is 10w and suitable for a long time working under this condition

四.附加功能说明Additional function instructions

1

卡死保护

Jam protection

卡死的时候水泵停止工作

When jam it will Stop to protect itself

2

缺水/空转保护

Dry run protection

水泵缺水或者空转时水泵会循环的停转(4秒)运转(2秒),可定制保护策略

The pump will Stop(8S) and start(2s) repeatedly to protect itself(can be customized)

3

过压保护

Overloading protection

当电压不稳定或者其他原因导致超过水泵额定功率,水泵停止运行

When the voltage exceeds the rated power, the pump will stop

4

电源反接

Reverse protection

电源正负极接反,水泵停止运行,重新接后,正常工作

Wrong connection of the power supply(positive and negative), the water pump will stop running, and then re-connected, can work normally.

注意:本产品不具备自吸功能,因此在安装时,需要保证压盖型腔内具有足够的水,即安装时需要保证水泵中心位置低于水箱内液面,以保证水泵能够正常运行!

Notice: The pump is not self-priming pump. When install, please make sure there is enough water in pump gland. Meanwhile, the pump must be installed below the liquid level in the tank.

十.注意事项Notice

1.使用带有大于0.35mm的杂质和陶磁性颗粒的液体。                                 It is forbidden to use liquids with impurities greater than 0.35mm and ceramic or magnetic particles.

2.长时间不使用时,通电前最好先使用泵内有一定的液体。                                If it is not used for long time,make sure water goes inside the pump before power on.

3.通电前请先确认连接无误,否则可能产生故障。                                        If not used for long time, please make sure cord connection correctly.

4.严禁泵内无液体时长时间使用。                                                    Do not let pump dry run .

5.低温环境使用时,请确保使用液体不会出现结冰或者变得很粘稠。                        If use in low temperature environment, please make sure the water won’t be frozen or thick..

6.连接器的针脚处有水渍,请将水渍处理干净后再使用。                              Please check if there is water on connection plug, and clean it before us
