2. Safety Information
Important Safety Instructions: Always follow basic safety precautions to reduce the risk of fire, electric shock, and personal injury.
- Power Supply Verification: Before connecting the pump, ensure that the power supply voltage (DC24V) is consistent with the pump's requirements. Incorrect voltage can cause damage to the pump.
- Water Source Protection: If the water source contains debris or other foreign matter, place the pump inside a protective bamboo basket or similar filter to prevent clogging of the pump's intake. Clogging can reduce efficiency and damage the pump.
- Handling and Installation: The pump must be lowered and raised using a strong rope attached to its designated handle. Never pull the pump by its electrical cable, as this can damage the cable and internal connections, leading to electrical hazards or pump failure.
- Dry Running Prevention: This is a submersible pump. Do not run the pump dry (without water), as this will cause severe damage to the motor and seals. Ensure the pump is fully submerged before operation.
- Electrical Connections: All electrical connections should be made by a qualified professional and comply with local electrical codes. Ensure all connections are waterproof and secure.
- Children and Pets: Keep children and pets away from the pump and its operating area during use.
3. Setup and Installation
Proper installation is crucial for the optimal performance and longevity of your solar water pump.
- Unpacking: Carefully remove all components from the packaging. Verify that all parts listed in the package contents are present.
- Connect Accessories: Attach the provided connector and washer to the pump's interface. Ensure a tight and leak-free seal. The interface outer diameter is approximately 25mm (1 inch).
- Cable Management: The pump comes with a 14-meter (45.9 ft) cable. Ensure the cable is not kinked or damaged.
- Submersion: Securely attach a strong rope to the pump's handle. Gently lower the pump into the water source, ensuring it is fully submerged before connecting power. Remember to use a protective basket if the water source contains debris.
- Power Connection (Solar Panel): The pump has a built-in controller and can be directly connected to a solar panel. Connect the pump's DC24V cable to your solar panel system, ensuring correct polarity (+ to + and - to -). A solar charge controller and battery may be integrated into your system for consistent power supply, as illustrated below.

4. Operating Instructions
Once the pump is correctly installed and fully submerged:
- Power On: Connect the solar panel to the pump. If using a system with a switch, turn the switch to the "ON" position.
- Monitor Operation: The pump should begin to draw water. Observe the water flow to ensure proper operation.
- Continuous Operation: The pump is designed for continuous operation when sufficient solar power is available.
- Power Off: To stop the pump, disconnect the solar panel or turn off the system switch.
5. Maintenance
Regular maintenance ensures the longevity and efficient performance of your pump.
- Regular Cleaning: Periodically remove the pump from the water and inspect the intake for any accumulated debris. Clean as necessary to prevent clogging.
- Cable Inspection: Regularly check the power cable for any signs of wear, cuts, or damage. Replace if necessary.
- Connection Check: Ensure all electrical and pipe connections remain secure and watertight.
- Winterization (if applicable): In freezing climates, remove the pump from the water before temperatures drop below freezing. Clean it thoroughly and store it in a dry, frost-free location.
6. Troubleshooting
If you encounter issues with your pump, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power supply; Incorrect wiring; Low solar irradiance; Damaged cable. | Check solar panel connection and output; Verify wiring polarity; Ensure sufficient sunlight; Inspect cable for damage. |
| Low water flow | Clogged intake; Air in the system; Insufficient water level; Damaged impeller. | Clean pump intake; Ensure pump is fully submerged; Check water level; Inspect impeller for damage. |
| Pump runs but no water | Pump not fully submerged; Airlock; Suction line leak. | Ensure pump is completely underwater; Bleed air from the system; Check all connections for leaks. |
| Pump stops unexpectedly | Intermittent power supply; Overheating; Debris blockage. | Check solar panel connection stability; Allow pump to cool; Clear any blockages. |
If the problem persists after attempting these solutions, please contact the manufacturer or a qualified service technician.
