I must clear up something about converting ACs to R134. I thourghly flush the system and use the ester oil that comes with the kit.I use a laboratory model vacuum pump. It is one we used in my lab and will almost reach a complete vacuum(30.00") I run the pump at least 4hrs. close all valves and let it set overnite. The next morning I will run the pump for another hour By this time there is nothing in the system. We don't hot weather like the folks in Tx.But is hot and humid here. If I remember my days in TX.,the weather was hot and dry. We sweat so much that we had to take salt pills.
