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 from multiple low-flow laminar options depending on your needs. To power the faucet, you can either use the standard battery pack with 4xAA alkaline batteries or the optional AC plug-in adapter with battery backup. Keep an eye on the LED indicator in the sensor package for low battery status. When installing, make sure the centershank is secured with the rotation-resistant locking nut. The faucet is designed to integrate well with Bradley lavatories, so ensure proper alignment. For maintenance, regularly clean the spout and the sensors to keep them working effectively. Avoid using abrasive cleaners on the polished chrome finish as it may damage the surface. This faucet complies with ADA guidelines and is lead-free, so you can use it with peace of mind.
