Was at this book store today, it should be on wall of pride because someone put a "10" sticker on the ceiling track, so air handler 10 is easy to find, plus you can walk around the store and find all the other air handlers easily.
What I don't understand is why someone else wrote "10" with a sharpie, drew an arrow, and drew an "X" with an orange paint marker. Its easy to tell from the return, where the air handler sits in the ceiling.
Also, its hard to see in the picture but someone wrote "BELT -->" to indicate rotation, why couldn't they just write that on the side of the air handler?
