2. Safety Instructions
To prevent injury or damage to the pump, always observe the following safety precautions:
- Electrical Safety: Ensure the power supply voltage matches the pump's requirements (220-240V/50Hz). Do not operate the pump with a damaged power cord or plug. Always disconnect power before handling or performing maintenance on the pump.
- Full Submersion: The pump must be completely immersed in water during operation. Never run the pump dry (idling without water), as this will cause overheating and permanent damage.
- Water Temperature: The working water temperature must not exceed 35 °C (95 °F). Operating the pump in water hotter than this limit can lead to malfunction or damage.
- Proper Placement: Place the pump on a stable, flat surface within the water. Ensure it is not obstructed by debris.
- Handling: Do not lift or carry the pump by its power cord. Use the pump body for handling.
- Children and Pets: Keep the pump and its power cord out of reach of children and pets.
3. Setup
Follow these steps for proper installation of your HB-704 Submersible Pump:
- Unpack the Pump: Carefully remove the pump from its packaging and inspect it for any signs of damage.
- Attach Hose: Connect a hose with an inner diameter of 12mm to the pump's outlet nozzle (approximately 13mm in diameter). Ensure a secure fit to prevent leaks.
- Position the Pump: Place the pump in the desired location within the water reservoir or container. Ensure the pump is fully submerged and resting on a stable surface. The integrated suction cups on the bottom of the pump can help secure it in place.
- Route Power Cord: Route the 130cm long power cord safely, ensuring it does not create a tripping hazard and is not pinched or kinked.
- Verify Submersion: Double-check that the entire pump body is completely underwater before connecting to power.

4. Operating Instructions
Once the pump is properly set up and fully submerged:
- Connect to Power: Plug the power cord into a suitable electrical outlet (220-240V/50Hz). The pump will begin operating immediately.
- Monitor Water Level: Continuously monitor the water level to ensure the pump remains fully submerged during operation. Running the pump without water will cause damage.
- Observe Flow: Check the water flow from the outlet to ensure it is consistent and unobstructed.
- To Stop Operation: Disconnect the power plug from the electrical outlet.

5. Maintenance
Regular maintenance will prolong the life and efficiency of your pump:
- Disconnect Power: Always unplug the pump from the power source before performing any maintenance.
- Clean Intake Screen: Periodically check and clean the intake screen to remove any accumulated debris, such as dirt, algae, or sediment, which can reduce flow.
- Clean Impeller: If flow is significantly reduced, the impeller may be clogged. Carefully disassemble the pump (refer to diagrams if available, or gently pry open the intake cover) and clean the impeller and its housing. Rinse with clean water.
- Inspect Power Cord: Regularly inspect the power cord for any cuts, fraying, or damage. Do not use the pump if the cord is damaged.
- Storage: If storing the pump for an extended period, clean it thoroughly, dry it completely, and store it in a dry, frost-free location.
