Three springs provide 0 to 15,51 bar (0 to location. 225 psig) reduced pressure ranges. Clean out all pipelines before installation of the regulator Type 1305D: same as 1305C, with larger spring and check to be sure the regulator has not been damaged case and one heavy spring for reduced pressure or has collected foreign material during shipping. For NPT range of 13,79 to 34,47 bar (200 to 500 psig). bodies, apply pipe compound to the male pipe threads.

Install the regulator in any position desired, unless otherwise specified, but be sure Outlet: DN 6 (1/4-inch) NPT flow through the body is in the direction indicated by the (1) Maximum Emergency Outlet (casing) Pressure arrow on the body. Type 1305C: 17,25 bar (250 psig) Type 1305D: 37,92 bar (550 psig) Note (1) Outlet Pressure Ranges It is important that the regulator be installed so that the vent hole in the spring case is unobstructed at all Type 1305C: 0 to 5,17 bar (0 to 75 psig), 0 to 10,34 bar times. For outdoor installations, the regulator should (0 to 150 psig), and 0 to 15,51 bar (0 to 225 psig) be located away from vehicular traffic and positioned Type 1305D: 13,79 to 34,47 bar (200 to 500 psig) so that water, ice, and other foreign materials cannot (1) enter the spring case through the vent. Avoid placing Maximum Allowable Inlet Pressures the regulator beneath eaves or downspouts, and be 275,8 bar (4000 psig) sure it is above the probable snow level. Proof Test Pressure All Pressure Retaining Components have been proof Overpressure Protection tested per Directive 97/23/EC - Annex 1, Section 7.4 The recommended pressure limitations are stamped on (1) Temperature Capabilities the regulator nameplate. Some type of overpressure -29 to 93°C (-20 to 200°F) protection is needed if the actual inlet pressure exceeds the maximum operating outlet pressure rating. Overpressure protection should also be provided if the regulator inlet Installation 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 Only qualified personnel should install or service sources or debris in the line. The regulator should be inspected a regulator. Regulators should be installed, for damage after any overpressure condition. 1. The pressure/temperature limits in this installation guide and any applicable standard or code limitation should not be exceeded. www.FISHERregulators.com D100342XENG 1305 Series Startup Taking Out of Service (Shutdown) 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 To avoid personal injury resulting from sudden adjusted, slowly open the upstream and downstream shutoff release of pressure, isolate the regulator from all valves. pressure before attempting disassembly. Adjustment 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 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.
