The range hood came packaged in a heavy duty car board box. The hood and accessories were packed firmly with card board dividers. The stainless steel hood and chimney still had the protective paper on them. The instructions are not for the typical DIY person. If your not accustom to professionally installing equipment (kitchen or other) I recommend calling a professional installer. The unit shouldn't take more than 4 hours, including cutting the sheetrock, installing solid wood blocking, replacing the sheetrock etc.. I exhausted my unit through the exterior wall just above the hood and under the double 2x4 top plate framing. You may have to remove the unit several times for other work. Painting, tile work etc. Just remember to install the oversized washers under the two mounting screws. You cant initially install the unit with them. Also my wiring was already in the basic location, just had to relocate outlet behind the chimney cover. The most difficult part of the installation was reinstalling the connector boot back onto the flexible duct tube after cutting to length. I ran it under hot water with a little dish washing detergent and screwed right on . Great unit, would recommend .
