- Ensure the voltage and frequency of your power supply match the pump's specifications (220-240V, 50Hz).
3. Package Contents
Upon opening the package, please verify that all components are present and undamaged. The typical package includes:
- Submersible Pump Unit
- Extension Tube(s)
- Air Intake Tube with Air Regulator
- Filter Basket/Sponge
- Suction Cups for Mounting
- Power Adapter Plug (EU, UK, or AU depending on region)


4. Setup Instructions
- Assemble the Pump: Attach the extension tube and filter basket to the main pump unit. If aeration is desired, connect the air intake tube to the designated oxygen inlet on the pump.
- Positioning: Place the assembled pump inside your aquarium, ensuring it is fully submerged in water. Use the integrated suction cups on the fixed base to securely attach the pump to the aquarium wall.
- Aeration Setup (Optional): If using the aeration function, ensure the air intake tube's open end is above the water surface. The air regulator can be adjusted to control the amount of air bubbles.
- Power Connection: Once the pump is securely installed and fully submerged, connect the power plug to a suitable 220-240V, 50Hz power outlet.


5. Operating Instructions
Once properly installed and connected to power, the pump will begin operating, performing its three-in-one functions:
- Water Pumping: Circulates water throughout the aquarium.
- Filtration: The filter basket removes debris and impurities from the water.
- Aeration: If the air intake tube is connected, the pump will draw air into the water, providing essential oxygen for aquatic life. Adjust the air regulator for desired bubble intensity.
The pump is designed for quiet operation, ensuring minimal noise disturbance.



6. Maintenance
Regular maintenance ensures optimal performance and longevity of your pump.
- Disconnect Power: Always unplug the pump from the power outlet before any maintenance.
- Clean Filter: Remove the filter basket and rinse the filter sponge thoroughly under clean water. Replace if heavily soiled or damaged.
- Clean Impeller: Carefully remove the impeller cover and the impeller itself. Clean any debris or buildup from the impeller and its housing.
- Inspect Shaft Core: Check the shaft core for wear or damage. Note that R375M and R119M models use a ceramic shaft, while R338M and R362M models use a stainless steel shaft core.
- Reassemble: Reassemble all components in reverse order, ensuring they are securely fitted.


7. Troubleshooting
- Pump not starting: Check if the power plug is securely connected and the outlet is functioning. Ensure the pump is fully submerged.
- Reduced water flow or aeration: Disconnect power and check for blockages in the filter, impeller, or tubing. Clean as per maintenance instructions.
- Unusual noise: Disconnect power and check the impeller for any foreign objects or damage. Ensure all components are correctly assembled.
