There no howto but although it'd bloody awkward it's quite straight forward. Remove all the 'bagpipes' from the front of the engine because that the direction the compressor will be taking. It's held with five bolts, 3 at the front by the fan belt & 2 at the back of the compressor. The in/out pipe work is held to the compressor via a single bolt - I slackened this from the top using about 2' of extension bars (15mm or 16mm IIRC  :-/) After you've disconnected the single plug from the side, it should come out. I'd recommend you have the car as high up in the air as you can ....... ramps were the best I had.

I thought the compressor should be extracted with the pipes attached, as it has no room to go out...

As above.....long extension from above to remove the one bolt holding the pipes to the compressor.
Undo mounting bolts and bolt fixing pipe clip near front of compressor.
Ease the compressor forward and rotate one way, and then the other to clear the filler plug and connector from obstructions.

When refitting, the pipes must be in position before sliding the compressor in. Get the compressor home and fit the pipes and bolt before fitting the compressor fixing bolts.
You can just get a hand to the pipe fixing plate from underneath, reaching over the engine mount.

You are right, I replaced two years ago the front bearing from comp. and both, pipes and comp. came outside together, just enough to remove the bolt. And yes, replace both o-rings. Must have some pic somewhere.... ;)
