Using the Brizo Kintsu SmartTouch Pull - Down Faucet is a breeze. To turn it on or off, just tap anywhere on the faucet thanks to the SmartTouch Technology. When using it, keep an eye on the LED indicator for water temperature so you don't get a surprise with scalding or cold water. If you want to expand its functions, you can add the optional A/C adapter. And if you're into smart home tech, connect the voice activation device. When using the pull - down spray head, make sure to handle it gently and return it to its place properly. For maintenance, clean the faucet regularly with a soft cloth and mild cleaner. Avoid using abrasive materials that could scratch the finish. And always follow the instructions that come with the optional accessories.
