Using this faucet is easy. Just wave your hand in front of the touch - free dual sensors to activate the water flow. When the indicator light in the spout shows low battery, simply replace the 4xAA alkaline batteries. The faucet is designed to be low - maintenance, but it's a good idea to wipe it down regularly with a soft, damp cloth to keep the Brushed Stainless PVD finish looking great. Avoid using abrasive cleaners as they can damage the finish. Also, make sure the water supply is within the appropriate temperature range for the tempered line adapter. If you have any questions, don't hesitate to contact our customer service.
