Wire the pressure switch to the battery and a good chassis ground, use #14 AWG WIRE MINIMUM . The compressor is calibrated to cut-in at 75 PSI and cut-out at 95 PSI . For higher cut-in and cut-out, turn the range nut clockwise . To lower cut-in turn range nut counterclockwise . [. . . ] are warranted to be free of defects of material or workmanship.
