Using this product is a breeze. First, install it in a wall with the specified rough opening dimensions. Open the door to load either 300 C - fold or 400 multi - fold towels into the dispenser. The TowelMate technology will help you save on towel usage, so just pull out the towels as needed. When the waste container is full, simply remove it (it's leak - proof, so no mess) and empty the trash. The cable door - swing limiter keeps the door from swinging too far. As for maintenance, regularly wipe down the satin - finish stainless - steel exterior with a soft cloth to keep it looking shiny. Don't use abrasive cleaners as they might damage the finish. There's no need to worry about locking the cabinet, but make sure it's installed in a suitable location.
