3. INSTALLATION INSTRUCTIONS

• Detach the magnetic holder from the pump body.
• Connect the wave pump to the controller and the controller to the power adapter. Plug in and operate.
• Place the pump at least 3 inches (7-8CM) underwater and attach it to the outer glass of the aquarium using the magnetic holder.

CAUTION: Be careful not to pinch your fingers; the magnet is very strong.

4. INSTRUCTIONS FOR USING BUTTON FUNCTIONS

Function Modes:

• Flow: Adjusts the pump's flow rate.
• Frequency: Adjusts the wave frequency.
• Night: Activates a low-flow mode when light levels decrease.
• Feed: Activates a 10-minute feeding mode, with options for 20, 30, or 60-minute feeding cycles.

Wave Modes:

• Constant Wave: Allows setting of flow rate (1-20). Frequency cannot be set.
• Classic Cross-flow Wave, Sine Wave, Random Wave: Allows setting of frequency (1-20). Flow rate cannot be adjusted.

Button Operations:

• M Button: Press to select wave modes (Constant Wave → Classic Cross-flow Wave → Sine Wave → Random Wave).
• '+' / '-' Buttons: Press to adjust flow rate or frequency from 1 to 20.
• F Button: Press briefly for 10-minute feeding (Flow indicator lights up). Press again to select feeding duration (20-30-60 minutes). Press again to activate standby mode, then press again to return to normal operation.

5. HOW TO PROGRAM

To set the Constant Wave Mode and Flow Mode:

1. Briefly press the “M” button. The “Constant Wave” icon will light up, and the green “Flow” indicator will light up.
2. Press the “+” or “-” button to select the flow rate from 1 to 20. Two indicator lights will show the selected flow rate.

Attention: In Constant Wave Mode, only flow rate can be set; frequency cannot be set.

To set the Classic Cross-flow Wave Mode, Sine Wave Mode, or Random Wave Mode and Frequency:

1. Briefly press the “M” button. The icon of the selected wave mode (e.g., “Classic Wave”) will light up, and the green “Freq” indicator will light up. Press the “M” button alternately to select the desired wave mode.
2. Press the “+” or “-” button to adjust the frequency from 1 to 20.

Attention: In these modes, only frequency can be set; flow rate cannot be adjusted.

To set the Night Mode:

• The night mode is automatically switched on from the factory. The green “Night” indicator is always illuminated when the mode is active.
• The pump operates in low flow rate with “01” displayed when the light sensor detects dimming light.
• To switch off night mode: Press and hold the “M” button until the green indicator turns off.
• To switch on night mode: Press and hold the “M” button until the green “Night” indicator lights up.

How to set the Feed Time:

• Briefly press the “F” button to activate 10-minute feeding (green “Flow” indicator lights up).
• Press again to select feeding duration (20-30-60 minutes).
• Press again to activate standby mode, then press again to return to normal operation.

6. ATTENTION

• Ensure your power supply meets the pump's voltage and current frequency requirements.
• Never allow the pump to run dry for longer than 5 minutes. Ensure the device is always fully submerged to prevent overheating.
• The controller is not waterproof. Avoid contact with water to prevent electric shock and damage.
• The device is suitable for fresh and salt water. Do not use in flammable, acidic, or corrosive liquids.
• Operates in clean water between 4°C (39°F) and 35°C (95°F). Operation outside this range may cause damage.
• Never lift the device by the cable. If the cable is damaged, discontinue use for safety.
• The controller must not fall into water or be operated in high humidity environments. Ensure the controller is not placed in a dark location, as this may affect the night function.
• The pump housing is secured by a strong magnet. Ensure the magnetic sides of the holder are not brought together without protection, as they are difficult to separate.
• Store the pump in its packaging when not in use.
• Before starting up for the first time, ensure fish and invertebrates are larger than the pump's grid size to prevent them from being drawn in.
• Close supervision is necessary when the pump is used near children.
• Avoid contact with moving or hot parts to prevent injury.
• Always unplug the pump when not in use, before maintenance, or when placing hands in water. Grasp the plug firmly to disconnect.
• Do not use the pump for unintended purposes. Unauthorized attachments may void the warranty.

11. WARNING

• To avoid electric shock, do not immerse the switch in water. If the switch becomes wet, unplug it before touching. Observe basic safety precautions.
• DANGER: Special care is needed due to water use in aquarium equipment. Do not attempt self-repair. Return to an authorized service facility for maintenance or disposal.
• A. If the pump shows signs of water leakage or RCD/GFCI trip, unplug the power and remove the pump from water.
• B. Carefully examine the pump after installation. Do not plug in if water is present on unintended parts.
• C. Do not operate with a damaged cord or plug, or if malfunctioning, dropped, or damaged. The power cord is not replaceable; if damaged, discard the pump.
• D. To prevent the pump plug from getting wet, position the aquarium and outlet to avoid water dripping onto them. Arrange a "drip loop" for each cord connecting the pump to the outlet. The "drip loop" should be below the outlet level to prevent water from traveling along the cord. If the plug or outlet gets wet, DO NOT unplug. Disconnect the fuse at the circuit breaker supplying power, then unplug and examine the outlet for water. Consult a certified electrician if unsure.
• E. Close supervision is necessary when the pump is used near children.
• F. Avoid contact with moving or hot parts to prevent injury.
• G. Always unplug the pump when not in use, before maintenance, or placing hands in water. Grasp the plug firmly to disconnect.
• H. Do not use the pump for unintended purposes. Unauthorized attachments may void the warranty.
