Using this product is easy. First, install it in the rough wall opening with the specified dimensions. Then, load your preferred type of paper towels - whether it's C-fold, multi-fold, or single-fold. When the waste container gets full, simply remove it, empty the waste, and put it back. Keep in mind that the door is designed to conceal the flange, so make sure it's properly closed after each use. For maintenance, regularly wipe the satin-finish stainless steel body with a soft cloth to keep it looking new. Avoid using abrasive cleaners that could scratch the surface.
