Installs look good, might want some more support under the drain pan, company I used to work installed some units exactly like that above a false ceiling in a bar,I even told the foreman on that job they should put plywood or something under the pan, he said it would be fine, later that summer a drainage problem developed, once the pan got full of water it buckled in the middle and dumped water all over the people sitting at the bar, OMG I wish I had been there to see that, instead Im the one that they sent there to catch hell from the bar owner....again not trying to critcize your work, just seeing that pic brought back the memory so I thought I'd share
never though about the pans buckling. We used to use plastic pans, which I did put extra under, above what co policy called for--only had one to get water and it held up with about 10 gallons in it. A few failed, so they went to the seamless drain pans we make in the shop, no solder, the edges are folded into shape.
I slope them so much, and with the fitting so low in pan, I doubt much water would be in the pan even if it stopped up(I'll test one just to see what happens, though). The drain setup is co policy, seems redundant with e-z-trap, pan switch and emergency drains run outside, above window of course.
I think the angle of picture makes it look like the rod is blocking the door. The second and first units have almost the exact same setup.
Both units have the rod 1 to 1 1/2" in from the ends, tranes' blowers are 6" down from the top of unit(vertical) so there's plenty of space to pull blower.
Some of the units though, you have to take out the bar the doors screw to to get the blower out
The angle of the photograph was causing me some confusion. I looked closer at the hanger rod and uni-strut at the bottome of that unit and saw that it is exactly as you said it is. Sorry about that, I'm blind in one eye and can't see out of the other one sometimes.
