Ducting dehumidifier question

I am considering buying a AprilAire Model 1850W (manual PDF).

It would be located in an unfinished room, with ducts going through the wall into the finished area.

There would be a high vent and a low vent. The high one would be about 1 ft from the ceiling. The low one would be about 1 ft from the floor.

Which vent (high or low) should be the input, and which should be the output? Thanks

Good question.
The cooler damper air will stay near the floor so I'd draw from low and discharge high.

In addition to temperature changing the weight of air, humid air is lighter than dry air at the same temperature. If your floor is concrete I think that would dominate the temperature issue. If the floor is wood over some insulation then it may have a very similar temp as the air.

I suspect the output of the dehumidifier will be reheated after it has passed over the cold coils and I would want that at floor level. If the output is still cool air, then duct it high.

BTW, just guessing with what little I know.
