HVAC Refrigerant Pump Down with an R410A Compressor that has a Bad Internal Pressure Relief!
In this HVAC Video, I go over the Refrigerant Pump Down of an R410A Outdoor Unit with a Compressor that has a Bad Internal Pressure Relief Valve. I show the procedures for preparing a pump down and why this compressor could not handle the pressure. I explain the difference between a pump down and a recovery and why we use each.
