4. Setup
4.1 Before Installation
- Unpack the pump and inspect it for any damage.
- Verify that your power supply provides a stable DC 12V output. An incompatible power supply can damage the pump.
- Ensure the area where the pump will be placed is clean and free of debris.
4.2 Installation Steps
- Attach Suction Cups: If not already attached, place the suction cups onto the bottom of the pump for secure mounting.
- Position the Pump: Place the pump in the desired location, ensuring it is fully submerged in water. The suction cups can be used to secure it to a smooth surface like glass.
- Connect Water Pipe: Attach a water pipe or a fitted device to the pump's outlet nozzle. Ensure the connection is secure and watertight to prevent leaks and maximize lift height.
- Connect Power: Plug the pump's DC connector into a compatible DC 12V power supply.
- Test Operation: Once connected, the pump should begin operating. Observe for proper water flow and check for any leaks.

5. Operation
- The pump is designed for continuous operation when fully submerged in fresh water.
- Ensure the water level is always above the pump's intake to prevent dry running, which can damage the motor.
- Monitor the water flow to ensure it meets your requirements. The maximum lift height is achieved when the water pipe is securely connected to the nozzle.
- The pump operates quietly, but any unusual noises may indicate a blockage or malfunction.
6. Maintenance
Regular maintenance is crucial for the longevity and efficient operation of your pump.
- Regular Cleaning: Periodically remove the pump from the water and clean any accumulated debris from the intake screen and impeller area. This prevents clogging and maintains flow rate.
- Check for Blockages: Inspect the outlet nozzle and connected tubing for any blockages that might restrict water flow.
- Inspect Power Cord: Regularly check the power cord for any signs of damage or wear. Do not use the pump if the cord is damaged.
- Avoid Dry Running: Always ensure the pump is submerged in water during operation. Dry running can cause overheating and permanent damage.
- Storage: If storing the pump for an extended period, clean it thoroughly, dry it, and store it in a cool, dry place.
