What is the proper pressure for 410a?

For R-410A, a working pressure capability of at least 400 psi is recommended (this includes recovery cylinders). Standard DOT recovery cylinders rated for 350 psi should not be used.Click to see full answer. Then, what should the high and low side pressures be?The low-side should be near 30 PSI at 90 degrees Fahrenheit or less. Pressure that is too much lower or higher shows there is a problem. On a properly working system, high-side pressure will be about twice the ambient temperature, plus 50 PSI.Additionally, what is the pressure of r410a at 72 degrees Fahrenheit?

Use hoses with a 750-psi service pressure rating. Leak detectors should be of the HFC type. R-410A is compatible with POE oils.
