Precautions:
1. This pump is centrifugal pump, it can't vent the air automatically, so it must be operated by submersible installation. (If outside water installation, you should make sure it is installed below the liquid surface)The water pump must be immersed in the water, or the horizontal plane on the day of pipeline connection must be lower than the water inlet nozzle of the water pump. The air in the water inlet chamber of the pump is discharged after water is injected, and the water pump can pump normally
2. When selecting the water pump, be sure to give the use environment: for example, continuous working time, water temperature, medium, etc. if the water pump power exceeds 24W, it is suitable to work continuously at the water temperature above 65 ℃ for a long time. Please be sure to communicate with professionals in order to select the most appropriate water pump model
3. The above current is the opening current of the water pump, that is, when the water pump is directly put into the water without any system, and the working current of the maximum electric pump connected to the system will be reduced to 70% - 85% of the maximum load current
4. The head of the pump is the maximum water delivery height, that is, the flow reaching the maximum head point is zero.
5. The flow of water pump is horizontal flow, that is, the flow of horizontal pumping.
6. The water pump cannot work without water for a long time.


Usage:
The water pump cable (red is positive, do not take the wrong) received a suitable power supply (the battery can be a battery, it can be a power converter), and then a good water pipe, then pump into the water, Can be used normally.
(Note: The DC brushless pump is a centrifugal pump, the pump water flow with the increase of the head decreases.No diving without self-priming function, prohibit no water free.)
Common Troubleshooting:
1.The pump flow is reduced or no water. (The pump chamber can be disassembled for cleaning).
2Tland use when the pump does not run water. (There is air in the pump or in the pipeline.)
