As I added gas the area of the coil releasing heat elevated on the coil. When I started initially heat was coming from the bottom 5 inches or so as I added gas this area raised until I got close to the top. The Klimaire has a large reserve container (nearly as big as the compressor) and I felt safe at that point.
Too bad there were no instruments to measure before & after. But good info on your technique for finding the optimum charge.
