Using the ASI 20210 Paper Towel Dispenser is easy. First, unlock the door with the provided key. Then, refill the dispenser with either 400 C-fold or 525 multi-fold paper towels. Make sure the towels are neatly placed within the internal stack guides. When you need a towel, simply pull it through the opening. Remember to keep the key in a safe place to prevent unauthorized access. To maintain the dispenser, wipe it regularly with a soft cloth to keep the stainless - steel finish looking good. Avoid using abrasive cleaners as they may damage the surface. Check the refill viewing window often to know when it's time to add more towels.
