Repair Kits (RK) are used to upgrade -01* through -4 size regula- tors from the old, "flat" diaphragm style regulator to the new, "molded" diaphragm style regulator, as well as to repair "mold- ed" diaphragm style regulators. Note that for -5 through -7 sizes, a Repair Kit is used to repair only a "molded" diaphragm style regulator. An Upgrade Kit (UK) is required for the -5 through -7 sizes to change from a "flat" diaphragm style regulator to a "molded" diaphragm style regulator because the Upgrade Kit includes a necessary new gas diaphragm cover (see Figure 1). If style of regulator is not known, order a -UK for -5, -6, and -7 sizes to assure all required parts are supplied. For Viton regulator repair kits, use -VRK or -VUK suffix. CAUTION: The molded type diaphragm cannot directly replace an existing flat type diaphragm and gasket unless installed with a complete Upgrade Kit. Regulators will not function with this molded diaphragm if internal parts are from the flat diaphragm style regulator. Internal parts must be from an existing molded diaphragm style regulator or must be rebuilt with the components found in an Upgrade Kit for the regulator to operate properly.
DISASSEMBLY : Regulator need not be removed from pipeline to repair/upgrade. Step One A (7216 only): Remove spring cartridge cap (1) and insert a ¼"-20UNC bolt into the spring eye (2). Pull the spring eye (2) and washer (3) from the spring cartridge (4) and disconnect from the spring (5). Carefully detach the gas diaphragm cover (8) and spring (5) from the gas diaphragm case
WARNING: Gas must be turned off and locked out before servic- ing regulator or any gas component.
REPAIR and UPGRADE KIT INSTRUCTIONS Note that loose parts are not available and a repair or upgrade kit must be purchased to repair or upgrade a regulator.
