6. SWITCHING OFF THE BOILER
To turn off the boiler, disconnect the electric power supply using the two-pole switch. In the “Off” operating mode the boiler stays
off but the electrical circuits remain powered and the anti-freeze function remains active.
7. FILLING THE SYSTEM
Regularly check that the pressure displayed on the pressure
gauge " D " 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).

D 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 pres-
sure is reached. Lastly, vent any radiators in the system. BAXI declines all liability for damage deriving from the presence of air bub-
bles 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.
8. ROUTINE MAINTENANCE INSTRUCTIONS
To keep the boiler efficient and safe, have it checked by the Authorised Service Centre at the end of every operating period.
Careful servicing ensures economical operation of the system.
