Fruita CO | I think you may be overcharged. If the 3.5 lb. spec was for R12, it will only take about 2-2.5 lb. of 134. It's real easy to overcharge 134, you can't go by the sight glass, it will be overcharged by the time the glass clears. 275 is usually about max. for the high side...
Everything I've ever heard or read says to flush when converting, I don't know why Sanden would say not to....
