Using these ASI bathroom accessories is easy. For the paper towel dispenser, simply load the C - fold or multi - fold paper towels into the unit. There's no need to adjust anything or use adapters. When you need a towel, just pull it out gently. For the toilet tissue dispenser, open the cabinet using the tumbler lock, place the toilet paper roll inside, and close it back up. You can see through the viewing slot to know when it's time to refill. With the soap dispenser, you can refill the soap through the hinged filler - top. Make sure to keep the refill window clean to avoid any blockages. When it comes to maintenance, wipe down the accessories regularly with a soft, damp cloth. Avoid using abrasive cleaners as they can damage the matte black finish. Keep the locks lubricated to ensure smooth operation. If you notice any issues, contact ASI's customer service for assistance.
