Yeah, I'm not too sure either but I plan on setting the thermostat on 74 so it shouldn't be too hard on the compressor. If it was air conditioned down to 65 then there might be an issue. I think I should be ok. I hope.
Play it safe and add a few humistats around the room, they're like $20 at Radio Shack; 12K should keep 74 easily but humidity may be another story with all the open tops.
