Using the ASI 0030 toilet paper dispenser is easy. First, make sure to install it on a hard surface following the installation steps. Use the four self - tapping screws and take advantage of the keyhole and horizontal slots for proper positioning. When it comes to loading the toilet paper, open the locked door with the key. Place two rolls of standard toilet paper up to 5.25 inches in diameter inside. One roll will be visible for use, and the other will be stored safely behind the door. As you use the paper, the bottom roll will deplete first, and then the top roll will automatically drop into place. Remember, the rollers can't be removed without unlocking the door, so keep the key handy. For maintenance, since the dispenser has a satin finish that resists fingerprints, you can simply wipe it down with a soft cloth. If there are any stubborn stains, use a mild cleaning solution. Also, during installation, make sure to follow the ADA guidelines for proper height to ensure easy access for all users.
