Using your OTTI Pull - Out Sink Mixer is easy. Just turn the handles to adjust the water temperature and flow. You can pull out the spray head to reach different parts of the sink. When using, don't use excessive force on the pull - out head to avoid damage. For maintenance, clean the mixer regularly with a soft cloth and mild cleaner. Don't use abrasive cleaners as they can scratch the brushed nickel finish. Check the connections periodically to make sure there are no leaks. If you have any problems, refer to the product's specifications in the image or contact customer service.
