Using the ASI 0210 Paper Towel Dispenser is simple. First, unlock the door with the key and open it. Place either 400 C fold or 525 multi - fold paper towels inside, making sure they are aligned with the internal stack guides. Close the door and lock it. To get a towel, just pull gently from the opening. When the towels are running low, you can easily see through the viewing window and refill them. For maintenance, wipe the stainless - steel surface regularly with a soft cloth to keep it looking clean. Avoid using abrasive cleaners as they may scratch the finish. Also, check the tumbler lock occasionally to ensure it's working properly and replace the key if it gets lost.
