To restore the water pressure inside the system
open the loading tap “R” (fig. 1) and make sure
using pressure gauge “M” (fig. 1), that the system
pressure reaches 1.2 bar (see fig. 2).
After performing this operation, make sure that the
loading tap “R” (fig. 1) is properly closed.
After the water pressure reset the boiler will
automatically perform a 2 minutes system relief
