Minor Visio Schematic Corrections Needed

I have an existing Microsoft Visio schematic that just needs some light polishing. The job is straightforward: apply a few minor corrections I will point out, then insert clear text annotations so the diagram reads intuitively for non-technical viewers. I may also ask you to drop in a handful of simple shapes—circles, plumbing —once we see where they improve clarity, but the final mix is still open for discussion.

You’ll work directly in the .vsdx file I supply, preserve the current layout, and return the updated schematic ready for immediate use.
