I have a sabre 25 combi boiler, how do i increase the water pressure?

this boiler dosen't have a filling loop it has an internal filling valve which you will need a key for, which the home owner should have. under the front left corner is the slot for fitting the key. insert the bayonet into the cut out of the filling device and turn to lock the key in place. turn anti clockwise to fill to 1.5 bar.

Open the cold water mains filling loop fitted below the boiler and increase pressure to 1.5 bar close when pressure reached.
