3. Setup and Installation
Installation of the GROHE GrohTherm valve trim requires careful attention to detail. It is recommended that installation be performed by a qualified professional. Ensure the rough-in valve (GROHE Rapido SmartBox 35 601 000, sold separately) is correctly installed and secured within the wall before proceeding with the trim installation.
Installation Steps:
- Install the Backplate: Secure the backplate to the wall using the provided brass screws. Ensure it is flush and properly aligned.
- Install Limit Rings: Place the temperature limit ring onto the lower cartridge, aligning the cutout with the tab. Push it straight back until seated. For the upper handle, install the limit ring with two tabs to restrict rotation. An optional Aquadimmer Stop Ring (14 060 000, sold separately) can be used for shared functionality, allowing the handle to turn further.
- Install Escutcheon Plate: Carefully push the chrome escutcheon plate onto the backplate, ensuring it snaps securely into place.
- Install Thermostatic Handle: Push the lower thermostatic handle onto its spindle, sliding it all the way back. Secure it with the snap ring.
- Install Volume/On/Off Handle: Slide the upper handle onto its spindle and secure it with its snap ring.
- Connect Sleeves: Attach the appropriate sleeves to connect the handles to their respective cartridges. For single function, ensure the adapter line is at the 12 o'clock position.
- Install Decorative Caps: Place the decorative caps onto the handles.

4. Operating Instructions
The GROHE GrohTherm valve trim offers intuitive control over your shower experience:
- Volume and On/Off Control: The upper handle controls the water flow. Turn it to the left or right to adjust the volume, and push/pull to turn the water on or off.
- Temperature Control: The lower handle allows you to set your desired water temperature. The integrated GROHE TurboStat technology ensures that the water reaches and maintains your selected temperature quickly and consistently.

6. Troubleshooting
If you encounter issues with your GROHE GrohTherm valve trim, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inconsistent water temperature | Thermostatic cartridge issue, fluctuating water pressure. | Check water supply pressure. If issues persist, the thermostatic cartridge may need cleaning or replacement. Consult a professional. |
| Low water flow | Debris in the cartridge, clogged showerhead/handshower. | Clean or replace the showerhead/handshower. If the problem continues, the valve cartridge might be obstructed. |
| Handles are stiff or difficult to turn | Mineral buildup, worn O-rings. | Clean around the handle bases. If necessary, remove handles and lubricate O-rings or replace worn components. |
| Water leaks from around the trim plate | Improperly sealed escutcheon, damaged O-rings. | Ensure the escutcheon plate is properly seated. Check for damaged seals or O-rings behind the trim. |
For complex issues or if troubleshooting steps do not resolve the problem, it is recommended to contact a certified plumber or GROHE customer support.
