Thread: Air handler installed upside down

Trane updraft air handler installed upside down......never seen this before. Is there a problem with this installation other than no trap at condensate?

Unless they re-oriented the A coil that could be a real problem. They probably did but did they do a good enough job to keep water from hitting the electronics?
Beyond that where does that condensate drain hose terminate to, is there an air gap or trap? Are they potentially contaminating the air stream with sewer gases?

As Marcus was headed (I think) - vertically and right side up is not the same as vertically and up side down.

I may have missed it looking on my phone, but I didn't see anything permitting vertically and up side down, regardless of any changes made.

As Marcus pointed out up ... vertically and up side down puts any and all condensation above the electronics ... which I doubt is approved by the manufacturer.

Crawlspace was not entered due to 3-6" of standing water and mud inside of crawlspace of this modular home, so I do not know where the condensate terminates. If the crawl was accessible, it is it is doubtful anything would be visible as sheathing is adhered to floor framing members, all that was visible from hatch was the steel rails and sheathing.

If in the picture this is the same unit as a Trane TEM4 Air Handler its rated for Multi-Position Installation.

There is still a right side up and up side down to mult - position and convertible horizontal/vertical units.
