Using the Brizo Kintsu SmartTouch Pull - Down Kitchen Preparation Faucet is a piece of cake. To turn it on or off, just give it a gentle tap anywhere on the faucet body thanks to the SmartTouch Technology. The TempID Feature shows the water temperature through an LED light, so you can always get the right water temp for your needs. If you have model EP102157, you can install it easily without worrying about batteries using the optional A/C Adapter. And if you have model EP100854, connect it to your smart home devices for voice - controlled operation. As for maintenance, keep the faucet clean by wiping it regularly with a soft cloth. Avoid using abrasive cleaners as they might scratch the surface. When there's a clog in the spout, you can remove the aerator and clean it under running water. This will keep your faucet looking good and working great for a long time.
