Precautions for pumps

1.To prevent electric shock accidents, corresponding security measures such as leakage circuit breakers or electric shock protectors must be installed, and reliable grounding must be carried out.
2. The operating voltage range of the pump must be between+5% and -12% of the rated voltage, otherwise it will shorten the service life of the motor or burn it out. If the electric pump is used far from the power supply, the power supply transmission line should be appropriately thickened, otherwise the voltage will drop and it will not be able to operate.
3. Turn on the power switch and let the pump idle for about 2 minutes. Check if it starts and runs normally, and if the steering is correct.
4. Fix the pump body, use steel pipes or rubber hoses (not too soft to avoid flattening), connect the water inlet and bottom valve. The bottom valve must be placed perpendicular to the horizontal plane, at least 30cm away from the bottom of the water, to avoid suction of sediment.
5. Before using the centrifugal pump for clean water and the automatic suction and cleaning pump for the first time, the water storage tank should be filled with water. After being powered on for several tens of seconds, it cannot automatically discharge water, and there is no need to fill water for future use.
6. Before using the self priming water pump and automatic self priming water pump pipes for the first time, the water storage tank should be filled with water. After being powered on for several seconds, the water cannot automatically flow out, and there is no need to fill it in for future use.
