Using your ASI 20031 toilet paper dispenser is easy. First, open the door with the provided key. Place two rolls of toilet paper inside, with one on top and ready for use. Close the door and lock it to prevent theft. When the top roll runs out, the next one will be there for quick access. For installation, use the flange that comes with the cabinet and fit it into the rough opening of the right size as mentioned. When it comes to maintenance, regularly wipe the dispenser with a soft, dry cloth to keep the satin finish looking good. Check the hinges and lock from time to time to make sure they are working properly. Avoid using abrasive cleaners as they might damage the stainless - steel surface.
