Yea, I didn't read far enough, but the manual makes no sense.
Says add per component replaced:
Condenser 30 cm3
Evaporator 60 cm3
Piping 10 cm3
Receiver/dryer 10 cm3
That totals more than the factory fill of 80 cm3, assuming that's all the oil added to the system. Instructions then say measure old oil poured from old compressor and deduct from 80 cm3, but that number includes oil in other components not replaced. Some oil will have escaped with bleed off of refrigerant. Not sure if each component also gets oil at factory as per above??
