Package Included:
6* DC 3-5V Micro Submersible Mini Water Pump
Notice:
1. The pump is a DC pump, 3V pump with DC 3-4.5V power supply (CAN NOT be used directly with 220V AC voltage);
2. It is recommended to use 3-5V as power source, battery, power bank, USB cable, mobile phone charger, etc.
3. When diving the water pump into the water, the water level should higher than the pump.Dry run may damage the motor due to heating and it will also produce noise.
4. Ground use need to allow water to flow into the pump (non self priming pump), the installation of water level higher than the pump.
5. To keep the water clean, so as not to block the pump rotor. the pump should be cleaned regularly to keep the pump clean.
6. There may be 1-3mm of size deviation due to manual measurement.
7. There may be a little color difference due to display pixel and light.

Tips:
1. Common Troubleshooting: The pump flow is reduced or no water. (The pump chamber can be disassembled for cleaning)
2. Common Troubleshooting: When the pump does not run water. (There is air in the pump or in the pipeline.)
