In This HVAC Training Video, I show the Front Seat and Fully Open Positions of the Common Two Position Service Valve found on Air Conditioners and Heat Pumps. This Valve does not technically have a Back Seat position. I discuss the Schrader valve core and accessing the port to read pressure. I also discuss the pump down of a system. Supervision is needed by a licensed HVACR Tech while performing procedures as Experience and Apprenticeship garners Wisdom and Safety. Make sure that you EPA 608 certified before handling refrigerants!
