Pumped it back down again for an hour, then held vacuum for an hour.
I used Freeze 12 to charge it with my R12 gauges and a side can dispenser. Low side was 76 PSI and the high side was 225 PSI.
I'm getting 50-60* out of the center vents on a 85* sunny day. I was hoping for colder, but I'll see if it lasts and go from here. Any ideas on making it colder?
One thing I had to do was add a drop of solder to the tip of the schrader valve. I replaced it with a new one, but it was still just low enough the hose fittings wouldn't push it down to pump or charge.
