Operating Instructions
The Ecostat S Thermostatic Mixer provides precise control over water temperature.
Temperature Control:
- Rotate the temperature handle to adjust the water temperature.
- The integrated safety stop is set at 40°C (104°F) to prevent accidental scalding. To exceed this temperature, you must consciously override the safety stop by pressing a button or turning the handle past the stop point (refer to the specific product diagram for your model).
Flow Rate:
The flow rate of the mixer is dependent on the water pressure. This model is designed for a flow rate of up to 37 liters per minute (l/min) at 3 bar pressure.

Maintenance and Care
To ensure the longevity and optimal performance of your Hansgrohe Ecostat S Thermostatic Mixer, follow these maintenance guidelines:
- Cleaning: Clean the chrome and silver surfaces regularly with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for bathroom fixtures. Avoid harsh chemicals, abrasive pads, or cleaners containing alcohol, ammonia, or bleach, as these can damage the finish.
- Temperature Calibration: If the water temperature is not consistent with the dial setting, the thermostatic cartridge may need recalibration. Refer to the detailed assembly instructions for steps on how to recalibrate the thermostat.
- Filter Maintenance: Periodically check and clean any integrated filters to prevent debris buildup, which can affect flow rate and temperature stability.
Troubleshooting
This section addresses common issues you might encounter with your thermostatic mixer.
| Problem | Possible Cause | Solution |
|---|---|---|
| Inconsistent water temperature | Thermostatic cartridge needs calibration; fluctuating water pressure; clogged filters. | Recalibrate the thermostat (refer to manual); check household water pressure; clean filters. |
| Low water flow | Clogged filters; low water pressure; partially closed shut-off valve. | Clean filters; check household water pressure; ensure shut-off valve is fully open. |
| Water not reaching desired temperature (hot/cold) | Incorrect hot/cold water supply connection; thermostatic cartridge malfunction. | Verify hot and cold water connections; contact a qualified plumber for cartridge inspection/replacement. |
If the issue persists after attempting these solutions, it is recommended to contact a qualified plumber or Hansgrohe customer support for further assistance.
