How can I re pressurize my Potterton performa 24?

thank you so much Tony for your help, can't seem to locate chrome flexible hose, only small plastic hose coming out of central silver component.
Other 2 pipes going up to boiler are copper, (one of which has the reset switch)

there are no obvious valves? only large silver screw or two smaller ones on left of this central silver component

look for chrome flexible hose on pipework leading to boiler one to two of the pipe,one end you will find valve required to refill systemlinked 'not the ones directly under boiler
