What is the first step in removing a regulator from service?

The first step in removing a regulator from service is to take it off automatic and set it to manual. This step is crucial because putting the regulator into manual mode allows for the safe handling and maintenance of the device. By disengaging the automatic function, you reduce the risk of unintended operations or adjustments that could occur while removing the regulator, ensuring that the system remains stable during the process of removal.

Setting the regulator to a neutral position, removing it from its mounting, or disconnecting all wires may seem like viable actions, but they should occur after ensuring that the regulator is no longer automatically controlling the system. The initial transition to manual mode is a safety protocol that precedes other steps in the removal process.
