Is this RODI setup correct?

Good eye, it's actually evident in your first two photos as well. The flow restrictor/flush valve is supposed to be plumbed into the yellow waste line. The white tubing from the prefilters should go directly to membrane. Looks like you'll need a longer piece for that (or flip the membrane housing into the other direction). This is where the auto shut off valve would normally be plumbed in.
