Using your new basin mixer is easy. Just turn the pin handle to adjust the water flow and temperature. For hot water, turn the handle clockwise, and for cold, turn it counter - clockwise. When installing, make sure to connect the water hoses tightly to avoid any leaks. Keep in mind that this mixer is designed for bathroom use only. To maintain its appearance, clean it regularly with a soft cloth and mild soap. Avoid using abrasive cleaners as they can scratch the brushed nickel finish. If you notice any problems, refer to the warranty information. The 15 - year warranty covers the product, and the 2 - year labor warranty means you're covered for installation - related issues.
