Hi I am not seeing the step for the vacuum pump pulling -30 for 1 hour. You should see all moisture burn off(so to speak in a mist). R12 may be different but I didn't think recharging the system was different. Here is my gauge readings after I recharged with 234. This seems to work good. Good Luck
Yes of course 134 , get the lbs right and you should be there.

Yeah, I know.....Gonna do a heater core bypass valve also. Even though the heater may be "off", I have done that to past vehicles and works well.
Sometimes one could get "residual/radiated" heat in the heater/evap box even though heater is off and this eliminates that completely...Just open it back up during winter and it works normally.
Well, in between long periods of rain that are lasting 2+weeks, I dragged out my recovery tank and gauges and started siphoning off the excess refrigerant as mentioned previously.
I did this in short bursts and let system stabilize, playing with the pressures/evap temps until I could get them as low as I could w/out freezing the evap and, with this high humidity, that was no short task. The gauge readings came down nicely.
I don't know how much I took out and I will have to weigh the tank to determine this. Accumulator tank sweating "nicely" but, will still have to wait until I get this back on the road and test this in the typical temps of 92 - 96* here in Florida. I still have to repair bad brake line(s) going to abs near LR wheel.
