Neither of those symbols are shown in the MI that comes with the boiler on the R40 that I was looking at yesterday.
Is there a "better" version of the MIs that I could ask for with all the information in it?

WB do service booklets for the CDi range old and new, you can either download them from their website or order them from WB literature line.
I will dig out the part numbers for you when I get minute as without them you are liable to end up with a set of instructions for danesmoor 18/25. I kid you not
absoloutly useless the WB literature dept
