With old compressor off pour out oil if lees than 2oz. Add 4oz to new compressor. Accumulator 2oz. Oil. System oil is 8 oz. There will be oil left in Evap, condensor and lines. Recommend orfice tube especialy if old compressor shelled. Oil all O rings and threaded connections. Button up put on Vacuum pump for at least 2 hrs a little longer vwould not hurt.
Close gagues shut off pump let set 2 hrs. If no loss of vac then charge. 2lbs of 134A
