1. Introducció
The SunSun Biological Filter CBF-200A with an integrated 9W UV unit is designed to provide effective biological and mechanical filtration for garden ponds. This system helps maintain clear and healthy pond water by removing suspended particles and reducing algae growth without the need for harsh chemicals. It is suitable for ponds up to 8000 liters without fish or 4000 liters with fish.

2. Instruccions de seguretat
Si us plau, llegiu i comprengui totes les instruccions de seguretat abans de fer servir aquest dispositiu. Si no segueix aquestes instruccions, es poden produir descàrregues elèctriques, incendis o lesions greus.
- Always disconnect the power supply before performing any maintenance, cleaning, or installation work.
- Do not operate the filter if any part is damaged, especially the power cord or UV lamp habitatge.
- Ensure the electrical outlet is properly grounded and protected by a Residual Current Device (RCD) with a tripping current not exceeding 30 mA.
- Mantingueu el dispositiu fora de l'abast dels nens i les mascotes.
- No submergiu els components elèctrics en aigua.
- La UV-C lamp emits harmful radiation. Never look directly at the illuminated UV-C lamp. Replace the UV-C lamp only when the device is disconnected from the power supply.
- Install the filter on a stable, level surface to prevent tipping and ensure proper water flow.

Mitjans de filtració

Image 3.2: Internal filtration materials.
- Filter Sponges: Two specific sponges (blue and yellow) provide mechanical filtration, trapping fine and coarse particles.
- Japanese Mat: A polyester monofilament mat offers an ideal colonization surface for nitrifying bacteria, promoting biological purification.
- Bio-balls: Approximately 15 bio-balls provide additional surface area for beneficial bacteria to thrive, enhancing biological filtration.
4. Configuració i instal·lació
The filter system is designed for simple and autonomous operation, requiring a standard pond pump and hose (not included).
4.1 Col·locació
- Place the filter on a firm, level surface next to your pond. It must be stable and not prone to tipping.
- Ensure the filter is positioned lower than the pond's water level to allow for gravity-fed return flow, or ensure your pump is capable of pushing water to the desired outlet height.
4.2 Connexions
- Connexió d'entrada: Connect a suitable pond pump (not included) to the filter's inlet port. Ensure a tight, leak-free connection.
- Connexió de presa: Connect a hose to the filter's outlet port to return filtered water to the pond.
- UV Lamp Connexió: Ensure the UV lamp is correctly seated within its housing and the electrical connection is secure. The UV lamp is pre-installed but verify its position.

5. Instruccions de funcionament
5.1 Inici inicial
- After all connections are secure and the filter is properly placed, turn on the pond pump.
- Allow water to fill the filter chamber. Check for any leaks.
- Once water is flowing smoothly through the outlet, connect the filter's power supply to activate the UV unit.
5.2 Seguiment

Image 5.1: Efficient pond filter flow diagram.
- Turbidimeter: The integrated orange float (turbidimeter) indicates when the filter media requires cleaning. When the float rises, it signifies increased resistance due to accumulated dirt.
- Termòmetre: The built-in thermometer displays the water temperature, ranging from 8°C to 40°C, allowing you to monitor pond conditions.
- Caudal: The system supports a maximum flow rate of 6000 liters per hour.

6. Manteniment
Regular maintenance ensures optimal performance and longevity of your filter system.
6.1 Cleaning Filter Media
Clean the filter sponges and Japanese mat when the turbidimeter indicates a need for cleaning (orange float rises).
- Desconnecteu l'alimentació: Always disconnect the filter and pump from the power supply before cleaning.
- Open Filter: Carefully open the filter lid.
- Remove Sponges: Remove the filter sponges one by one. Important: Do not clean all filter sponges at once. Clean only one or two at a time to preserve beneficial bacteria colonies.
- Rinse Sponges: Squeeze and rinse the removed sponges thoroughly with pond water (not tap water, as chlorine can kill beneficial bacteria).
- Drain Dirty Water: Open the drainage port to allow dirty water to drain from the filter housing.
- Torneu a muntar: Place the cleaned sponges back into the filter, close the lid securely, and reconnect power.

6.2 UV Lamp Substitució
La UV-C lamp has a limited lifespan and should be replaced approximately every 8000 operating hours or annually, even if it still appears to be working, as its germicidal effectiveness diminishes over time.
- Desconnecteu l'alimentació: Absolutely ensure the filter is disconnected from the power supply.
- Access UV Unit: Follow the instructions in the exploded view (Image 3.1) to safely access the UV-C lamp habitatge.
- Elimina la L antigaamp: Carefully remove the old UV-C lamp and quartz glass tube. Handle the new lamp by its base to avoid touching the glass.
- Instal·la la nova Lamp: Insert the new 9W UV-C lamp and reassemble the unit, ensuring all seals and O-rings are correctly seated to prevent water ingress.
- Torneu a connectar l'alimentació: Once fully reassembled, reconnect the power supply.

7. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| Water remains cloudy/green | Clogged filter media; UV lamp ineffective or faulty; Pond too large for filter capacity; Insufficient pump flow. | Clean filter sponges and mat. Check/replace UV lamp. Verify pond size against filter capacity. Ensure pump is providing adequate flow. |
| Reduced water flow from outlet | Clogged filter media; Blockage in inlet/outlet hoses; Pump issue. | Clean filter media. Check hoses for blockages. Inspect pond pump for proper operation. |
| UV lamp no il·lumina | Lamp faulty; Electrical connection loose; UV ballast failure. | Disconnect power, check lamp connection. Replace UV lamp. If still not working, contact support for ballast inspection. |
| Water leaking from filter | Lid not properly sealed; Damaged O-rings; Loose hose connections. | Ensure lid is securely fastened. Check O-rings for damage and proper seating. Tighten all hose connections. |
