I am about to recharge my system after buying a vacuum pump and gauges. I want to try the ES-12a but Im not sure how much I need for a evac and recharge. The BGB says ~30 ounces and the ES website says one 6 ounce can = 18 onces of alternative R12. Should I charge by weight or by low side pressure. Not sure how many cans I need to buy.
