Setup and Installation

Installation of the EBV-138-A assembly involves replacing an existing cover, ring, and sensor unit on a compatible Sloan G2 or ECOS flushometer. Due to the integration of plumbing and electronic components, professional installation by a qualified plumber is strongly recommended to ensure correct setup and prevent potential issues.

General Installation Steps:

Turn Off Water Supply: Locate the main water shut-off valve for the flushometer or the entire facility and turn it off completely. Flush the toilet to relieve any remaining water pressure.
Remove Existing Assembly: Carefully remove the existing cover and sensor assembly from the flushometer. This may involve unscrewing retaining nuts or clips.
Disconnect Wiring: Disconnect any electrical wiring or sensor connections from the old assembly. Note the orientation and connection points for reassembly.
Install New Assembly: Position the new EBV-138-A cover, ring, and sensor assembly onto the flushometer. Ensure all components are correctly aligned.
Connect Wiring: Reconnect the electrical wiring and sensor connections securely.
Secure Assembly: Fasten the new assembly in place using the appropriate retaining nuts or clips, ensuring a snug fit without overtightening.
Restore Water Supply: Slowly turn the water supply back on and check for any leaks around the flushometer connections.
Test Operation: Test the flushometer's operation to ensure it functions correctly.

Note: These are general steps. Always refer to the specific installation guide provided with your Sloan G2 or ECOS flushometer for detailed, model-specific instructions.

Operating Instructions

Once the Sloan EBV-138-A sensor assembly is correctly installed, it enables hands-free operation of your water closet flushometer. The infrared sensor detects user presence and initiates a flush cycle after the user departs.

Sensor Operation:

Detection: The sensor will detect your presence when you approach the fixture.
Automatic Flush: Upon departure from the sensor's detection zone, the sensor will activate the flushometer, initiating a flush.
Manual Override (if applicable): If your flushometer model is equipped with a manual override button, it can be pressed to initiate a flush at any time, regardless of sensor detection.

Maintenance

Regular maintenance helps ensure the optimal performance and longevity of your Sloan EBV-138-A sensor assembly and flushometer.

Cleaning the Sensor Lens: Periodically clean the sensor lens window to ensure proper operation. Use a soft, damp cloth and a mild, non-abrasive soap. Avoid harsh chemicals, abrasive cleaners, or scouring pads, as these can damage the lens or sensor components.
Leak Inspection: Regularly inspect all connections around the flushometer for any signs of leaks. Address any leaks promptly to prevent water waste and potential damage to the surrounding area.
Battery Replacement: If your specific flushometer model requires batteries for the sensor assembly (the EBV-138-A requires 4 AA batteries for operation, though they are not included with this assembly), monitor their charge level. Replace batteries as needed, following the instructions in your flushometer's manual, to ensure continuous and reliable operation.
Obstruction Check: Ensure that there are no objects obstructing the sensor's field of view, as this can interfere with proper detection and flushing.

Troubleshooting

This section addresses common issues you might encounter with your Sloan EBV-138-A sensor assembly and flushometer.

Issue	Possible Cause	Solution
Flushometer does not flush automatically.	Obstructed or dirty sensor lens. Low or dead batteries (if applicable). Water supply turned off or restricted. Improper sensor alignment or connection.	Clean the sensor lens with a soft, damp cloth. Replace batteries if necessary (4 AA batteries required for operation). Ensure the water supply valve to the flushometer is fully open. Verify the sensor assembly is correctly installed and all connections are secure.
Continuous flushing or dripping.	Internal flushometer component issue (e.g., worn diaphragm). Debris in the flushometer valve.	Turn off the water supply to the flushometer immediately. This typically indicates an issue with the flushometer's internal mechanism, not the sensor assembly itself. Consult a qualified plumber for inspection and repair.
Weak or incomplete flush.	Insufficient water pressure. Partially closed water supply valve. Blockage in the flushometer or toilet bowl.	Ensure the water supply valve is fully open. Check the building's water pressure. Inspect for any visible blockages. Professional assessment may be required.
