Calibration
Remove the cover and locate the 1/4” hex head adjusting screw. To increase the set point,
extend the spring by turning the adjusting screw clockwise. To decrease the set point, turn
the adjusting screw counterclockwise. An independent pressure source and gage should be
used for precise setting.
Do not adjust any other screws or brackets. Movement of these parts could
render the device inoperative.
