3. Opsætning og installation
3.1 Udpakning og komponentidentifikation
Carefully unpack all components. Refer to the 'What's Included' diagram to ensure all parts are present.

Figure 3.1: Included Components. This diagram illustrates all parts supplied with the Fluval FX4, including the main unit, media baskets, biofoam, carbon foam, pouches, biomax, flow clamps, metal clamps, output nozzle, intake, and hoses.
3.2 Medieindlæsning
The FX4 features a 4-stage filtration system with removable media baskets. These baskets are designed to prevent water bypass, maximizing filtration efficiency. Each basket is lined with a foam insert for mechanical pre-filtering. Arrange your chosen mechanical, chemical, and biological media within the baskets. The basket-in-basket design allows for flexible media combinations.

3.3 Placement and Hose Connection
The FX4 filter is compact, standing 16.5 inches (42 cm) tall, allowing it to fit under most standard aquarium cabinets. Position the filter on a stable, level surface below the aquarium. Connect the intake and output hoses using the Aquastop Click-Fit Valves, ensuring a leak-free and secure connection. The versatile intake features a telescopic stem and anti-clog strainer, while twin output nozzles allow for customized water currents.

4. Betjening
4.1 Initial Start-up and Self-Priming
After assembly and hose connection, simply add water to your aquarium and plug in the filter. The patented Smart Pump Technology will automatically initiate the self-priming process. This advanced microchip technology continuously monitors and optimizes pump performance, ensuring powerful output and energy efficiency. It also manages the filter's self-starting feature and evacuates any trapped air.
4.2 Smart Pump Technology
The Smart Pump Technology employs an electronic circuit board that constantly monitors the pump. Impeller speed and force are measured to maintain optimal performance and energy efficiency. On a 12-hour cycle, the pump will pause briefly to allow trapped air to escape, ensuring consistent and efficient filtration. This contributes to quiet operation and reduced noise.

Figure 4.1: Smart Pump Technology. This diagram visually represents the microchip technology that monitors and optimizes pump performance, enabling auto-start, self-priming, quiet operation, and energy efficiency.
5. Vedligeholdelse
5.1 Routine Cleaning of Filter Media
Regular cleaning of filter media is essential for maintaining optimal water quality. The instant-release T-handles allow for quick and easy removal of media baskets. Clean the foam inserts and other reusable media in old aquarium water to preserve beneficial bacteria. Replace chemical media as recommended by the manufacturer.
5.2 Vandskift
The FX4 features a multi-functional utility valve at its base, enabling seamless water changes. This valve allows you to drain water from the canister and refill directly, simplifying the process and reducing effort. Convenient lid-mounted hosing clips provide clean storage for hoses when not in use.

5.3 Impeller and O-Ring Maintenance
Periodically inspect and clean the impeller to ensure consistent flow. If the impeller wears out, it can be easily replaced. Regularly lubricate the O-rings to maintain a proper seal and prevent leaks. Replace O-rings if they show signs of wear or damage.
6. Fejlfinding
- Reduceret flow: Check if filter media is clogged. Clean or replace media as necessary. Ensure hoses are not kinked or obstructed. Verify the impeller is clean and functioning correctly.
- Overdreven støj: Ensure the filter is placed on a level surface. Check for trapped air; the Smart Pump Technology will auto-evacuate air every 12 hours, but manual intervention might be needed if noise persists. Inspect the impeller for damage or debris. Rubber feet are designed to reduce vibration.
- Lækager: Ensure all hose connections are secure and Aquastop valves are properly seated. Check the main O-ring seal on the filter head and lubricate or replace if necessary.
- Filteret starter ikke: Verify the power connection. Ensure the unit is properly primed (Smart Pump should handle this automatically). Check for any blockages in the impeller chamber.
