Setup and Installation
Refer to the included Installation Guide for detailed instructions. General steps for installation are provided below:
- Prepare the Area: Turn off the main water supply to your shower. Remove your existing shower head by unscrewing it counter-clockwise. Clean any residue from the shower arm threads.
- Apply Plumber's Tape: Wrap plumber's tape (PTFE tape) clockwise around the threads of your shower arm 3-4 times. This helps create a watertight seal.
- Install the Shower Head: Carefully screw the GROHE Tempesta 250 Rain Shower Head onto the shower arm by hand, turning clockwise until it is snug. Do not overtighten.
- Adjust and Test: Turn the water supply back on and check for leaks. Adjust the angle of the shower head to your preferred position.

Maintenance
To ensure the longevity and optimal performance of your GROHE Tempesta 250 Rain Shower Head, regular maintenance is recommended:
- Cleaning the Finish: The GROHE StarLight chrome finish is designed for easy cleaning. Simply wipe the surface with a soft, damp cloth and then dry it to maintain its luster. Avoid abrasive cleaners, scouring pads, or harsh chemicals, as these can damage the finish.
- Speed Clean Nozzles: The flexible silicone nozzles are equipped with the Speed Clean anti-lime system. To remove limescale buildup, simply wipe the nozzles with your fingertips. This will dislodge any mineral deposits and restore the full spray pattern.

Troubleshooting
If you encounter any issues with your GROHE Tempesta 250 Rain Shower Head, consider the following common solutions:
- Low Water Pressure: If the water flow seems weaker than expected, first check if the main water supply valve is fully open. Then, inspect the shower head nozzles for limescale buildup. Use the Speed Clean feature by wiping the nozzles with your fingers to clear any blockages.
- Uneven Spray Pattern: An uneven spray is typically caused by clogged nozzles. Perform the Speed Clean procedure as described in the Maintenance section to clear any blockages.
- Leaks at Connection: If water is leaking from where the shower head connects to the shower arm, ensure the connection is hand-tight. If the leak persists, turn off the water, unscrew the shower head, reapply plumber's tape to the shower arm threads, and reattach the shower head.
If these steps do not resolve the issue, please contact GROHE customer support for further assistance.
