Dang you guys must love listening to all the e-knowitalls who post on other web sites...
It is NOT a sealed system. Yes it can be purchased as a complete system, pre-bled, but im sure its for people who can't read or follow directions on how to bleed something.
From the link you posted above.
#1 is a roll pin if you push that out the metal tube/hose nipple will slide out. It is O-ringed so its a pretty simple setup.
#2 is an allen head set screw bleader. Metric IIRC its 5mm. you can bleed from that point...
Note: I have a factory slave and a brand new setup in a box made by Sachs (sp) both have the bleed ports... Sometimes they will with crud or rust, its a small allen wrench.
