Please check that all items are present and in good condition:

4. Setup and Installation

  1. Unpack and Inspect: Carefully unpack all components. Inspect the UV sterilizer unit, power adapter, and cord for any signs of damage. Do not proceed with installation if any damage is found.
  2. Attach Mounting Suction Cups: Securely attach the provided suction cups to the body of the UV sterilizer unit. These will be used to fix the unit inside your aquarium or pond.
  3. Positioning: Submerge the UV sterilizer completely in your aquarium or pond. Place it in an area with good water circulation to ensure efficient water treatment. Avoid placing it directly in front of a strong filter outflow, which might reduce contact time.
  4. Secure the Unit: Press the suction cups firmly against the tank wall or bottom to secure the unit in place. Ensure it is stable and cannot float or move freely.
  5. Connect Power: Connect the power adapter to the sterilizer unit. Then, plug the power adapter into a suitable electrical outlet. It is highly recommended to use a separate power switch for the unit for added safety and convenience.
  6. Verify Submersion: Before powering on, double-check that the entire UV lamp and its housing are fully submerged in water. Operating the UV lamp out of water can cause overheating and damage, and expose users to harmful UV radiation.

5. Operating Instructions

Once the Sunsun AUV Series UV Sterilizer is properly installed and connected to power, it will begin operation. The UV light continuously treats the water that flows around it, inhibiting the growth of harmful microorganisms and preventing algae.

6. Maintenance

Regular maintenance is crucial for the optimal performance and longevity of your UV sterilizer.

  1. Power Disconnection: Always disconnect the power supply to the UV sterilizer before performing any maintenance or handling the unit.
  2. Cleaning the Quartz Sleeve:

    Over time, the transparent quartz sleeve that protects the UV lamp may accumulate algae, mineral deposits, or other debris. This buildup can reduce the effectiveness of the UV light.

    • Carefully remove the UV sterilizer unit from the water.
    • Gently wipe the exterior of the quartz sleeve with a soft, clean cloth to remove any buildup. For stubborn deposits, a mild vinegar solution can be used, followed by a thorough rinse with clean water.
    • Do not use abrasive cleaners or harsh chemicals, as these can scratch or damage the quartz sleeve.
  3. UV Lamp Replacement:

    The UV lamp has a finite lifespan, typically 6 to 12 months of continuous use, after which its germicidal effectiveness diminishes, even if it still appears to be glowing. It is recommended to replace the UV lamp annually.

    • Refer to your specific model (AUV-24W) to purchase the correct replacement UV lamp.
    • Carefully remove the old UV lamp from the unit, following the manufacturer's instructions (usually involves unscrewing an end cap and sliding out the lamp).
    • Handle the new lamp by its ceramic ends, avoiding direct contact with the glass, as oils from your skin can create hot spots and reduce lamp life.
    • Insert the new lamp and reassemble the unit securely.
    • Dispose of old UV lamps according to local regulations for hazardous waste.
  4. Housing and Cord Inspection: Periodically inspect the sterilizer's housing and power cord for any signs of cracks, damage, or wear. If any damage is observed, discontinue use immediately and replace the unit.
