Using this paper towel dispenser is easy. Simply open the door with the key, load the C - fold or multifold towels into the dispenser, and close the door. When the cabinet slots show that it's time to refill, just repeat the process. Remember to use only the recommended types of towels to ensure smooth dispensing. To keep it in good condition, clean the exterior regularly with a soft, damp cloth. Avoid using abrasive cleaners as they may damage the plastic surface.
