5. Operating Instructions
Your hansgrohe shower system is designed for intuitive use.
- Water Flow Control (Ecostat 1001 SL): Use the left rotary control on the Ecostat 1001 SL thermostat to turn the water on/off and adjust the flow rate.
- Temperature Control (Ecostat 1001 SL): Use the right rotary control to set your desired water temperature. The thermostat maintains a constant temperature, even with pressure fluctuations. A safety stop is typically set at 38°C (100°F) to prevent accidental scalding; this can be overridden by pressing a button on the control.
- Changing Spray Types (Croma 100 Multi Hand Shower): Rotate the spray disc on the hand shower head to switch between Rain, Mono, and Massage spray types.
- Adjusting Hand Shower Height and Angle: The holder on the Unica'C shower bar allows you to slide the hand shower up or down to your preferred height. You can also tilt the hand shower by 90° and swivel it left or right to direct the water flow.
6. Maintenance
Regular cleaning and maintenance will ensure the longevity and optimal performance of your hansgrohe shower system.
- Cleaning the Surfaces: Clean the chrome surfaces with a soft cloth and a mild, non-abrasive cleaning agent. Avoid cleaners containing alcohol, hydrochloric acid, formic acid, chlorine bleach, or acetic acid, as these can damage the finish.
- QuickClean Limescale Removal: The Croma 100 Multi hand shower features QuickClean silicone nozzles. To remove limescale deposits, simply rub the silicone nozzles with your finger. This should be done regularly, especially in areas with hard water.
- Shower Hose: Periodically check the shower hose for any signs of wear or damage. The Isiflex hose is designed to be non-bending, but extreme kinks should be avoided.
- Thermostat Cartridge: If you experience consistent temperature fluctuations or difficulty adjusting the temperature, the thermostat cartridge may need cleaning or replacement. This typically requires professional service.
7. Troubleshooting
If you encounter issues with your shower system, try the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Low water flow from hand shower | Limescale buildup in nozzles or aerator; partially closed shut-off valves; clogged filter screens. | Rub QuickClean nozzles to remove limescale. Check if shut-off valves are fully open. Clean or replace filter screens in the thermostat connections. |
| Water temperature fluctuates or is incorrect | Thermostat cartridge needs calibration or cleaning; insufficient hot water supply; pressure imbalance. | Ensure adequate hot water supply. If problem persists, the thermostat cartridge may need professional inspection or replacement. |
| Leaks at connections | Loose connections; damaged seals. | Tighten connections carefully. Replace any damaged seals or gaskets. Ensure proper use of plumber's tape or sealant during installation. |
| Hand shower holder slides down | Holder mechanism is loose or worn. | Check if the tightening screw on the holder is secure. If worn, the holder may need replacement. |
If these steps do not resolve the issue, please contact hansgrohe customer support or a qualified plumber.
