Using the Brizo Kintsu SmartTouch Pull - Down Prep Faucet is a breeze. To turn the water on or off, just tap anywhere on the faucet body thanks to the SmartTouch Technology. For checking the water temperature, look at the LED light which gives you a quick indication. When you need to perform different kitchen tasks, pull down the sprayer for added versatility. You can also choose to use the optional A/C Adapter (Model EP102157) if you want more power options, or integrate the voice activation feature (Model EP100854) with your connected home devices. As for maintenance, clean the faucet regularly with a soft cloth and mild soap to keep its shiny appearance. Avoid using abrasive cleaners as they may damage the finish. Also, check the connections periodically to ensure there are no leaks. If you have any issues, refer to the product manual or contact the Brizo customer service.
