You've def got the dryer installed in the right direction. This is a dual evap coil unit. That's the reason for the "3 way valve". To split / control refrigerant flow to both coils. Hopefully the 3 way valve was in the right position when you evacuated it. Double check the amount of charge on the box label. I tried to attach the service manual but its too big. Perhaps someone can instruct me on the best way to do it, if you want it.
