Please follow the instructions below before using the pump: 1. Check the voltage and power of the pump before powering it on. 2. Cut off the power before installing, removing, or placing the pump in water to prevent air from getting trapped and causing a blockage. 3. The pump is suitable for use in water or other clean liquids without particles or impurities, but not suitable for viscous or acid-base liquids. 4. Do not dry burn the pump as it may cause damage. 5. To eliminate air in the pump impeller and pipes, switch the power on and off repeatedly several times. 6. When using the pump in a high-temperature environment (100°C), it should only be installed using the non-submersible method.
