Using your Oskar Tall Basin Mixer is easy. Just turn the handles to adjust the water temperature and flow. For cold water, turn the handle to the left; for hot water, turn it to the right. When not in use, make sure to turn the handles fully off to avoid leaks. To keep your mixer in good condition, clean it regularly with a soft cloth and mild soap. Avoid using abrasive cleaners as they can damage the matte black finish. Also, check the water pressure occasionally to ensure it stays within the 100 - 500kPa range. If you notice any problems, contact the customer service team for assistance.
