2. Safety Information

Adherence to the following safety guidelines is crucial for preventing injury and damage to the pump. Please read and understand all warnings before operating the device.

• The operating temperature range: 0-115℉ (approximately -17.8℃ to 46.1℃). Do not operate outside this range.
• Before purchasing, verify that the water level and layout of your tank or system are compatible with the pump's power. An imbalance (e.g., too little water with high motor power) can lead to loud noises from splashing water. Different pumps are suited for different water tank sizes and types.
• Prohibit no-load running: Always ensure the pump is fully submerged in water before connecting it to a power supply. Operating the pump in air for extended periods will shorten its lifespan and can cause loud noises.
• When performing maintenance or changing water, always disconnect the power supply to the pump first.
• If the pump suddenly stops working or begins to make unusual noises, it may be due to debris blockage. Refer to the Maintenance section for cleaning instructions. Regular cleaning (approximately every two months) is recommended. Applying a small amount of olive oil to the rotor after cleaning can help maintain smooth operation.
• A small amount of residual water may be present in the pump upon receipt. This is normal and results from professional water testing conducted by the manufacturer prior to shipment to ensure product quality.
• The maximum flow rate is 660 GPH (2500 L/H). Actual flow rates may vary due to factors such as insufficient power supply, incorrect frequency, or connection to water pipes. If water is sprayed out of the container, the effective flow rate will also be less than the maximum.
• If using this water pump for sensitive fish or plants, ensure to thoroughly clean any assembly oil off the impeller and inside the pump before installation.

6. Maintenance

Regular maintenance is essential to ensure the longevity and efficient performance of your KEDSUM water pump. It is recommended to clean the pump approximately every two months, or more frequently if operating in environments with high debris.

2. Remove from Water: Carefully remove the pump from its submerged location.
3. Disassemble for Cleaning:
   • Part 1: Filter Cover: Remove the filter cover (typically the front intake grill) by gently prying or unsnapping it. Clean any accumulated debris from the cover.
   • Part 2: Outlet Nozzle: Detach the outlet nozzle and clean any blockages.
   • Part 3: Motor/Impeller: Access the impeller chamber, usually by removing a cover near the outlet. Carefully remove the impeller. Clean the impeller and its housing thoroughly to remove any slime, algae, or debris. A small brush can be helpful.
4. Lubrication (Optional): After cleaning, you may apply a small amount of olive oil to the rotor (impeller shaft) to ensure smooth operation upon reassembly.
5. Reassemble and Test: Reassemble all parts in reverse order. Ensure all components are securely fitted. Submerge the pump completely in water and then reconnect power to test its operation.
