Weigh in the initial charge and ensure a proper vacuum was achieved. Adjust sensors or set points to operate the compressor continuously while charging the system. Add refrigerant to allow the discharge pressure to rise to 325-420 psig. Physical Properties: R-410A has an atmospheric boiling point of -62.9°F [-52.7°C] and its saturation pressure at 77°F [25°C] is 224.5 psig. Composition: R-410A is a near-azeotropic mixture of 50% by weight difluoromethane (HFC-32) and 50% by weight pentafluoroethane (HFC-125).After all, these are the two variables we directly control in the heat pump cycle. What we want to understand is how increasing/decreasing pressure and adding/subtracting heat energy affects the temperature. The chart below shows the pressure vs. heat energy relationship of R410a at a constant temperature of 60°F.

These units use R-410A refrigerant which operates at 50 to 70% higher pressures than R-22. Use only R-410A approved service equipment. Refrigerant cylinders are painted a “Rose” color to indicate the type of refrigerant and may contain a “dip” tube to allow for charging of liquid refrigerant into the sys-tem.

LOCATION Check local codes for regulations concerning zoning, noise, platforms, and other issues. Locate unit away from fresh air …Suction Pressure/EVAP DTD Rule of Thumb Another common old-school rule of thumb is that suction pressure should be close to the outdoor temperature in an R22 system. However, this rule of thumb (obviously) does not work on an R-410A system. A more applicable guideline is 20°-25° suction saturation below outdoor ambient.When connecting gauges, connect to the always-suction port on the low side. On quite a few systems, you can get your head pressure on the liquid line, but some systems may require you to connect to the discharge line to check the head pressure.
