Hello, Buster! Please review pages 6 and 16 in the Owner's Manual for installation and drainage instructions. Unfortunately, you are unable to control the brightness on the panel. Please reconnect if additional assistance is needed. https://images.thdstatic.com/catalog/pdfImages/9f/9f05a919-d855-48ba-9f9f-9d66f00eb5eb.pdf -Bianca
Well, the fan is always on; the compressor only kicks on when it needs to. You can control the fan speed.
Hi, Tralach! No, water does not discharge through the vent. If the unit is properly installed through the window, there should be no exterior wall damages. ~Corletta
