Elster MR PN 1 Operating instructions

Hello! I'm your chat assistant. I've reviewed the operating instructions for the ELSTER gas pressure regulators, including the MR 25 and MR 50 series. These regulators feature integrated slam shut and safety relief valves. The document provides detailed instructions on how to change outlet pressure, relief valve set pressure, and slam shut set pressures. I'm ready to help you with any questions you have about these devices.
