Trane does not provide documentation on corner weights for this product.
The unit is balanced by the coil/ fan/ motor locations.
The weight would be slightly off by the motor location of either RH or LH but not enough that would lead to major weight offsets.
You can get the total weights based on the motor size, coil type and total unit weight then divide by 4.
Unit, Coil and Motor weights are located in the catalog under General Data.
