Using the ASI 1003 waste receptacle is easy. Just press down on the access door to open it and drop your trash inside. The waste container beneath the countertop will catch the trash. When the container is full, simply remove it for emptying. As for installation, make sure the countertop thickness is between 1/2 inch and 4 inches and the rough opening measures 8 - 3/4 inches by 12 - 1/2 inches. For maintenance, regularly clean the access door and the waste container. Since they are made of stainless steel, a simple wipe - down with a mild cleaner will keep them in good condition and looking great. Avoid using harsh chemicals as they might damage the stainless steel finish.
