Using this dispenser is a breeze. First, unlock the door with the key provided and swing it open. Then, fill each compartment with 250 toilet seat covers and two standard core tissue rolls. When it comes to the waste receptacle, empty it when it reaches the 0.8 - gallon (3.0 - liter) capacity. As for maintenance, use a mild cleaner to wipe the satin - finished stainless - steel surfaces regularly. This will keep it looking great and functioning well. Also, make sure to keep the key in a safe place to prevent unauthorized access. And don't forget to check the theft - resistant spindles from time to time to ensure they're working properly.
