Using your Bradley toilet paper and seat cover dispenser is easy. First, make sure you've installed it correctly following the installation instructions. To load the toilet paper, open the hinged access door on one side and place the two rolls of up to 5 - 1/4 - inch core toilet tissue onto the spindle. For the seat covers, put up to 1000 single - fold or half - fold covers in the designated area. When it comes to using the waste receptacle, just open the push flap door, and it will self - close after you're done. Remember, the spindle is made of polyethylene and can't be removed by the user. Before installation, always double - check the rough - in dimensions. You need a wall opening of 15 3/8 inches wide, 28 7/8 inches high, and 4 1/4 inches deep. Use the included mounting screws to secure it. To keep your dispenser in great shape, clean the stainless steel surfaces regularly with a mild cleaner. Avoid using abrasive materials that could scratch the satin finish. If you need to replace the napkin disposal liners, you can order a box of 500 by using part number P11 - 022.
