After assembly, I only checked the operation once, and I haven't done any painting or the like. There are accessories such as ducts, but there is no instruction manual. In addition to the main unit, I will include a window attachment kit. I only opened the instruction manual to write down the dimensions, and I haven't opened the parts inside. The partition and fan unit will be disassembled for shipping. Feel free to ask any questions in the comments. Instant purchase is possible. Thank you.
