Water system pressure adjustment
The filling pressure with system cold, read on the boiler water gauge, must be approx. 1.0 bar. If the system pressure
falls to values below minimum, the boiler card will activate fault F37 (fig. 16).
Operate the filling cock (detail 1 - fig. 17) and bring the system pressure to a value above 1.0 bar.
A pressure gauge (detail 145 - fig. 29) on the bottom front panel of the boiler displays the pressure even if the unit is not
powered.
Once the system pressure is restored, the boiler will activate the 120-second air venting cycle (AIR PURGE
A
function) indicated on the display by FH.
At the end of the operation always close the filling cock (detail 1 - fig. 17)
