Will see if I can help you out, shouldn't be too much of an issue to set up 
Edit - Your gonna have to work out which fitting is the “in” and which fitting is the “out” to each chamber, to make sense of it. Currently looks like two of the “outs” are connected together, which ain’t right, in my mind.
A pic of mine will confuse you even further. Are the outlets marked “in” and “out”?Can someone post a pic of there's so I can copy it please
