Using this Bradley soap dispenser is easy. First, open the plastic battery box and insert 3 C - cell alkaline batteries. Then, fill the reusable plastic reservoir with your preferred liquid soap or hand sanitizer. Once it's installed on the wall, just place your hand within 2 - 3 inches of the dispenser, and it will automatically release the soap. When it comes to maintenance, keep the sensor clean to ensure proper operation. If the dispenser seems slow or stops working, check the batteries and replace them if needed. Also, make sure to follow the local installation codes as it complies with ADA standards. Avoid using abrasive cleaners on the stainless steel tank body to maintain its architectural satin finish.
