Using your Mica 3 - Way Filter Sink Mixer is easy. First, connect it to your water supply and make sure it's properly attached. If you're using a 1/4 inch hose filter kit, it will work perfectly with this mixer. Turn the taps to get water flowing. The 3 - way filtering system will start purifying the water for you. When it comes to maintenance, keep the mixer clean by wiping it with a soft cloth regularly. Avoid using abrasive cleaners as they can damage the chrome finish. Also, check the connections from time to time to ensure there are no leaks. Remember, the filter is not included, so you'll need to purchase and install it separately. If you have any issues, refer to the warranty guide for assistance.
