4. Setup
4.1 Mounting the Wavemaker
The OW-25 Wavemaker uses a magnet mount for secure placement within your aquarium. Choose a location that allows for optimal water flow distribution without disturbing substrate or delicate corals.
- Place the wavemaker unit (with the internal magnet) inside the aquarium, ensuring it is fully submerged.
- Align the external magnet on the outside of the aquarium glass, directly opposite the internal magnet. The strong magnetic force will hold the wavemaker in place.
- Adjust the position and angle of the wavemaker as needed to direct water flow.

4.2 Connecting the Controller and Power
- Connect the wavemaker pump unit cable to the designated port on the controller.
- Connect the power supply adapter to the controller.
- Plug the power supply adapter into a suitable electrical outlet.
- Ensure all connections are secure before powering on.
5. Operating Instructions
The Jebao OW-25 Wavemaker controller allows for various adjustments to customize water flow. Familiarize yourself with the controller's layout and functions.

Image 5.1: Overview of the Jebao Wavemaker controller with labeled functions.
Controller Functions:
- Speed Control: Adjusts the overall power/speed of the wavemaker.
- Wavemaker Mode (W1, W2, Else, H, C): Selects different flow patterns.
- W1: Classic Wave Mode - Creates a uniform wave pattern.
- W2: Sine Wave Mode - Generates a smoother, more natural wave.
- Else: Random Flow Mode - Varies flow intensity and direction randomly.
- H: Constant Flow Mode - Maintains a steady, continuous flow.
- C: Feed Mode - Not a flow mode, but activates the feed function.
- Speed/Feeding Button: Press to activate feed mode (pump slows for 10 minutes). Hold to adjust speed.
- Mode/Night Button: Press to cycle through wave modes. Hold to activate/deactivate Night Mode (uses light sensor to reduce flow in darkness).
- WI-LE (Wireless Link) Button: Used for Master/Slave setup. Press to set a unit as Master or Slave.
- Rotate Control Knob: Fine-tunes speed or wave intensity depending on the selected mode.
- Auto Light Sensor: Detects ambient light for Night Mode activation.
Master/Slave Wireless Mode:
To synchronize multiple OW-25 wavemakers, designate one as the Master and others as Slaves using the WI-LE button. The Slave units will mimic the Master's settings, creating coordinated water movement.
6. Maintenance
Regular cleaning of your wavemaker is essential for optimal performance and longevity. Detritus and mineral buildup can reduce efficiency and cause noise.
Cleaning Procedure:
- Disconnect Power: Always unplug the wavemaker from the power outlet before cleaning.
- Remove from Aquarium: Carefully detach the wavemaker from the magnet mount and remove it from the water.
- Disassemble: The OW-25 is designed for easy disassembly. Gently twist and pull apart the pump housing to access the impeller and motor components.
- Clean Components: Use a soft brush (e.g., a toothbrush) and clean water to remove any algae, detritus, or mineral deposits from the impeller, impeller shaft, and pump housing. For stubborn mineral buildup, a diluted vinegar solution can be used, followed by thorough rinsing.
- Inspect: Check the impeller and shaft for any signs of wear or damage. Replace if necessary.
- Reassemble: Carefully reassemble the wavemaker, ensuring all parts fit correctly.
- Reinstall: Place the cleaned wavemaker back into the aquarium and reconnect the power.
