Several major manufacturers are producing comfort air conditioning equipment using refrigerant 410A. The trend towards the use of R-410A continues to grow and there is a demand for technicians who are comfortable working with this higher-pressure replacement for refrigerant 22. Due to the differences between R-22 and the newer ...Well, you can't charge to the high side. It should be obvious that the output of the compressor is going to be a higher pressure than the R-410a in the bottle at ambient temp. I have never done R-410a yet but as I understand it you charge liquid to the low side but *slowly* as to allow it to vaporize on the way in so it doesn't slug the compressor.To charge a 410A condensing unit, follow these steps: 1. Turn off the power to the unit and ensure it is safe to work on. 2. Connect the refrigerant manifold gauges to …Most cracks on line sets aren't due to the method of joining copper, although silver brazing will be a weaker joint. They are due to poor design.
