What is the first step in the operation of a bypass chemical feeder?

The first step in the operation of a bypass chemical feeder is to isolate and vent the feeder. This step is essential because it ensures that the feeder is safely and effectively disconnected from the system before introducing any chemicals. Isolating the feeder prevents any unintended reactions or contamination with the existing system fluid, which could be hazardous. Venting the feeder allows for the safe release of pressure or residual chemicals, ensuring that the environment is safe for the operator and reducing the risk of spills or other accidents when the feeder is actively in use.

Starting with isolation and venting also sets the stage for the subsequent steps, such as opening isolation valves and introducing the correcting chemicals. By following this procedure, steamfitters can ensure the chemicals are fed correctly and safely into the system without compromising operational integrity or safety.
