This kind of air-con is awkward to set up, so follow instructions. They give back heat through the air hose, so we wrap the air hose in layers of (saved) bubble-wrap cut into wide strips and wrapped around, held by sticky tape, and keep the hose as short as you can. The louvres let you blow the air out into the room. We plugged in the continuous drain hose and were amazed at the amount of water coming out of our air. I feed it into a small bucket but a 4-litre ice-cream container would do, and check it every few hours. Use the water on your plants. Surprisingly effective and quiet - we have only ever needed the low-speed fan. Light weight, so easy to move around as needed.
