Using your new shower set is easy. First, install all the parts according to the included installation accessories. The flexible wall elbow allows you to adjust it to your needs. The top shower head gives a wide - spread water flow, and you can switch to the 3 - mode handheld spray for more targeted cleaning. When using, make sure the water pressure is within a normal range to avoid damage. For maintenance, regularly wipe the shower head and rail with a soft cloth to keep the matte black finish looking good. Don't use abrasive cleaners as they may scratch the surface. If you encounter any problems, our 15 - year warranty and 1 - year labor warranty have you covered.
