4. Installation
This section outlines the general steps for installing the handheld showerhead. For detailed instructions specific to your shower system, refer to the installation sheet provided with your product and any accompanying components (e.g., hose, wall holder).
- Preparation: Ensure the main water supply to your shower is turned off. Gather necessary tools, which typically include an adjustable wrench and plumber's tape.
- Remove Old Showerhead (if applicable): Unscrew your existing handheld showerhead from the shower hose. Clean any threads on the hose connection.
- Apply Plumber's Tape: Wrap plumber's tape (PTFE tape) clockwise around the threads of your shower hose connection. This helps create a watertight seal.
- Attach New Showerhead: Carefully screw the GROHE Tempesta Classic Handheld Showerhead onto the shower hose connection. Hand-tighten first, then use an adjustable wrench for a final quarter-turn, being careful not to overtighten.
- Check for Leaks: Turn the main water supply back on and check for any leaks around the connection point. If leaks occur, tighten slightly or reapply plumber's tape.

5. Operation
The GROHE Tempesta Classic Handheld Showerhead features four distinct spray patterns, easily selectable by rotating the spray plate.
5.1 Spray Patterns
- Rain O2: A soft, voluminous spray enriched with air for a gentle, full shower experience.
- Rain: A wide, even spray that mimics a warm summer rain, providing full body coverage.
- Jet: A focused, powerful spray ideal for rinsing shampoo or invigorating the skin.
- Massage: A pulsating spray designed to soothe and stimulate, perfect for muscle relaxation.

To change the spray pattern, simply rotate the outer ring of the showerhead's spray plate in either direction until the desired pattern is selected. Ensure a firm grip, especially with wet hands.
6. Maintenance
Regular cleaning and maintenance will preserve the finish and functionality of your GROHE Tempesta Classic Handheld Showerhead.
- Cleaning the Finish: Use only a soft cloth and a mild soap solution or a non-abrasive liquid cleaner. Avoid abrasive sponges, scouring agents, or cleaners containing alcohol, acid, or ammonia, as these can damage the StarLight chrome finish.
- Cleaning the Spray Nozzles: The showerhead features flexible silicone nozzles (SpeedClean) that resist limescale buildup. To remove any mineral deposits, simply wipe the nozzles with your finger or a soft cloth.
- Filter Screen: Periodically check the filter screen located at the connection point of the showerhead to the hose. If clogged, remove and rinse it under running water to clear debris.
7. Troubleshooting
If you encounter issues with your showerhead, refer to the table below for common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Low water pressure | Clogged spray nozzles or filter screen. | Clean the spray nozzles by wiping them. Check and clean the filter screen at the hose connection. Ensure no external flow restrictors are present in your shower system. |
| Water leaks from connection | Loose connection or insufficient plumber's tape. | Ensure the connection is tightened properly. If necessary, reapply plumber's tape to the threads and reattach. |
| Difficulty changing spray patterns | Mineral buildup or stiff mechanism. | Clean the spray plate and surrounding area to remove mineral deposits. Apply a small amount of silicone grease if the mechanism remains stiff. |
