Setrab sideways oil cooler line routing?

I think I may have switched my lines on my oil cooler and need confirmation of inlet/outlet. I believe you want the inlet hose at the bottom and outlet hose at top (oil cooler fills from bottom). I have the inlet hose going to the top and outlet hose at the bottom (oil cooler filing from top).

This is a sideways setrab core (stett stage 2)
