The Nason pressure switch trips around 115 psi, well above the rated pressure of the compressor. It should not pressurize the system to the "fully charged" 115 psi level.
I don't know whether it is allowed to adjust the Nason switch to trip at a lower psi.

If this is the old FRC compressor, it will run to 120 PSI, no problem. The pressure switch is sealed. It is somewhat adjustable, but it would no longer be First legal. Since the rules require a specific part number, you cannot order it with a lower set pressure. Lot of discussion about this last year.
