Setting Instructions:
1. Determine desired outlet pressure for known inlet pressure.
2. Remove the tamper-resistant screw and slide the plastic cover up to access the adjusting nut.
3. Use a ⅜" diameter rod in any one of the 6 holes in the adjusting nut and rotate counter
clockwise to increase the pressure at the outlet.
4. Check valve under pressure under static and under the anticipated flowing conditions to
ascertain that the setting produces the expected results.
