Ro question

[aquaman05]

I have a ro system that is a 3 stage. The manifold has the plumbing inside.
I added a permeate pump and a extra carbon filer after the pump
I want to add a di filter and run a line to my top off water tank. I purchased the auto shutoff kit which includes a check valve, auto shutoff valve.
I'm kinda confused on plumbing this in since
The only lines I have is the ones going to the carbon filter and di filter. It shows the asv going before the membrane.
Does anyone else have a setup like this or can help with plumbing it properly?

Thanks for helping
