The filter head is typically black, with various colored accents for controls (e.g., red, blue, white, as seen on the complete filter unit).
Installation (Replacement)
- Preparation: Disconnect the main filter unit from the power supply. Close all inlet and outlet valves to prevent water spillage.
- Remove Old Filter Head: Carefully detach the hoses from the existing filter head. Unclip or unlock the clamps securing the filter head to the filter canister. Lift the old filter head off the canister.
- Inspect Canister: Clean the rim of the filter canister and ensure the sealing gasket is free from debris.
- Install New Filter Head: Place the new SunSun HW-704B filter head onto the filter canister, aligning it correctly. Ensure the sealing gasket is properly seated between the head and the canister.
- Secure Filter Head: Fasten the clamps securely around the filter head and canister to create a watertight seal.
- Reconnect Hoses: Reattach the inlet and outlet hoses to their respective connections on the new filter head. Ensure hose clamps are tightened.
- Priming (if necessary): Follow the instructions for your specific HW-704B filter model to prime the system, typically by using a priming button or manually filling the canister.
- Power On: Open the inlet and outlet valves. Plug the filter unit back into the power supply. Check for leaks immediately.
Note: For detailed instructions on priming and specific hose connections, refer to the original manual of your SunSun HW-704B external filter.
Operation
Once the filter head is correctly installed and the system is primed, the filter will begin circulating and filtering water. The filter head contains the pump mechanism that drives the water flow. Ensure the water flow is consistent and there are no air bubbles trapped in the system.
- Flow Control: Some HW-704B models may have flow control levers on the filter head or valve block. Adjust these as needed for your aquarium's requirements.
- UV Lamp (if applicable): If your HW-704B model includes a UV sterilizer integrated into the filter head, ensure it is functioning. The UV lamp helps control algae and pathogens.
Maintenance
Regular maintenance of the filter head is crucial for optimal performance and longevity of your SunSun HW-704B filter.
- Impeller Cleaning: Periodically (e.g., monthly or bi-monthly, depending on usage and water conditions), disconnect power and remove the impeller cover on the filter head. Clean the impeller and its chamber thoroughly to remove any debris, algae, or mineral buildup.
- Gasket Inspection: Inspect the main sealing gasket between the filter head and the canister during each maintenance cycle. Replace if it shows signs of wear, cracking, or compression to prevent leaks.
- Hose Connections: Check hose connections for tightness and signs of wear. Clean any buildup inside the hose adapters.
- UV Lamp Replacement (if applicable): If your model has a UV lamp, replace it according to the manufacturer's recommendations (typically every 6-12 months) to maintain its effectiveness.
