Ed, according to the Friedrich manual that came with my in-wall AC,
they are very specific that the unit should be mounted with a
half-bubble lean toward the outside to prevent overfilling of the pan,
and still have slinging action. They specifically say that mounting it
level can result in water leaking back into the house.


I don't think a half bubble will make a difference on any brand, but that is
hardly visible.
