3. Setup and Installation
The Hansgrohe Focus E2 sink mixer is designed for single-hole deck mounting. Follow these steps for proper installation:
- Prepare the Mounting Surface: Ensure the sink or countertop has a single mounting hole of the appropriate diameter (typically around 34mm, refer to technical drawing for exact dimensions). The maximum mounting thickness is 60mm.
- Connect Hoses: Attach the G ⅜ connecting hoses to the mixer body. Ensure a secure, watertight connection.
- Insert Mixer: Place the mixer into the mounting hole.
- Secure Mixer: From underneath the sink, slide the rubber gasket, metal washer, and mounting nut onto the threaded rod. Tighten the mounting nut securely to prevent movement.
- Connect Water Supply: Connect the hot and cold water supply lines to the corresponding G ⅜ connecting hoses. For low-pressure systems, ensure the connections are made correctly to the under-counter unit.
- Check for Leaks: Slowly turn on the main water supply and check all connections for leaks.

4. Operating Instructions
The Hansgrohe Focus E2 is a single-lever mixer, providing easy control over water flow and temperature.
- Water Flow Control: Lift the lever upwards to increase water flow. Push it downwards to decrease or shut off the flow.
- Temperature Control: Move the lever to the left for hot water and to the right for cold water. The further you move it, the higher the proportion of hot or cold water.
- Spout Swivel: The fixed spout can be swiveled 150° to direct the water flow as needed within the sink area.
5. Maintenance and Care
Proper care will ensure the lasting beauty and functionality of your Hansgrohe mixer.
- Cleaning the Chrome Finish: Clean the mixer with a soft cloth and a mild, non-abrasive cleaning agent. Avoid using cleaners containing alcohol, hydrochloric acid, formic acid, acetic acid, or phosphoric acid, as these can damage the chrome finish. Rinse thoroughly with clean water after cleaning and dry with a soft cloth.
- Aerator Maintenance: Over time, mineral deposits can accumulate in the aerator (the tip of the spout), reducing water flow. Unscrew the aerator, clean it by rinsing under running water or soaking in a descaling solution (e.g., vinegar and water), and then reattach it.
- Ceramic Cartridge: The ceramic cartridge is designed for long-term, maintenance-free operation. If you experience persistent drips or stiffness in the handle, it may indicate a need for professional service.
6. Troubleshooting
If you encounter issues with your mixer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Low water flow | Clogged aerator; partially closed stopcock; debris in supply lines. | Clean or replace aerator; ensure stopcocks are fully open; flush supply lines. |
| Leaking from spout | Worn ceramic cartridge; debris in cartridge. | Contact customer support for cartridge replacement or service. |
| Leaking at connections | Loose connections; damaged seals. | Tighten connections carefully; replace seals if damaged. |
| Stiff handle operation | Mineral buildup in cartridge; worn cartridge. | Contact customer support for service. |
