Using the ASI 0852 sanitary napkin disposal unit is easy. Just open the door on the top and place the feminine products inside. When it's getting full, empty it out regularly to keep it working well. For installation, find a hard surface where you want to place it. Then, use two No. 10 self - tapping screws (not included) to attach it through the keyhole slots on the back. Make sure the surface is flat and strong enough to hold the unit. To maintain it, wipe the satin finish surface with a soft cloth regularly to keep it looking shiny and to remove any fingerprints. Avoid using harsh chemicals as they might damage the stainless steel. If there are any stubborn stains, use a mild soap and water solution.
