Thanks Brucey,
I found behind the control panel what could be an integral fill-loop with a small white plastic cock one end and a sprung twist knob the other marked 3 bar. My guess would be fit a hose, open up twist away, watch the guage and see if it 'likes it up-em mr manwaring'! Seriously though, am I getting any closer? Do I need to close any isolators etc before filling?
Appreciate the help.
