I am converting to 134a and am using a sanden 508 that I was running r12 in. The guys at Vintage air told me to pull the drain plug and turn upside down overnight, I didnt get much out and they said to add 7.2 oz. of PAG 100 to it . I'm assuming they meant to put it back in the oil drain and reinstall the plug? Or am I supposed to add it to the suction and discharge ports?
Add your oil thru the drain plug.......
