R22 low side pressure at 70 degrees.

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.Price$26.80.

Methods that can be used to properly charge a system include: 1. Total Superheat Method (Fixed Orifice / Piston / Capillary Tube / Non-TXV) Temperature must be above 55°F outdoors and above 70°F indoors with a indoor wet-bulb temperature above 50°F The evaporator coil cannot operate below freezing or an overcharge and possible compressor damage could result.

Although it's really impossible to say what the "normal operating pressures" are for an R410A system as it's based on so many variables:load, humidity, condition of outdoor coil (clean or dirty), I would expect to see 120-135 on the low side and about 280-300 on the high side. Again, these are just examples.One of the first refrigerants to go was our friend R-12. At this point in time, in the early 1990’s, R-12 had seen the majority of it’s usage in automobile air conditioning. R-12 was banned in new automobiles and was replaced with by the HFC refrigerant we all know today as R-134a. Now, there are still some R-12 applications out there today.
