Using this Bobrick waste bin is easy. Simply open the door with the provided key, dispose of your waste through the opening, and the self - closing panel will cover it up. When it's time to empty the bin, unlock the door and remove the waste. For installation, make sure to cut a rough wall opening as specified in the product description. If you choose the recessed mounting option, remove the skirt first. As for maintenance, clean the stainless steel surface regularly with a mild cleaner to keep its satin finish looking great. Avoid using abrasive materials that could scratch the surface. Also, check the tumbler lock and hinges periodically to ensure they are working properly.
