Operating Instructions
LCD Controller Functions
The LCD controller allows for precise control over the pump's operation:
- Power Button: Turns the pump ON/OFF.
- MODE Button: Cycles through different operating modes (Constant Flow, Feed Mode, Wave Maker Mode).
- +/- Buttons: Adjust the flow rate or duration depending on the selected mode.
- LCD Display: Shows current mode, flow rate, or timer settings.
Operating Modes
- Constant Flow Mode: Adjust the flow rate from minimum to maximum using the +/- buttons. The display will show the current power level.
- Feed Mode: Activates a temporary pause in pump operation for feeding fish or other aquatic life. Press the MODE button to enter Feed Mode, and use +/- to set the duration of the pause (e.g., 10, 20, or 30 minutes). The pump will resume normal operation automatically after the set time.
- Wave Maker Mode: Creates oscillating water flow to simulate natural wave patterns. Use the +/- buttons to adjust the intensity or frequency of the waves.

Maintenance
Regular maintenance ensures optimal performance and longevity of your pump.
1. Cleaning the Impeller and Intake Screens
- Unplug the pump from the power source.
- Remove the intake screen by gently twisting or unclipping it.
- Carefully remove the impeller cover and then the impeller itself.
- Clean the impeller and its housing with a soft brush and fresh water to remove any debris or mineral buildup.
- Clean the intake screen.
- Reassemble all parts in reverse order, ensuring they are securely fitted.
2. Preventing Dry Running
The pump features IC electronic detection to prevent dry running. However, always ensure the pump is fully submerged or properly primed before operation to avoid unnecessary wear and tear.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump not running | No power, clogged impeller, dry run protection activated. | Check power connection, clean impeller, ensure pump is submerged/primed. |
| Reduced flow rate | Clogged intake screen/impeller, kinked tubing, incorrect flow setting. | Clean intake/impeller, check tubing for obstructions, adjust flow rate on controller. |
| Unusual noise | Debris in impeller, worn impeller, pump not stable. | Clean impeller, inspect for damage, ensure stable placement. |
| Error message on LCD | Specific error code (e.g., dry run, locked rotor). | Refer to the controller's specific error code guide in the full manual for detailed solutions. Generally, check for obstructions or water levels. |
