regulator inlet pressure is greater than the safe working

pressure of the downstream equipment.

Regulator operation below the maximum pressure

limitations does not preclude the possibility of damage from

external sources or debris in the line. The regulator should

be inspected for damage after any overpressure condition.



The regulator is factory set at approximately the midpoint

of the spring range or the pressure requested, so an

initial adjustment may be required to give the desired

results. With proper installation completed and relief

valves properly adjusted, slowly open the upstream and

downstream shutoff valves.

To change the outlet pressure, remove the closing cap or

loosen the locknut and turn the adjusting screw clockwise

to increase outlet pressure or counterclockwise to

decrease outlet pressure. Monitor the outlet pressure with

a test gauge during the adjustment. Replace the closing

cap or tighten the locknut to maintain the desired setting.
