Using this product is easy. First, install it on a suitable surface as it's surface-mounted. Open the door using the tumbler locks to load either multi-fold or C-fold paper towels into the dispenser. When you need a towel, just pull one out. For the waste receptacle, lift the hinged cover and throw your trash inside. As for maintenance, clean the stainless - steel surfaces regularly with a mild cleaner to keep the satin finish looking great. Check the locks and hinges periodically to make sure they're working properly. If you encounter any issues, don't hesitate to contact customer service.
