You need the first gen side.

Static pressure for the Ac should be 70psi and may be higher depending on outside temp. Operating pressure 25-35 on low and 200-300 on high, but perfect amount of refrigerant in the system can not be determined by mesuring pressures . Its done by weighing during fillup. Being slightly off with ref. wont change anything as most of the gas sits in receiver/dryer that works as sort of buffer
