Setup and Installation
Proper installation is crucial for the optimal performance and longevity of your hansgrohe shower valve trim. It is highly recommended that this product be installed by a licensed plumber to ensure compliance with local codes and proper functionality.
Required Component: This product requires the iBox Universal Plus Rough (Part No. 01850181) for installation. This rough-in valve is sold separately and must be installed within the wall before the trim can be mounted.

Ensure that the iBox is correctly positioned and secured according to its own installation instructions before proceeding with the trim installation. The trim plate, handles, and function block are then mounted onto the pre-installed iBox.

Operating Instructions
The hansgrohe Ecostat S Modern Thermostatic Shower Valve Trim features two handles for precise control over your showering experience.
- Temperature Control: One handle is dedicated to temperature adjustment. Rotate this handle to achieve your desired water temperature. The integrated thermostatic cartridge maintains a consistent temperature, even with fluctuations in water pressure. For safety, a SafetyStop button must be pressed to allow the temperature to exceed a certain limit, preventing accidental scalding.
- Volume Control: The second handle controls the water volume. Rotate this handle to increase or decrease the flow of water to your shower outlet (either shower head or handheld shower).
Familiarize yourself with the operation of both handles to customize your shower settings effectively.
Maintenance
To maintain the appearance and functionality of your hansgrohe Ecostat S shower trim, follow these general cleaning guidelines:
- Clean the surface regularly with a soft cloth and a mild, non-abrasive cleaner.
- Avoid using cleaners containing alcohol, ammonia, bleach, or abrasive agents, as these can damage the brushed black chrome finish.
- Rinse thoroughly with clean water after cleaning and dry with a soft cloth to prevent water spots.
- For internal components, periodic inspection by a qualified plumber is recommended to ensure optimal performance and address any potential issues.
Troubleshooting
If you encounter issues with your hansgrohe Ecostat S shower trim, consider the following general troubleshooting steps:
- No Water Flow or Low Pressure: Check the main water supply. Ensure the volume control handle is fully open. Verify that the iBox universal plus rough is receiving adequate water pressure.
- Incorrect Water Temperature: Ensure the temperature control handle is adjusted correctly. If the temperature is consistently too hot or cold, the thermostatic cartridge may require calibration or replacement by a professional.
- Leaks: If leaks occur around the trim, ensure all connections are secure. Do not overtighten. If leaks persist, professional assistance is required as it may indicate an issue with the iBox installation or internal components.
For persistent problems or issues beyond basic troubleshooting, contact a licensed plumber or hansgrohe customer support for assistance.
