In this HVACR Training Video, We Show what is done to Retrofit an Existing R-22 Air Conditioning System to R438A/M099. During the Procedure, we use the DANFOSS REFRIGERANT SLIDER APP to Check the Charge while Weighing in the Refrigerant. I also go over the Disconnect Procedure, Leak Testing the Schrader Valves, and the Installation of Locking Caps. Supervision is needed by a licensed HVACR Tech while doing this as Experience and Apprenticeship garners Wisdom and Safety.
