My helper found this for me, and we ordered it on-line. In the back room where the AC unit is, we had to have the  
vent go through a long piece of wood, and was drilled through that. Separate water hose drips into the back garden.
This unit solved my problem since I have a flat roof, and cannot connect a vent from AC in the home. So far, the unit
cools the room quickly, and efficiently!
