Using this soap dispenser is easy. First, make sure you've installed 3 C - cell alkaline batteries in the plastic battery box. Then, fill the reusable plastic reservoir with your preferred liquid soap or gel. When your hand gets within 2 - 3 inches of the dispenser, it will automatically release the soap. As for maintenance, regularly clean the stainless steel surface with a soft cloth to keep its shine. Check the battery level frequently, and replace the batteries when the dispenser's performance slows down. Always follow the ADA standards and local installation codes during setup.
