Steam Humidifier on Return Duct?


I have installed an Aprilaire 800 steam humidifier in our 2-story house. I have a downflow furnace with one duct going upstairs and another feeding the downstairs. Currently, I have the dispersion tube installed on the supply duct that goes upstairs. Unfortunately, the upstairs windows begin to condense before there is much change in downstairs humidity. If I shut off the humidifier, the upstairs and downstairs humidity will gradually equal out over a few days.

I would like to put a 2nd dispersion tube on the downstairs supply duct, but the supply duct is too low to the garage floor to have room for a drip tee and trap.

So my next thought was too install a single dispersion tube on the return duct? Is this a bad idea? I know that warm air absorbs more moisture than cold air, but with my current set up, the humidifier runs with just the fan most of the time anyways.

Any thoughts?

Thanks!

Bad idea. The moisture will get inside the fan motor and hit the circuit board and ruin both of them.
