Ok guys. No reply to my question. Dont worry about it I have solved the problem.
I have found a second OMC "official" manual in my library, this one is a plastic spring type binder as opposed to the other which is a standard stiff paper back. Both show the same re circulation schematic but the binder type has the labels as to where the tubes go. SOAB. I have penned the info into the other official manual.
