Calculating superheat: Measure the low-side pressure with your gauge. Convert pressure to temperature with an app, slide or chart. Next, take the temperature of the suction line where it leaves the condensing unit, though stay 4-6 inches from the compressor. Use your measurements to determine the amount of superheat.

R-407C is a zeotropic blend of R-32 (Difluromethane), R-125, and R-134a (Tetrafluoroethane). It is not a drop in replacement on R-22 machines. If you wish to use this product you will need to vacate all of the old R-22 out of the system. This is due to the R-22 systems using mineral oil and this HFC blend using POE oil.R-410a Superheat & Subcooling Calculator.
