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 " 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).
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.
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.
