3. Operating Instructions
The TOTO Helix Touchless Spout operates using an integrated electronic sensor. To activate water flow, simply place your hands within the sensor's detection range, typically directly below the spout. The sensor will detect your presence and initiate water flow.
- Automatic Shut-off: Water will flow for approximately 10 seconds. To stop the flow sooner, simply remove your hands from the sensor's range.
- Continuous Flow: If more water is needed, remove your hands and then place them back under the spout to reactivate the flow for another cycle.
- ECO CAP Technology: The spout features ECO CAP aerating technology, which mixes air into the water stream. This provides a comfortable water experience while contributing to water conservation.

4. Maintenance
Regular cleaning and proper care will ensure the longevity and aesthetic appeal of your TOTO Helix Touchless Spout.
Cleaning Instructions:
- Finish Care: For the polished chrome finish, use a soft, damp cloth and a mild, non-abrasive cleaner. Wipe gently to avoid scratching the surface.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, scouring pads, ammonia-based cleaners, or any cleaners containing bleach, acids, or alcohol, as these can damage the finish and internal components.
- Sensor Cleaning: Keep the sensor window clean and free from obstructions. Use a soft, damp cloth to wipe the sensor area. Avoid spraying cleaners directly onto the sensor.
- Aerator Maintenance: Periodically check the ECO CAP aerator for mineral buildup or debris. If necessary, carefully remove the aerator (refer to the installation guide for specifics) and clean it with a soft brush under running water. Reinstall securely.
5. Troubleshooting

- Ensure the sensor window is clean and unobstructed.
- Inconsistent Water Flow or Low Pressure:
- Clean the ECO CAP aerator for any mineral buildup or debris.
- Check water pressure from the main supply.
- Sensor Not Responding:
