About using the quick release fittings - my manifold set with quick release ends is for R134 fittings (I also installed a micron vac gauge on the manifold, using a t-adapter, as that is what the instructions for my Mitsubishi specified), and I found that the service port fittings on the mini split are the same as R12 fittings, so I simply used an R12-to-R134 quick release conversion adapter (that adapter has a rod in it that depresses the service port manifold valve core when the quick release hose end's knob is turned). That worked perfectly (I tested it with both vacuum and pressure before using it in earnest). I hope that jibber jabber makes sense.
