(The pump chamber can be disassembled for cleaning).2. When the pump does not run water. (There is air in the pump or in the pipeline.) Note:1.Do not take the wrong pump positive and negative.2.Prohibit not through the power converter will be connected directly to the 220V power supply pump.3.Is strictly prohibited for strong acidity, alkali and other damage to the pump medium.4.The pump is suitable for medium temperature 1 в„ѓ -60 в„ѓ.
