5. Operating Instructions
5.1 Controller Overview
The controller features an LED display and several buttons for easy operation:
- S Button: Mode selection / Time setting.
- M Button: Cycle through wave modes / Adjust settings.
- F Button: Feeding mode activation.
- + Button: Increase flow rate / frequency.
- - Button: Decrease flow rate / frequency.
5.2 Wave Modes
The controller offers various wave modes to simulate natural water conditions:
- Constant Flow Mode: Provides a steady, continuous water flow.
- Classic Wave Mode: Generates regular wave patterns.
- Nutrition Transmission Wave: Slow and smooth wave for proper food distribution.
- Random Mode: Varies flow patterns to mimic unpredictable ocean currents.
- Night Mode: Automatically reduces pump speed during low light conditions.
5.3 Adjusting Flow Rate and Frequency
Use the + and - buttons to adjust the intensity and frequency of the water flow within the selected wave mode. Refer to the controller's display for current settings.
5.4 Feeding Mode
Press the F button to activate the 10-minute feeding mode. The pump will slow down significantly to prevent food from being quickly drawn into filtration systems, allowing fish to feed effectively. The pump will automatically resume its previous operating mode after 10 minutes.
5.5 Night Sensor
The integrated night sensor automatically detects when aquarium lights go out. In night mode, the pump's speed will be reduced to a lower, constant flow to simulate calmer nighttime conditions, minimizing stress for your aquatic inhabitants.
6. Maintenance
6.1 Cleaning the Pump
Regular cleaning is essential for optimal performance and longevity of your wave maker:
- Unplug the pump from the power source.
- Carefully remove the pump from the aquarium.
- Disassemble the pump housing and remove the impeller.
- Clean the impeller and pump housing thoroughly with a soft brush and clean water to remove any algae, debris, or calcium buildup.
- Rinse all components with clean water and reassemble the pump.
- Reinstall the pump in the aquarium and reconnect to power.
6.2 Regular Checks
Periodically inspect the power cord, connections, and magnetic bracket for any signs of wear, damage, or corrosion. Ensure all connections are secure.
7. Troubleshooting
If you encounter issues with your Jebao SOW-3N Wave Maker, refer to the following common problems and solutions:
- Pump Not Running:
- Check if the power adapter is securely plugged into the outlet and the controller.
- Ensure the pump cable is properly connected to the controller.
- Verify that the power outlet is functional.
- Weak or Intermittent Flow:
- Clean the pump and impeller as described in the Maintenance section. Debris can obstruct the impeller.
- Check the selected flow rate and frequency settings on the controller; increase if necessary.
- Ensure the pump is not in feeding mode or night mode, which reduce flow.
- Unusual Noise:
- Clean the impeller and check for any foreign objects lodged inside the pump.
- Ensure the pump is securely mounted and not vibrating against the aquarium glass.
- Controller Display Not Working:
- Check all power connections to the controller.
- If the issue persists, contact customer support.
