Using your 1P Black Mica Shower Mixer with Diverter is easy. To switch between shower and bath modes, simply use the diverter. Turn the mixer handles to adjust the water temperature and flow. Make sure to keep the water pressure within a normal range to avoid any damage. For maintenance, wipe the mixer regularly with a soft, damp cloth to keep it looking clean. Avoid using harsh chemicals as they can damage the mica finish. If you notice any leaks, check the connections and contact customer service if needed.
