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. You can choose different low-flow laminar options according to your needs. The spout is designed to give you enough space for handwashing. For power, you can use the included 4xAA alkaline battery pack as the standard power source, or you can opt for the AC plug-in adapter with battery backup. Keep an eye on the LED indicator in the sensor package for low battery warnings. When it comes to maintenance, since the faucet has a PVD finish, it's very durable and resistant to corrosion, discoloration, and tarnishing. But it's still a good idea to clean it regularly with a soft cloth and mild cleaner. Also, make sure to follow the ADA guidelines and keep in mind the cUPC and NSF/ANSI 372 certifications when installing and using the faucet. This will ensure its proper functioning and safety.
