Using this dispenser is easy. First, open the hinged access door on the side. Then, insert two rolls of toilet tissue with up to a 5-1/4 inch core and 1000 single-fold or half-fold toilet seat covers. Make sure the tissue rolls are placed on the non-removable polyethylene spindle properly. Close the door and lock it with the keys provided. When you need toilet paper or a seat cover, just use the dispenser as you normally would. As for maintenance, regularly clean the stainless steel surface with a mild cleaner to keep its satin finish looking great. Check the locks and hinge periodically to ensure they work smoothly. Don't try to remove the polyethylene spindle by yourself as it's non-removable. If you have any issues, refer to the manufacturer's instructions or contact customer service.
