2. Safety Instructions
Please read and understand all safety instructions before operating the Jebao Jecod ECP-50 Wave Maker Pump. Failure to follow these instructions may result in product damage, injury, or electrical shock.

4. Installation and Setup
Follow these steps to properly install your ECP-50 Wave Maker Pump:
- Mounting the Pump:
- Ensure the aquarium glass thickness is less than 8mm (0.31 inches).
- Place the pump unit inside the aquarium, ensuring it is fully submerged.
- Align the external magnetic mount on the outside of the aquarium glass, directly opposite the pump unit. The strong magnets will secure the pump in place.
- Adjust the pump's position and angle to direct water flow as desired.
- Connecting the Controller:
- Connect the pump's cable to the designated port on the external controller.
- Connect the power adapter to the controller's power input port.
- Plug the power adapter into a suitable electrical outlet, ensuring a drip loop is formed with the power cord.
- Initial Power-Up:
- Once powered, the controller display will illuminate, and the pump will begin operation in its default mode.
- Refer to the "Operating Instructions" section to customize settings.
- Master and Slave Group Use (Optional):
- If using multiple ECP series pumps, you can link them for synchronized operation.
- Designate one controller as the "Master" and others as "Slave" units according to the controller's instructions (typically via a dedicated button or menu option).
- The Master controller will then dictate the mode and intensity for all connected Slave pumps.

5. Operating Instructions
The ECP-50 controller allows you to select various wave patterns and adjust pump intensity. Familiarize yourself with the controller buttons:
- ON/OFF Button: Powers the pump on or off.
- MODE Button: Cycles through different wave patterns (e.g., constant flow, pulse mode, random flow). The selected mode will be displayed on the LCD screen.
- FREQ Button: Adjusts the frequency or speed of the wave pattern in pulse or random modes.
- +/- Buttons (Up/Down Arrows): Adjusts the pump's output intensity or flow rate.
- FEED Button: Activates a temporary pause mode (typically 10 minutes) to allow for feeding without food being immediately drawn into the pump or filter. The pump will resume normal operation automatically after the set time.
Experiment with different modes and intensity settings to find the optimal water movement for your aquarium inhabitants and aquascape.
6. Maintenance
Regular maintenance ensures the longevity and efficient operation of your ECP-50 Wave Maker Pump.
- Disassembly:
- Always unplug the power adapter before attempting any maintenance.
- Carefully remove the pump unit from the aquarium.
- Disassemble the pump housing by twisting or unlatching the components as per the design to access the impeller.
- Cleaning:
- Rinse all pump components, including the impeller and housing, under clean running water.
- Use a soft brush or cotton swab to remove any algae, detritus, or mineral deposits from the impeller, impeller shaft, and inside the pump housing.
- For stubborn mineral deposits, a diluted vinegar solution can be used, followed by a thorough rinse with fresh water.
- Reassembly:
- Ensure all components are clean and free of debris before reassembly.
- Carefully reassemble the pump, ensuring all parts fit securely.
- Place the pump back into the aquarium and reconnect the power.
Perform cleaning at least once a month, or more frequently if you notice reduced flow or increased noise.
7. Troubleshooting
If you encounter issues with your ECP-50 Wave Maker Pump, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump not turning on. | No power, loose connection, damaged power adapter/controller. | Check power outlet. Ensure all connections are secure. Inspect power adapter and controller for visible damage. |
| Reduced water flow. | Impeller clogged with debris/algae, mineral buildup, pump positioned incorrectly. | Disconnect power and clean the impeller and pump housing thoroughly. Adjust pump position for optimal flow. |
| Excessive noise or vibration. | Impeller obstructed, worn impeller, improper mounting, air trapped in pump. | Disconnect power and clean the impeller. Ensure the pump is securely mounted and fully submerged. Gently shake the pump to release trapped air. |
| Controller display not working. | No power, damaged controller. | Check power connection. If power is present and other components work, the controller may be faulty. |
