Setup and Installation
- Mounting the Pump:
- Identify the inner and outer parts of the magnetic mounting bracket.
- Place the pump unit with the inner magnet inside the aquarium, ensuring it is fully submerged.
- Align the outer magnet on the exterior glass of the aquarium, directly opposite the inner magnet. The strong magnetic force will secure the pump in place.
- Position the pump to direct flow as desired. The pump head can be rotated to adjust the flow direction.
- Connecting the Controller:
- Connect the pump's cable to the designated port on the controller. Ensure the connection is secure and the threaded nut is tightened.
- Connect the power adapter to the controller.
- Plug the power adapter into a suitable electrical outlet. It is recommended to use a drip loop to prevent water from traveling along the cord to the outlet.
Operating Instructions
The Jebao SOW controller allows for various modes and adjustments:
Controller Functions:
- SPEED/FEED Button:
- Short press to cycle through flow intensity levels (indicated by LED lights).
- Long press (approx. 3 seconds) to activate the 10-minute feed mode, slowing the pump for feeding. The "FEED" LED will illuminate. The pump will resume normal operation after 10 minutes.
- MODE/NIGHT Button:
- Short press to cycle through different wave modes (e.g., constant flow, pulse, sine wave). Refer to the controller's LED indicators for the active mode.
- Long press (approx. 3 seconds) to activate/deactivate the night sensor. When active, the pump will automatically slow down when tank lights go out (indicated by the "NIGHT" LED).
- WIFI/LOCK Button:
- This model (SOW-3) typically does not feature Wi-Fi control.
- Long press to lock/unlock the controller settings, preventing accidental changes.
Wave Modes:
The SOW series offers various wave patterns to simulate natural ocean currents. Experiment with different modes and intensity settings to find the ideal flow for your aquarium and its inhabitants.
- W1 Mode (Wave Mode): Creates a wave effect by varying flow. Adjustable by speed.
- W2 Mode (Sine Wave Mode): Produces a smooth, continuous sine wave pattern.
- Else Mode (Random Mode): Generates a random flow pattern, mimicking natural, unpredictable currents.
- H Mode (Constant Flow Mode): Provides a steady, continuous flow at a set intensity.
- C Mode (Shift to Flow Mode): For use with two pumps, creating alternating flow.
Maintenance
Regular maintenance ensures the longevity and efficient operation of your wave maker.
- Cleaning the Pump:
- Frequency: Clean the pump every 1-3 months, or more frequently if you notice reduced flow or increased noise.
- Procedure:
- Unplug the pump from the power outlet.
- Remove the pump unit from the aquarium.
- Carefully detach the front cage and impeller assembly.
- Rinse all components under clean running water to remove debris.
- For stubborn calcium deposits or algae, soak the components in a mild acid solution (e.g., vinegar or citric acid solution) for several hours, then scrub gently with a soft brush.
- Rinse thoroughly with fresh water before reassembling and returning to the aquarium.
- Cable and Connections: Periodically inspect the power cord and all connections for any signs of wear, damage, or corrosion. Ensure all connections are dry and secure.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump not running | No power; loose connection; impeller jammed; pump failure. | Check power outlet and connections. Clean impeller and pump housing. If still not working, contact support. |
| Reduced flow | Impeller or pump intake clogged with debris/algae; incorrect mode/speed setting. | Clean the pump and impeller thoroughly. Adjust speed setting on the controller. |
| Excessive noise/vibration | Air trapped in pump; impeller dirty/damaged; improper mounting. | Ensure pump is fully submerged and free of air bubbles. Clean impeller. Check magnetic mounting for secure placement. |
| Controller not responding | Power issue; controller locked. | Check power connection. Long press the LOCK button to unlock the controller. |
