2. Safety Information
Observe the following safety precautions to prevent injury and damage to the pump:
- DO NOT PUMP FLAMMABLE LIQUIDS: This pump is designed for clean water only. Pumping flammable liquids can cause fire or explosion.
- DO NOT RUN DRY: Always ensure the pump is primed with water before operation. Running the pump dry can cause damage to the impeller and motor.
- POWER SOURCE: Use only a 12V DC power source with sufficient capacity (recommended 300W or larger battery capacity). Ensure correct polarity when connecting battery clamps.
- ELECTRICAL SAFETY: The pump has a waterproof built-in switch. Keep electrical connections dry and avoid operating in standing water.
- WATER INLET/OUTLET: Add water or edible oil to the water inlet and outlet before use to wet the impeller and improve lubrication.
- IMPELLER: Wait for more than 30 seconds after priming to ensure smooth water flow.
- SUBMERGING: Do not submerge the pump in water. It is not designed for submersible operation.
- WATER LEVEL: Switch off the power immediately when the water level drops below 1/8 inch to prevent dry running.

4. Setup Instructions
Follow these steps to set up your water transfer pump:
- Connect Hoses: Attach one 6 ft water hose to the pump's inlet port and the other 6 ft hose to the outlet port. Ensure connections are secure to prevent leaks. The hoses feature 3/4 GHT (Garden Hose Thread) brass connectors.
- Install Suction Strainer: For water intake from pools, ponds, or other open sources, attach the suction strainer to the end of the inlet hose. This prevents debris from entering the pump.
- Prime the Pump: Before connecting power, add water or edible oil to both the inlet and outlet ports to wet the impeller and ensure proper lubrication. This is crucial to prevent dry running.
- Position the Pump: Place the pump on a stable, dry surface near the water source. Ensure the inlet hose is submerged in the water source and the outlet hose is directed to the desired discharge location. The pump is not submersible.
- Connect Power: Connect the red power clamp to the positive (+) terminal of a 12V DC battery and the black power clamp to the negative (-) terminal. Ensure the inline safety switch is in the "OFF" position before connecting.

5. Operating Instructions
Once the pump is set up, follow these steps for operation:
- Start the Pump: Flip the inline safety switch to the "ON" position. The pump will begin to operate.
- Monitor Flow: Allow approximately 30 seconds for the pump to establish a smooth water flow, especially after initial priming.
- Observe Water Level: Continuously monitor the water level at the inlet source. If the water level drops below 1/8 inch, immediately switch the pump "OFF" to prevent dry running and potential damage.
- Stop the Pump: When water transfer is complete or if an issue arises, flip the inline safety switch to the "OFF" position.
- Disconnect Power: After turning off the pump, disconnect the power clamps from the battery terminals.

8. Troubleshooting
Refer to the table below for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power; incorrect battery connection; switch off. | Check battery connections and charge; ensure switch is ON. |
| Pump runs but no water flows | Pump not primed; inlet hose not submerged; clogged strainer; air leak in inlet hose. | Prime the pump; ensure inlet hose is fully submerged; clean strainer; check hose connections for tightness. |
| Low flow rate | Partially clogged strainer/hose; low battery power; worn impeller. | Clean strainer/hoses; ensure battery is fully charged and sufficient capacity; inspect/replace impeller. |
| Pump is noisy | Dry running; air in the system; pump not stable. | Ensure pump is primed and continuously supplied with water; check for air leaks; place pump on a firm, level surface. |
