Using your Bradley Zen Series touchless sensor faucet is a breeze. Just place your hands under the spout, and the dual sensors will detect them and turn on the water. To save water, take advantage of the multiple low-flow laminar options. You can power the faucet with the included battery pack of 4xAA alkaline batteries. If you prefer, you can use the optional AC plug-in adapter with battery backup. Keep an eye on the low battery LED indicator in the sensor package and replace the batteries when needed. The indicator lights in the faucet spout will show you the power status, activation, and low battery. When it comes to maintenance, use a soft cloth to clean the polished chrome finish regularly. Avoid using abrasive cleaners as they can damage the surface. Since it's vandal-resistant, it's built to last, but still handle it with care. And remember, it's a non-returnable item, so make sure it meets your needs before purchasing.
