Help With Pump Question - Berkeley SSHM-2

Hello - I have a Berkely SSHM-2 that I have been using for lawn irrigation for about 10 years.
I usually pull it for the winter and store in my garage but I forgot and tonight we will have a hard freeze (18F) so I drained the lines, but then to drain pump I mistakenly unscrewed the Re-circulation Valve instead of the drain plug.
In hindsight - everything in the manual says "DO NOT REMOVE" and no other information as to why this is such a no-no to do. I drained the unit but I don't see any information as to how to reassemble/install the valve and or any particularities about it when reassembling. (It looks like it will screw back in).
I have totally disassembled and performed an impeller rebuild in August so I am familiar with the pump side.
Questions:
Anyone know why the documentation says DO NOT REMOVE and is there any concern?
Is worst case scenario I will need to pull the pump body to access both sides of the casting to reinstall the valve?
Thanks for any help. FF

I see the warnings. If you pulled the entire assembly out as one piece it should just screw right back in. The picture shows all the parts that come in the recirculation valve kit. It looks like all the parts stay contained in the cap.

Maybe it's adjustable ? Doesn't really look like it. Looks more like a purge valve.
Almost like a tire valve..... but larger.

PJ - Thanks for taking a look. In your screenshot from top left the first 3 items and the fat o-ring is what came out when i unscrewed it. (Was too cold and dark to examine further tonight). In looking at the assembly details the lower left brass piece must thread into the casting through the bore but it looks like the only way to tighten it is from the internal side (unless it has a slot on the face we cant see). Maybe that is why the warnings. As tight as the black plug was to unthread im hoping the brass threaded piece stayed torqued in place.
Possibly the warnings are due to preset adjustment you mention and if the black plug is screwed in too far it over compresses the spring and the valve wont open and it blows seals. Strike that as it has to be tightened to compress the o-ring to the flange face to seal.
I guess I'll find out when it warms up.
