HVAC R22, 410A Refrigerants! Checking the Charge- Vapor/Suction Operating Pressures, What is Too Low! P/T Chart on the Manifold Gauge Set is Calculated. This video is how to tell if the Vapor pressure is too Low to wait for ten minutes for the system to run before checking the Refrigerant. You need to add refrigerant until the pressure is high enough so that the Evaporator will not freeze. We go over Saturation Pressures and Temperatures, What Baseline Pressures should be before even checking for Superheat or Subcooling. We examine R-22 first and then R-410A
Supervision is needed by a licensed HVACR Tech while doing this as Experience and Apprenticeship garners Wisdom and Safety.
