The Fisher R622H first-stage regulator is designed to reduce the tank pressure for the second-stage regulator in domestic applications. Inlet and outlet gauge taps allow for easy system testing. The combination of a high capacity relief valve and large vent provide overpressure protection that exceeds UL standards. When used in conjunction with an R622 or R652, the two-stage system will limit the downstream pressure from the second-stage to 2 psig even in a double failure situation.
Fisher equipment must be installed, operated and maintained in accordance with Federal, state, and local codes and Fisher instructions. Only personnel trained in the proper procedures, codes, standards and regulations of the LP-gas industry should install and service this equipment.
