hello hello
Expert:  BillyHvac replied 8 months ago.

The top of the coil should point towards blower .

air enters and is drawn through the large open end and through the coil.

If your air is entering the top part of coil it is backwards.

What about the service bulletin for flipping the coil to the correct position?
Expert:  BillyHvac replied 8 months ago.

Now this is a Horiz left flow if I see the pics right....air enters right and goes out left?

See here

And the flipping is is in the manual but you would just be doing it in reverse from the downflow configuration
