I find nothing that Frank posted to be inaccurate. But I will ask "how much" refrigerant you have put in? Are you using R12 or something else? MAKE SURE YOU ONLY CHARGE THRU THE LOW SIDE (if doing it with the engine running). MAKE SURE you are wearing eye protection. Also please explain "system was disconnected, but still sealed, with pressure"...
