CALLING IN THE AUTHORISED TECHNICAL SERVICE CENTRE
If the symbol appears on the display together with the symbol , contact the AUTHORISED TECHNICAL SERVICE CENTRE .
Before calling, note down the fault code/s and the short message accompanying the fault.
If a fault code is displayed that is not included in the list or if a certain fault occurs frequently, contact the AUTHORISED
TECHNICAL SERVICE CENTRE.

8. FILLING THE SYSTEM
Regularly check that the pressure displayed on the pressure gauge B is 1 - 1.5 bar, with
the boiler cold. If the pressure is too low, turn tap “
A
” to fill the boiler (figure to side). Open
the tap very slowly in order to vent the air.
A Boiler/system filling tap
B
Pressure gauge
Take special care when filling the heating system. In particular, open any thermostat
valves in the system, ensure the water enters slowly in order to prevent the formation
of air inside the primary circuit until operating pressure is reached. Lastly, vent any
radiators in the system. BAXI declines all liability for damage deriving from the presence of
air bubbles in the primary exchanger due to the incorrect or imprecise observance of the
above.
The boiler is fitted with a hydraulic pressure gauge which prevents the boiler from
working if there is no water.
If pressure drops occur frequently, have the boiler checked by the AUTHORISED
TECHNICAL SERVICE CENTRE.
