Using your Bradley Zen Series touchless sensor faucet is easy. Just place your hands under the spout, and the dual sensors will activate the water flow. To save energy, use the battery power option. If you prefer continuous power, connect the optional AC plug-in adapter. Keep in mind that this is a non-returnable item. When it comes to maintenance, regularly check the battery level using the LED indicator. Replace the 4xAA alkaline batteries when the low battery light comes on. Clean the faucet with a soft cloth and mild detergent to maintain its polished chrome finish. Avoid using abrasive cleaners as they can damage the surface. The faucet is designed to be vandal-resistant, but still handle it with care. It complies with ADA guidelines, ensuring easy and accessible use for all users.
