How do you raise the pressure in a Vokera Excell 80SP?

on the cold mains supply to the boiler there should be a branch tee-piece, with a stop tap and flexible connection to the pressurised side of your boiler. by gently opening that valve you should see the pressure on the gauge increase to the pressure you require. once the pressure is reached you must turn the valve off again. the flexible tube may be diconnected; but mostly they are not;
