Use a 1 inch 25 4 mm hex rod or flat screwdriver to turn the adjusting screw key 35 either clockwise to increase outlet pressure or counterclockwise to de crease outlet pressure Shutdown First close the nearest upstream shutoff valve and then close the nearest downstream shutoff valve to vent the regulator properly Next open the vent valve between the regulator and the downstream shutoff valve nearest to it All pressure between these shutoff valves is released through the open vent valve since a Y690A Series remains open in response to the decreasing downstream pressure For a regulator with a control line the valve in the control line must also be closed and the diaphragm casing vented to the atmosphere Maintenance Regulator parts are subject to normal wear and must be inspected and replaced as necessary The frequency of inspection and replacement of parts depends upon the severity of service conditions or the requirements of local state and federal regulations Due to the care Fisher takes in meeting all manufacturing requirements heat treating dimensional tolerances etc use only replacement parts manufactured or furnished by Fisher To avoid personal injury property damage or equipment damage caused by sudden release of pressure or explo sion of accumulated gas do not attempt any maintenance or disassembly without first isolating the regulator from system pressure and relieving all internal pressure fro
