In the online manual, the bleeder is described as "Connect/disconnect control". They only show the older plastic tank radiator and not the aluminum tank.

By "bleeding" I understand "connecting both sides of the radiator to remove air", not purging all the refrigerant out.
Sorry for this explanation but sometimes different languages can frame us out...
Here it is.
This one is the old plastic covers model (sometimes the "transmission side" got blocked and the transmission oil starts to heat and then it became replaced by the alluminium covers model).
#31 is the bleeding valve
This is the new full alluminium model, witch replaced the old plastic covers model and became serial from some PIN onward.
#22 is the bleeding valve, in the bottom, located in the front side. You'll find the base plate to have a lower part, clean it and you'll see the allen wrench plastic screw.
