NEW Polaris 65 goes only backwards

Just unboxed and installed brand new water handling mechanism in my Polaris 65 bottom frame bought from Amazon. Hooked it up to the pool and it took off backwards and piston refuses to return to the rear so it can go forward. Any hints since it came out of the box doing this?

I got tired of throwing parts at my old one, (piston, cylinder, O-rings, etc.) and just ordered an entire new mechanism and she won't go forward!
