The internal pressure relief valve is located between the high and low side of the compressor. It is designed to open when the discharge-to-suction pressure differential exceeds 550 to 625 psid (38-43 bar). When the valve opens, hot discharge gas is routed back into the area of the motor protector to cause a trip.

A R-410A evaporator running below 100 psig will freeze-up just like its R-22 cousin. One of the most common causes of low suction pressure is loss of critical refrigerant charge caused by small leaks over time.
