Controller Functions:
- Flow Adjustment: Use the + and - buttons to increase or decrease the pump's flow rate. There are 8 adjustable speed settings. The LED indicators on the controller will show the current speed level.
- Feeding Mode: Press the FEED button to activate the feeding mode. The pump will suspend operation for 10 minutes, allowing fish to feed without strong currents. After 10 minutes, the pump will automatically resume its previous operating speed.
Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your pump.
- Cleaning: Periodically remove the pump from the water and disassemble the impeller cover and impeller. Clean any accumulated debris, algae, or calcium deposits from the impeller, ceramic shaft, and pump housing. Use a soft brush and warm water. For stubborn deposits, a mild vinegar solution can be used, followed by thorough rinsing.
- Impeller Inspection: Check the ceramic shaft and impeller for any signs of wear or damage. Replace if necessary.
- Intake Screen: Ensure the intake screen is clear of obstructions to maintain proper water flow.
- Cable Inspection: Regularly inspect the power cable and controller cable for any nicks, cuts, or damage.
Troubleshooting
If you encounter issues with your pump, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump not running | No power; Controller or pump connection loose; Impeller jammed; Dry run protection activated. | Check power outlet and connections. Ensure pump is fully submerged. Clean impeller and housing. Disconnect and reconnect power to reset. |
| Low flow rate | Impeller or intake screen clogged; Tubing kinked or obstructed; Pump speed set too low. | Clean impeller and intake screen. Check and clear tubing. Increase pump speed using the controller. |
| Excessive noise/vibration | Debris in impeller; Impeller worn or damaged; Pump not stable. | Clean impeller. Inspect and replace worn impeller/shaft. Ensure pump is placed on a stable surface. |
| Pump cycles on/off | Dry run protection activating due to low water level or air in pump. | Ensure adequate water level. Bleed any trapped air from the pump by tilting it while submerged. |
