once the pressure gauge 33 (Fig. 6.1) reads between
1 and 1.5 bar close the levers on both the cold water
connection and the C.H. return connection
- Switch the power to the boiler back on.
