Using this Bradley touchless faucet is easy. Just wave your hand near the sensors, and the water will turn on. The indicator lights on the spout will let you know if the faucet is powered, activated, or if the batteries are running low. When the low - battery light comes on, simply replace the 4xAA alkaline batteries. For installation, make sure to use the tempered line adapter for a tempered water supply. Keep the faucet clean by wiping it regularly with a soft cloth. Avoid using abrasive cleaners as they can damage the Brushed Stainless PVD finish. This finish is durable, but harsh chemicals can still cause problems. Also, as it meets ADA guidelines, ensure it is installed in a way that maintains compliance for easy access.
