I ran across a Trane (American Std) Air Handler with Electric Heat that based on model number 2TEC3F42A1000AA, it is a Airtite Air Handler which can be put in any configuration, A/C coil with 42MBTHu cooling. It is configured in a Vertical up mode so I am guessing from what I can tell that cooling coil in bottom and fan in top. Serial number is 62213CN51W (so 2006 Model I believe)
Problem is, the enclosure is dented at bottom and it has an air filter laying down in it which would be hard to get in and out.
Looking at the C-channel rails, I am wondering if there was supposed to be a drip pan below the coils right there and wondering if the air filter is actually supposed to go in the duct above.
If the filter is supposed to go there, it seems totally the wrong size or something.
Any help would be greatly appreciated. I admit, I am a bit clueless on this one and cant find a good diagram on-line
