Using this paper towel dispenser is easy. First, make sure you have the right rough opening in the wall for installation. Then, unlock the door with the key, open it, and load up to 350 C fold or 475 multi - fold paper towels into the cabinet. Close the door and lock it. When someone needs a towel, they can simply pull one out. As for maintenance, keep it clean by wiping the stainless - steel surface with a soft cloth regularly. Check the keyed tumbler lock every now and then to ensure it's working properly. If you notice any issues with the hemmed edge or the towel - pulling mechanism, stop using it and have it inspected. Always use the recommended paper towel types to avoid jams.
