Using your new shower set is easy. First, install all the parts following the included installation accessories. Connect the top shower head to the water inlet, and attach the handheld spray to the shower rail. To switch between the top shower head and the handheld spray, use the diverter. When using, turn on the water and adjust the temperature and flow as you like. For maintenance, regularly wipe the shower head and handheld spray with a soft cloth to keep the matte black finish looking good. Avoid using abrasive cleaners as they may damage the surface. If you notice any water leakage or other issues, refer to the warranty information for assistance.
