Ferroli F24 Boiler

[Jacko439]

My daughter as a Ferroli F24 Boiler which apparently is causing problems due to low water pressure. My daughter lives on her own and has asked me if I could re-pressurize it for her. I however am not a plumber but understand this would be a simple matter to put right if only I knew how. Could anyone out there point me in the right dirrection in simple language. Any help would be gratefully received

The manual states that you'll need a filling loop
