Using this waste bin is easy. Just open the door (it's held by a magnet catch) and toss your waste inside. The removable waste bin makes emptying a breeze - simply take it out, empty it, and put it back. When installing, make sure the wall opening matches the specified dimensions: 6-3/8' W x 12-3/8' H x 3-3/4' min depth. As for maintenance, regularly wipe the satin-finish stainless steel surface with a mild cleaner to keep it looking new. Avoid using abrasive materials that could scratch the surface. And always check the cable door-swing limiter to ensure it's working properly.
