Using this napkin disposal unit is a breeze. Simply open the door, which is held in place by a magnet catch and has a cable door - swing limiter to prevent it from swinging too wide. Put your used napkins into the removable waste receptacle inside. When the receptacle is full, just take it out, empty it, and put it back. For installation, if you choose surface mounting, it's straightforward due to its compact design. If you want recessed mounting, you can remove the skirt in the field. As for maintenance, keep the unit clean by wiping it with a mild cleaner regularly. Avoid using abrasive materials that could scratch the matte black finish. Check the magnet catch and door - swing limiter occasionally to make sure they're working properly.
