the Johnson Controls P32AF-2 can detect vacuum by connecting the vacuum source to the low-pressure port while leaving the high-pressure port open to atmospheric pressure

ensuring safety and durability in R-410A and other high-pressure applications

This is a deliberate safety feature that requires a physical reset after a trip to ensure the cause of the overheat is addressed by a professional

Avoid mounting with the sample line connections facing upward
