2. Setup and Installation
Installation of the GROHE Eurosmart Shower Valve Trim requires careful attention to plumbing connections and compatibility. It is highly recommended that installation be performed by a qualified professional plumber.
Required Components (Sold Separately):
- GrohSafe Universal Pressure Balance Rough-In Valve 35110: This trim is designed for use with the GrohSafe Universal Pressure Balance Rough-In Valve 35110. Ensure you have the correct rough-in valve installed in your wall.
- GROHSAFE ADAPTOR KIT 14140000: If you are installing this 3.0 series trim with a 2.0 series GrohSafe valve, the adaptor kit (Model 14140000) is required for proper fit and function.
General Installation Steps (Consult Included Installation Guide for Details):
- Prepare the Rough-In Valve: Ensure the rough-in valve is securely installed and all plumbing connections are complete and leak-free.
- Install the Adaptor (if needed): If using a 2.0 series GrohSafe valve, install the adaptor kit 14140000 onto the rough-in valve according to its instructions.
- Mount the Trim Plate: Position the trim plate over the rough-in valve and secure it using the provided screws. The concealed mounting design ensures a clean look.
- Attach the Handle: Connect the handle to the valve stem and secure it. Test for smooth operation.
- Test for Leaks: Turn on the water supply and carefully check all connections for any leaks.

3. Operating Instructions
The GROHE Eurosmart Shower Valve Trim is designed for intuitive control of water flow and temperature.
Turning Water On/Off:
- To turn the water on, rotate the handle counter-clockwise from the 'off' position.
- To turn the water off, rotate the handle clockwise back to the 'off' position.
Adjusting Water Temperature:
- The handle controls the temperature. Rotating it towards the red indicator (typically left) increases the hot water.
- Rotating it towards the blue indicator (typically right) increases the cold water.
- This is a pressure balance valve, meaning it maintains a consistent temperature even if there are pressure fluctuations in your hot or cold water supply. It does not control water volume or flow rate independently.

4. Care and Maintenance
To maintain the pristine appearance and functionality of your GROHE Eurosmart Shower Valve Trim, follow these care instructions:
- Cleaning: Clean the chrome finish regularly with a soft cloth and a mild, non-abrasive cleaner. Avoid using harsh chemicals, abrasive sponges, or acidic cleaners, as these can damage the StarLight finish.
- Drying: After cleaning, wipe the surface dry with a soft cloth to prevent water spots and maintain shine.
- Avoid Scratches: Do not use sharp objects or tools that could scratch the surface.

5. Troubleshooting
If you encounter issues with your GROHE Eurosmart Shower Valve Trim, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inconsistent water temperature | Faulty pressure balance cartridge or issues with hot/cold water supply. | Ensure hot and cold water supplies are fully open. If the problem persists, the pressure balance cartridge may need inspection or replacement by a professional. |
| No water or low water flow | Water supply turned off, clogged showerhead, or issue with rough-in valve. | Check main water supply. Clean or replace showerhead. Inspect the rough-in valve for obstructions or issues. |
| Handle is stiff or difficult to turn | Mineral buildup or worn cartridge. | Clean around the handle base. If still stiff, the cartridge may need lubrication or replacement. |
| Leaking from the trim plate | Improperly sealed trim plate or issue with rough-in valve. | Ensure the trim plate is correctly seated and sealed. Check the rough-in valve for leaks behind the wall. Professional assistance is recommended. |
| Incorrect trim/valve compatibility | Using a 3.0 series trim with a 2.0 series valve without the required adaptor. | Verify that the correct GrohSafe Universal Pressure Balance Rough-In Valve 35110 is used, or that the GROHSAFE ADAPTOR KIT 14140000 is installed if using a 2.0 series valve. |
