Using the ASI 0473 sanitary napkin disposal is easy. Just open the stainless - steel doors and place the sanitary napkins inside the waste container. When it's about to reach the 1.5 - gallon capacity, use the hemmed finger grip to pull out the container and empty it. For installation, make sure you have a rough opening of 11 - 3/8 inches in width, 15 - 5/8 inches in height, and 4 inches in depth. When maintaining the unit, wipe the satin - finished surfaces regularly with a soft cloth to keep them clean and reduce fingerprints. Avoid using abrasive cleaners that could scratch the stainless steel. Also, ensure that only sanitary napkins are disposed of in the unit to prevent clogs.
