If factory preset, verify set point before service. To adjust: turn slotted screw clockwise to increase, counterclockwise to decrease set point. Use "T" assembly with manometer for calibration accuracy.
Select vibration-free location protected from oil/water. Position pressure connections downward with diaphragm in vertical plane. Use 1/4" O.D. metal tubing. Electrical connections via screw terminals marked "common", "norm open", and "norm closed". Do not exceed 15A resistive load rating.
