Hi I just got my etek 4 and I took it apart to clean it, i took out the rammer housing the one that holds the LPR but i didn't look which way is up or down. So now i have the housing and it has two sides that it can go in so that the screw that holds it can keep it in. One side is just a dimple and the other side is a full hole going in. So I'm wondering if someone could tell me which way to put it in. If it helps in the manual it sais "Ensure that the outlet port is facing upwards and the valve plug is facing downwards" and then a picture but its black on black so i cant tell.
