Using the ASI 0852 sanitary napkin disposal unit is easy. Just open the sloped door, place the sanitary napkin inside, and close the door. When it comes to installation, find a hard surface in your restroom, line up the keyhole slots on the back of the unit with the spots where you want to mount it, and use two No. 10 self - tapping screws (not included) to secure it. Remember, don't overfill the unit. It has a 1.2 - gallon (4.5 L) capacity, so empty it regularly to avoid overflow. For maintenance, clean the unit with a mild soap and water solution. The stainless - steel construction is durable, but avoiding harsh chemicals will help keep the satin finish looking great and prevent damage to the unit.
