Using your Bradley touchless sensor faucet is easy. Just wave your hand in front of the sensor, and the water will turn on. To turn it off, simply remove your hand. This faucet offers multiple low flow laminar options, so you can choose the flow that suits your needs. For power, it comes with a standard battery pack of 4xAA alkaline batteries. You also have the option to use an AC plug - in adapter with battery backup. When the low battery LED indicator in the sensor package lights up, it's time to replace the batteries. The spout reach is designed to give you enough space for handwashing, so make sure to use this space effectively. Keep the faucet clean by wiping it regularly with a soft, damp cloth. Avoid using abrasive cleaners as they may damage the Brushed Brass PVD finish. Since it's a non - returnable item, handle it with care. Also, remember that this faucet complies with ADA guidelines and is certified as lead - free, so you can use it with confidence.
