3.2 Installation Steps
- Turn off Water Supply: Locate and turn off the main water supply to the bathroom.

4. Operating Instructions
The Roca A5A066ENB0 is a single-lever mixer with an automatic diverter, designed for intuitive control of water flow and temperature.
- Water Flow Control: Lift the single lever upwards to increase water flow. Push it downwards to decrease flow and turn off the water.
- Temperature Control: Move the single lever to the left for hot water and to the right for cold water. Adjust the position to achieve the desired temperature.
- Automatic Diverter: The mixer features an automatic diverter. When the water flow is activated, the diverter will automatically direct water to the bath spout. To switch to the shower, pull the small knob located above the main lever. The diverter will return to the bath position automatically when the water is turned off.
- Water Saving System: This mixer is equipped with a water-saving system. You may feel a slight resistance when lifting the lever to its maximum flow position, indicating the water-saving threshold. Pushing past this point will provide full flow.
5. Maintenance and Care
Proper care will ensure the longevity and appearance of your Matt Black mixer.
- Regular Cleaning: Clean the mixer regularly with a soft cloth and mild soap or a non-abrasive liquid cleaner.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, scouring pads, acids, alcohol, or solvents, as these can damage the Matt Black finish and internal components.
- Drying: After cleaning, wipe the mixer dry with a soft cloth to prevent water spots and mineral buildup.
- Aerator Maintenance: Periodically unscrew and clean the aerator (if applicable) to remove any sediment or debris that may affect water flow.
6. Troubleshooting
If you encounter issues with your mixer, refer to the following common problems and solutions:
