Do not use the pump with flammable materials, chemicals or acidic liquids.2. Please clean the water outlet and water pipe of the pump in time to see if they are clogged with dirt. Please clean the water pump in time.3. Please make sure that the power cord of the pump is lower than the power cord socket and forms a drip ring. This will prevent the water from flowing into the power outlet along the power cord.4. Do not allow the pump to run in a dry (no water) state to avoid affecting its life.5. Do not operate the pump when the water temperature is above 35.6. Warning: Disconnect the power supply before performing any operation and maintenance.7. Do not use the pump for other than the specified purpose
