Using this dispenser is easy. First, unlock the door with the key provided. Then, open the door and fill each compartment with up to 250 toilet seat covers and two standard core tissue rolls. When it comes to the waste receptacle, simply open the door and empty it when it reaches its 0.8-gallon (3.0-liter) capacity. For maintenance, use a soft cloth to clean the satin - finished stainless - steel surface regularly. Avoid using abrasive cleaners as they can scratch the surface. Keep the key in a safe place to prevent unauthorized access. Also, check the theft - resistant spindles periodically to make sure they're working properly.
