With a strong 210 GPH flow rate, it provides excellent water circulation and maintains optimal water clarity for freshwater aquariums. Featuring a 3-stage filtration system, this canister filter effectively removes debris, odors, and harmful substances while supporting beneficial bacteria growth. It includes filter pads and allows additional filtration media such as activated carbon, ceramic rings, or bio balls for enhanced performance. The HW-604B combines power with quiet operation, making it ideal for home or office use. Its user-friendly design ensures quick setup and easy maintenance, making it suitable for both beginner and experienced aquarium hobbyists.

Safety Information

• Always unplug the filter from the power outlet before performing any maintenance, cleaning, or when handling the unit.
• Ensure your hands are dry when plugging or unplugging the unit to prevent electrical shock.
• Do not operate the filter if the power cord or plug is damaged. Contact qualified personnel for repair.
• The filter is designed for indoor use only and should not be exposed to water splashes or rain.
• Position the filter below the aquarium water level to ensure proper water flow and prevent dry running.
• Keep out of reach of children and pets.
• Do not run the filter dry. Always ensure the canister is filled with water before powering on.

Package Contents

Before beginning installation, please verify that all components are present in the package:

• SunSun HW-604B Canister Filter Unit
• Inlet and Outlet Hoses
• Intake Tube with Strainer
• Output Nozzle (Spray Bar or Duckbill)
• Filter Pads (Dense, Middle, Sparse)
• Water Filter Plates
• Suction Cups and Clips for Hose Installation
• Accessory Kit (various connectors and adapters)

Setup Instructions

1. Unbox and Check Parts: Carefully remove all components from the packaging. Confirm that all parts listed in the "Package Contents" section are present and undamaged.
2. Rinse Filter Media: Rinse all filter pads (dense, middle, sparse) and any additional media (if using) thoroughly with clean water or dechlorinated aquarium water. Do not use tap water directly on biological media as chlorine can harm beneficial bacteria.
3. Load Filter Media: Place the rinsed filter pads and water filter plates inside the canister trays in the correct order (typically coarse to fine filtration). Refer to the diagram below for the recommended layering. Optional: Add ceramic rings, activated carbon, or bio balls to improve filtration in designated media baskets.



4. Connect Hoses: Attach the inlet and outlet hoses securely to the canister's valve assembly. Install the intake tube with strainer and the output nozzle (e.g., spray bar) inside the aquarium using the provided suction cups and clips. Ensure all connections are tight to prevent leaks.



5. Position the Filter: Place the canister filter below the aquarium water level. This allows gravity to assist with water flow and ensures proper priming.
6. Fill with Water (Priming): Open the inlet valve. Fill the canister completely with water to begin siphon flow. Ensure the hoses are also filled to reduce trapped air. Some models may have a priming button; if so, use it to pump water into the canister until it is full.
7. Start the Filter: Once the canister is full and all connections are secure, plug the unit into a grounded power outlet. Water should begin circulating through the system.
8. Check for Leaks and Flow: Immediately inspect all connections for any leaks. Observe the water flow from the output nozzle to ensure it is consistent and strong. Adjust hose placement or connections if needed.

Operating Instructions

Once properly set up and primed, the SunSun HW-604B filter is designed for continuous operation to maintain water quality in your aquarium. Ensure the filter remains plugged in and powered on at all times, except during maintenance.

• Continuous Filtration: The filter should run 24/7 to provide consistent mechanical, biological, and chemical filtration for your aquarium.
• Flow Adjustment: If your model includes flow control valves, you can adjust the water flow rate as needed for your specific aquarium inhabitants and plant requirements.



• Monitoring: Regularly observe the water clarity and the filter's performance. A decrease in flow or unusual noises may indicate a need for maintenance.

Maintenance Guidelines

Regular maintenance is crucial for the optimal performance and longevity of your SunSun HW-604B filter.

1. Cleaning Frequency: Clean the filter every 2 to 4 weeks. The exact frequency depends on your tank size, bio-load, and the amount of debris accumulated.
2. Filter Media Care:
   • Rinse mechanical filter pads (dense, middle, sparse) using old aquarium water during a water change. This preserves beneficial bacteria.
   • Do not use tap water to rinse biological media (e.g., ceramic rings, bio balls) as chlorine can kill beneficial bacteria essential for nitrogen cycling.
3. Media Replacement:
   • Replace chemical filtration media, such as activated carbon, every 3 to 4 weeks if used, as its effectiveness diminishes over time.
   • Mechanical filter pads may need replacement when they become too worn or clogged to clean effectively.
4. Hose Maintenance: Inspect and clean hoses regularly to prevent algae and debris buildup, which can restrict water flow and reduce filter efficiency.
5. Impeller Care: Periodically check the impeller (the rotating part of the pump) for debris, such as plant matter or snail shells. Gently clean it to maintain optimal performance and prevent unusual noises.
6. General Recommendations:
   • Perform regular water changes to support overall aquarium health, complementing the filter's function.
   • Always ensure the canister is filled with water before powering on the unit to prevent damage from dry running.
