Using this Bradley combination unit is a breeze. To load paper towels, simply unlock the door with the provided keys and place either multi - fold or C - fold paper towels inside. Then close the door and lock it. When you need a towel, just pull it from the dispenser. For the waste receptacle, open the door and toss your waste in. When it's full, empty it into a trash bag. As for maintenance, regularly wipe the unit with a soft, damp cloth to keep the satin finish looking good. Avoid using abrasive cleaners as they can scratch the stainless steel. Check the locks and hinges periodically to make sure they're working properly. If you notice any issues, contact the manufacturer for support.
