4. Setup Instructions

4.1. Filter Media Installation

The HW-505A utilizes a 4-stage filtration system. Arrange the filter media in the baskets as follows, from bottom to top:

1. First Stage (Bottom Basket): Ceramic Rings for biological filtration, providing a large surface area for beneficial bacteria.
2. Second Stage: White Filter Floss for mechanical filtration, removing large particles.
3. Third Stage: Bio Balls for biological filtration, supporting beneficial bacteria and biological purification.
4. Fourth Stage (Top Basket): 4 cm Filter Sponge for mechanical filtration, trapping finer debris.

4.2. Filter Placement

Place the filter unit on a stable surface next to or below your aquarium. The filter must be positioned lower than the aquarium water level for proper operation.

4.3. Hose and Pipe Connection

1. Connect the inlet and outlet hoses to the corresponding ports on the filter head. Ensure a tight fit.
2. Assemble the inlet pipe (with strainer) and outlet pipe (with spray bar) components.
3. Attach the inlet pipe to one end of the inlet hose and the outlet pipe to one end of the outlet hose.
4. Secure the inlet and outlet pipes inside the aquarium using the provided suction cups and clips. The inlet pipe should be placed near the bottom of the aquarium, and the outlet spray bar near the water surface for optimal water circulation and oxygenation.
5. Install the submersible pump inside the aquarium, ensuring it is fully submerged. Connect the pump's outlet to the filter's inlet hose.

4.4. Priming the Filter

Before starting, the filter needs to be filled with water. This model uses an external pump, so priming is simpler:

1. Ensure all hoses are securely connected and the filter head is properly sealed.
2. Place the submersible pump in the aquarium.
3. The pump will push water into the filter. Once water flows out of the spray bar, the system is primed.

4.5. Power Connection

Once the filter is primed and all connections are secure, plug the power cord into a grounded electrical outlet. The filter will begin operating.

5. Operating Instructions

Once plugged in, the SunSun HW-505A filter will immediately start circulating and filtering your aquarium water. The filter is designed for continuous operation.

• Monitoring: Regularly check the water flow from the spray bar. A reduced flow may indicate clogged filter media or hoses, requiring maintenance.
• Quiet Operation: The filter is designed for quiet performance, typically between 50-70dB. If unusual noises occur, check for air in the system or obstructions in the pump impeller.

6. Maintenance

Regular maintenance is crucial for the optimal performance and longevity of your filter and the health of your aquarium inhabitants.

6.1. Cleaning Schedule

• Weekly: Check water flow and visually inspect hoses for blockages.
• Monthly (or as needed): Clean or replace mechanical filter media (filter floss, sponge). Rinse biological media (ceramic rings, bio balls) gently with old aquarium water to preserve beneficial bacteria.
• Every 3-6 Months: Thoroughly clean the filter canister, hoses, and pump impeller.

6.2. Cleaning Procedure

1. Disconnect Power: Unplug the filter and pump from the electrical outlet.
2. Disconnect Hoses: Close any valves on the hoses (if present) and disconnect them from the filter head.
3. Open Filter: Release the clamps on the filter head and carefully lift it off the canister.
4. Clean Media: Remove filter baskets. Rinse mechanical media (sponges, floss) under tap water until clean, or replace if heavily soiled. Gently rinse biological media (ceramic rings, bio balls) in a bucket of old aquarium water to avoid killing beneficial bacteria.
5. Clean Canister and Head: Rinse the filter canister and head with tap water. Use a brush to remove any stubborn debris.
6. Clean Pump: Disassemble the submersible pump and clean the impeller and housing. Remove any debris or mineral buildup.
7. Reassemble: Reassemble the filter in reverse order, ensuring all O-rings are properly seated and lubricated (if necessary) to prevent leaks.
8. Restart: Reconnect hoses, prime the filter as described in Section 4.4, and plug in the power.
