Using this paper towel dispenser is easy. Just wave your hand in front of the sensor, and it will dispense a paper towel for you. When installing, make sure to follow the ADA standards and local installation codes. For maintenance, regularly clean the stainless - steel surface with a soft cloth and a mild cleaner to keep its satin finish looking great. If you need to refill the paper towels, unlock the door using the provided key, and replace the roll. Be careful not to force the door open as it may damage the lock. Keep the dispenser away from harsh chemicals to prevent damage to the stainless - steel material.
