2. Important Safety Instructions
- Read all instructions carefully before using the appliance.
- Do not operate any appliance if it has a damaged cord or plug, or if it malfunctions or has been dropped or damaged in any manner.
- To avoid the possibility of the appliance plug or receptacle getting wet, position the aquarium stand and tank to one side of a wall-mounted receptacle to prevent water from dripping onto the receptacle or plug.
- A "drip loop" should be arranged by the user for each cord connecting an aquarium appliance to a receptacle. The drip loop is the part of the cord below the level of the receptacle, or the connector if an extension cord is used, to prevent water from traveling along the cord and coming into contact with the receptacle.
- Always unplug the appliance from the outlet when not in use, before putting on or taking off parts, and before cleaning. Never yank cord to pull plug from outlet. Grasp the plug and pull to disconnect.
- Do not use the appliance for anything other than its intended use.
- Do not install or store the appliance where it will be exposed to the weather or to temperatures below freezing.
- Ensure the wave maker is fully submerged in water during operation.
- Keep out of reach of children.

4.2 Key Features
- 6 Wave Maker Modes: Constant, Pulse, Tide, Random, Quick, FWD/REV.
- Adjustable Wave Length and Flow Rate: Customize water movement for various aquarium needs.
- Rotatable Wide Wave Outlet: Directs water flow in multiple angles, reducing impact on fish and plants.
- Night Mode: Automatically switches to a lower flow rate when ambient light dims, promoting fish rest.
- Feeding Mode: Temporarily pauses the pump for 10 minutes during feeding.
- Wireless Connection: Allows multiple pumps to operate alternately under a single master controller.
- Memory Function: Retains settings after power loss.
- Low Water Level Protection: Automatically stops operation if water level is too low.
- Strong Magnetic Base: Secure and easy installation/removal, with silicone sleeve for noise reduction and tank protection.

5. Installation and Setup
5.1 Connecting Components
- Connect the wave maker pump unit cable to the controller.
- Connect the power adapter to the controller.
- Plug the power adapter into a suitable electrical outlet, ensuring a drip loop is formed.

5.2 Mounting the Wave Maker
- Place the wave maker pump unit inside the aquarium, ensuring it is fully submerged.
- Attach the external magnetic holder to the outside of the aquarium glass, aligning it with the internal pump unit. The strong magnets will secure the pump in place.
- Ensure the silicone sleeve on the magnetic holder is properly positioned to prevent scratching the tank wall and reduce noise.
- Position the pump to direct water flow as desired. The outlet can be rotated to adjust direction.

5.3 Initial Power-On and Low Water Protection
Once connected and mounted, the unit will power on. The controller will display current settings. The wave maker is equipped with low water level protection. If the water level in the aquarium is too low, the pump will automatically stop operating to prevent damage. Ensure the pump is always fully submerged during operation.

6. Operation
6.1 Controller Functions
The external controller allows for easy adjustment of all settings:
- Power Button: Turns the wave maker ON/OFF.
- Mode Buttons: Select from the 6 wave modes (Pulse, Constant, Tide, Random, Quick, FWD/REV).
- Night Mode Button: Activates or deactivates the automatic low flow night mode.
- Feed Rate Button: Initiates a 10-minute pause for feeding.
- Lock/Link Button: Locks current settings or initiates wireless linking for multiple pumps.
- Adjustment Knob: Used to adjust flow rate (Flow 1-10) and wave length.
- Night Sensor: Detects ambient light levels for automatic night mode activation.
6.2 Wave Maker Modes
The wave maker offers six distinct modes to simulate various natural water movements:
- Constant Mode: Provides a continuous, fixed waveform output water flow.

- Pulse Mode: The motor quickly pushes out a wave at maximum power, then drops to minimum power, repeating the cycle.
- Tide Mode: The motor slowly increases to maximum speed and then slowly decreases, mimicking the rise and fall of tides.
- Random Mode: The flow rate has no standard rhythm, operating randomly to create turbulent water movement.

- Quick Mode: The motor runs fast, providing a constant and strong flow of water.
- FWD/REV Mode: The waveform operates alternately in forward and reverse directions.
6.3 Night Mode
The external controller includes a light sensor. When the room light dims, the sensor activates, and the wave pump defaults to the lowest flow rate (1st speed) of the current mode. When the light brightens, it automatically returns to the previously set normal mode. This mode can be toggled ON/OFF using the Night Mode button.

6.4 Feeding Mode
During daily feeding, press the Feed Rate button on the controller. The wave pump will temporarily stop running for ten minutes, allowing fish to feed without strong water circulation. After ten minutes, the pump will automatically resume its previous operation.
6.5 Wireless Connection Mode (for multiple pumps)
For aquariums requiring multiple wave makers, this feature allows wireless synchronization. One controller acts as the master, and others as slaves. Each pump head operates alternately, sharing the master controller's settings. Refer to the controller's specific instructions for pairing multiple units.

7. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your wave maker.
7.1 Cleaning the Pump Unit
- Unplug the power adapter before performing any maintenance.
- Carefully remove the wave maker pump unit from the aquarium.
- Disassemble the pump unit according to the diagrams (if provided in the physical manual) to access the impeller and internal components.
- Clean any algae, debris, or mineral deposits from the impeller, housing, and outlets using a soft brush and clean water. For stubborn deposits, a mild vinegar solution can be used, followed by thorough rinsing.
- Ensure all parts are clean and free of obstructions before reassembling and reinstalling.
7.2 Controller Care
- Keep the controller dry and away from water splashes.
- Wipe the controller surface with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
8. Troubleshooting
If you encounter issues with your hygger Intelligent Wave Maker, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump not running / No power | Power adapter unplugged, power outage, faulty connection, low water level protection activated. | Check power connections. Ensure the power outlet is functional. Verify water level is sufficient. Check for damaged cables. |
| Weak or inconsistent flow | Impeller clogged with debris/algae, pump not fully submerged, incorrect mode/flow setting. | Unplug and clean the impeller. Ensure pump is fully submerged. Adjust flow rate settings on the controller. |
| Excessive noise | Impeller obstruction, improper mounting, air trapped in pump, worn components. | Clean the impeller. Ensure the magnetic holder is securely and correctly positioned. Gently shake the pump to release trapped air. If noise persists, contact customer support. |
| Controller display not working | Power issue, damaged controller. | Check power connections. If power is confirmed and display remains off, the controller may be faulty; contact customer support. |
If the problem persists after attempting these solutions, please contact hygger customer support for further assistance.
