HELPFUL SUGGESTIONS
To get the most out of your boiler, we have provided you with some useful advice on
proper use and maintenance:
- Periodically check the system pressure using the pressure gauge
“D”, make sure that
the pressure is at 1.5 bar when the system is off and cool. If the pressure is below the
minimum recommended value (1 bar). To refill the system, open the two black handles
connected to the silver flexible hose, once the pressure gauge
“K” reads 1.5 bar close
the valves again.
NOTE:DO NOT UNDER ANY CIRCUMSTANCES USE THE APPLIANCE WITH THE PRESSURE GAUGE
