Using your Bradley touchless sensor faucet is a breeze. Just wave your hand near the sensor, and the water will turn on automatically. The dual sensors ensure quick and reliable activation. For the water supply, make sure to connect it to a tempered water source using the provided tempered line adapter. When it comes to power, the faucet uses a battery pack with 4xAA alkaline batteries. Keep an eye on the indicator lights on the spout. If the low - battery light comes on, replace the batteries promptly. To maintain your faucet, clean it regularly with a mild soap and a soft cloth. Avoid using abrasive cleaners as they can damage the Brushed Bronze PVD finish. Since it's a non - returnable item, handle it with care. Also, note that this faucet complies with ADA guidelines and is lead - free, so you can use it with peace of mind.
