Package Contents
Please verify that all components are present before beginning installation:
- GROHE Essence 3-Way Diverter Trim (Lever Handle, Escutcheon)

- Installation Guide (this document or similar)
Note: This trim kit requires a GROHE rough-in diverter valve (models 29902 or 29903), which is sold separately and is essential for operation.
Setup (Installation)
This section outlines the general steps for installing the diverter trim kit. Refer to the rough-in valve's specific instructions for its installation.
- Prepare the Rough-In Valve: Ensure the GROHE rough-in diverter valve (29902 or 29903) is correctly installed and secured within the wall according to its own instructions.
- Install the Escutcheon: Place the escutcheon (cover plate) over the rough-in valve, aligning it with the mounting holes. Secure it using the provided screws.
- Attach the Lever Handle: Connect the lever handle to the diverter mechanism. Ensure it engages properly and allows for smooth rotation.
- Test for Leaks: Once installation is complete, slowly turn on the main water supply and check all connections for any signs of leakage.

The installation process is designed to be straightforward, allowing for easy setup over the compatible rough-in valve.
Operating Instructions
The GROHE Essence 3-Way Diverter allows you to easily switch water flow between up to three different outlets (e.g., shower head, hand shower, or bath spout), depending on your rough-in valve configuration.
- Turn on Water: Ensure your main water supply to the shower is active.
- Select Outlet: Rotate the metal lever handle to select the desired water outlet. The icons on the escutcheon indicate the active outlet. For example, one icon may represent a standard shower head, another a hand shower, and a third position (if applicable) for a different function.
- Adjust Temperature/Flow: Use your separate shower mixer or thermostatic valve to control water temperature and flow rate. The diverter only controls the direction of water flow, not its temperature or pressure.

Maintenance
To ensure the longevity and pristine appearance of your GROHE Essence diverter, follow these simple maintenance guidelines:
- Cleaning: The GROHE Starlight finish is designed for easy cleaning. Use only a soft cloth and mild soap and water. Wipe the surface gently to remove water spots and residue.
- Avoid Harsh Cleaners: Do not use abrasive sponges, scouring pads, or cleaners containing alcohol, ammonia, bleach, or other harsh chemicals. These can damage the finish and void your warranty.
- Regular Inspection: Periodically check the diverter for any signs of wear or loose components. Tighten screws if necessary, but do not overtighten.
Troubleshooting
If you encounter issues with your GROHE 3-Way Diverter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Water not diverting correctly | Internal diverter cartridge issue or debris. | Ensure the handle is fully engaged in the desired position. If the problem persists, the rough-in valve's diverter cartridge may need inspection or replacement by a professional. |
| Leaks around the escutcheon | Loose mounting screws or improper sealing. | Check and tighten mounting screws. Ensure proper sealant (if applicable) was used during installation. |
| Stiff handle operation | Mineral buildup or internal friction. | Clean the exterior thoroughly. If the stiffness is internal, the rough-in valve's cartridge may require servicing. |
If these steps do not resolve the issue, please contact GROHE customer support or a qualified plumber.
