5. Operating Instructions
The EBV-500-A flushometer operates automatically, providing a touchless experience:
- Automatic Activation: The infrared side-mount sensor detects the user. After the user departs, the flushometer automatically activates, initiating a flush cycle.
- Manual Override Button: A non-hold open mechanical override button is integrated into the unit, allowing for manual flushing when desired. Press the button to activate a flush.
- Sentinel Flush: To maintain optimal hygiene and prevent stagnant water, the unit performs a 72-hour sentinel flush. This ensures the system flushes periodically even during extended periods of infrequent use.
- Extended Battery Life: The unit is powered by batteries with an estimated life of three years, based on approximately 4,000 flush cycles per month.
6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Sloan EBV-500-A flushometer:
- Cleaning: Regularly clean the sensor lens and the exterior of the unit with a soft, damp cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the chrome finish and sensor components.
- Battery Replacement: Replace batteries when the low battery indicator (if applicable) illuminates or if flush cycles become inconsistent or cease. To replace batteries, turn off the water supply, carefully remove the unit, replace the batteries, and then re-install and recalibrate as per the installation steps.
- Diaphragm Inspection: For issues related to flush volume or consistency, a professional plumber may need to inspect the flushometer diaphragm.
7. Troubleshooting
Refer to the following table for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No flush when sensor activated | Water supply off, dirty sensor lens, dead batteries, sensor obstruction. | Check water supply valve. Clean sensor lens. Replace batteries. Remove any objects blocking the sensor's view. |
| Continuous flush | Sensor obstruction, improper calibration, faulty diaphragm. | Remove obstructions from sensor's view. Re-calibrate sensor (power cycle). If issue persists, contact a professional plumber to inspect the diaphragm. |
| Weak or incomplete flush | Low water pressure, partially closed stop valve, clogged diaphragm. | Verify adequate water pressure. Ensure the stop valve is fully open. Contact a professional plumber to inspect and clean/replace the diaphragm. |
| Manual override button not working | Mechanical issue with button or internal linkage. | Ensure the button is not jammed. If the issue persists, contact Sloan customer support for assistance. |
