You only add refrigerant thru the LOW pressure valve. First check the pressure with a pressure gauge (should read between 25-45 psi) If low then start engin and turn AC on high. Attach refrigerant canaster to the low pressure valve to release refrigernt into the system. Canaster turns very cold and condensation appers on it as it releases into you a/c. Recheck pressure to make sure that is is at the proper PSI. You will hear the compressor kick on and off and the gague will fluctuate between the proper range.
