Hooked up and running. Question is how much R290 to put in?? I think I saw some thing about put in around 60%. I put in 2lbs 5oz, but lost some disconnecting the line( it's dam cold stuff). I check the inlet temp at the A-frame 48°F with the outlet at 56°F. The air from the duct was 57°F and the outside air temp was 76° F. The pressures were 58/160. Any suggestions will be welcome.
