heres a quick question, what way up should the AFM be mounted? should the sweeper bit be on top or should it be underneath if you get what i,m saying, mine sits ontop but ive seen others that are mounted the other way up, does it make a difference to its operation?
I await replies with interest.

If it's a 6 pot then with the black cover upwards ... otherwise the mounting bolts won't line up.

And this should be posted in tech help not "Chat".
