Using this faucet is easy. Just wave your hand in front of the sensors for touch-free activation. The indicator lights on the spout will let you know if it's powered, activated, or if the battery is low. When the battery is low, simply replace the 4xAA alkaline batteries. To maintain the faucet, wipe it regularly with a soft, damp cloth to keep the Brushed Nickel finish looking great. Avoid using abrasive cleaners as they can damage the PVD finish. Also, make sure the water supply is properly connected through the tempered line adapter. This faucet complies with ADA guidelines and is lead-free, so you can use it with confidence.
