Good luck with this. I may have gotten a bad one - the hole to drain the tank is up at the top of the tank. I was not able to fit an aquarium hose into the hole. It was small enough, but it seemed to be blocked, so the hose would not go into the tank. I had to return mine. I ran it for about 10 minutes. The vent hose got very hot - 119 degrees f. It was a very flimsy connection. When I brought it out to my car to return it, water was spilling out of the hole. I have no idea how that much water accumulated in 10 minutes. I bought model NS-AC10PWWH9 and it claimed it was discontinued, I got it for 249.00. I had faith in the Insignia brand, and the reviews were good, but this was a total waste of time and effort for me. At least I was able to get my money back.
