4. Setup Instructions
- Placement: Position the clarifier unit in a location that avoids direct sunlight to maximize its lifespan. The unit can be installed either vertically or horizontally.
- Connect Tubing: Select the appropriate fittings (3/4", 1", 1-1/4", or 1-1/2") for your pump and tubing. Securely attach the inlet and outlet tubing to the clarifier. Ensure all connections are watertight.
- Electrical Connection: Connect the clarifier's power cord to the provided 22 Ft. weather-resistant transformer. Plug the transformer into a suitable outdoor-rated electrical outlet. Ensure the outlet is properly earthed.

5. Operating Instructions
The Jebao PU-36 Clarifier operates continuously to treat pond or aquarium water. Once powered on, the internal UV lamp will activate, exposing the circulating water to ultraviolet light. This process effectively eliminates single-celled algae and harmful bacteria, leading to clearer and healthier water.
A visual flow indicator is integrated into the unit, allowing you to confirm that water is flowing through the clarifier. Observe this indicator periodically to ensure proper operation.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your clarifier.
- Bulb Replacement: For peak performance, the 36W 2G11 UV light bulb should be replaced after approximately 8,000 hours of operation (roughly every 6-12 months, depending on continuous use).
- Cleaning: Periodically inspect the quartz sleeve (which protects the UV bulb) for mineral deposits or algae buildup. Disconnect power, remove the bulb, and carefully clean the quartz sleeve with a soft cloth and a mild cleaning solution if necessary. Rinse thoroughly before reassembly.
- Fittings Check: Ensure all fittings remain secure and free of leaks.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Green water persists | UV bulb needs replacement; insufficient flow rate; clarifier undersized for pond volume. | Replace UV bulb (every 6-12 months). Check pump and tubing for blockages. Ensure clarifier is appropriate for your pond size (up to 8,000 gallons). |
| No light from indicator | Power not connected; faulty bulb; faulty transformer. | Check power connection. Replace UV bulb. Test transformer with another device or replace if faulty. |
| Water leakage | Loose fittings; damaged O-rings. | Tighten all fittings. Inspect and replace any damaged O-rings. |
