Using your Chris Ceiling Shower Arm is a breeze. First, choose the right length for your shower space from the available 100mm, 200mm, 300mm, or 400mm options. Then, follow the included instructions to install it on your ceiling. Make sure to tighten all connections properly to avoid leaks. When using, simply turn on the water and enjoy the great water flow. As for maintenance, regularly wipe the shower arm with a soft cloth to keep its black finish looking new. Avoid using abrasive cleaners that could damage the surface. If you notice any issues, such as reduced water flow, check for clogs and clean the arm as needed.
