5. Setup
- Unpack and Inspect: Carefully remove all components from the packaging. Inspect for any damage.
- Assemble Fountain Head (Optional): If using the fountain function, attach the desired fountain head to the top of the fountain pole. Insert the fountain pole into the pump's outlet. Ensure it is securely fitted.
- Connect Hose (Optional for Pumping): If using the pump for water circulation without a fountain, connect a suitable hose to the water outlet.
- Placement: Place the entire unit into your pond, ensuring it is fully submerged. The unit should rest on a stable, level surface at the bottom of the pond. Ensure the power cord is routed safely and securely, avoiding kinks or damage.
- Power Connection: Connect the UL certified power cord to a grounded electrical outlet. Ensure a drip loop is formed to prevent water from traveling along the cord to the outlet.
6. Operating Instructions
- Power On: Once submerged and connected, the unit will begin operating. The UV-C lamp will also activate. You can check the UV lamp's operation through the observation window.
- Adjust Fountain Height: If using the fountain, adjust the height of the fountain tube as desired.
- Adjust Water Flow: Use the tee adjuster to control the water flow rate for either the fountain or the pumping outlet. This allows you to customize the water display or circulation intensity.
- Monitoring: Regularly observe the pond water clarity. The UV-C lamp and filtration system work continuously to maintain water quality.

7. Maintenance

- Regular Cleaning of Filter Sponges: The filter sponges should be cleaned regularly, typically every 2-4 weeks depending on pond conditions.
- Unclip the safety buckles and open the unit cover.
- Remove the filter sponges and rinse them thoroughly with pond water (not tap water, to preserve beneficial bacteria).
- Clean the filter material box if necessary.
- Reassemble the unit, ensuring the cover is securely clipped.
For detailed instructions on disassembly and cleaning, refer to the product's instructional materials or manufacturer's website.

- Disconnect power.
- Open the unit and carefully remove the UV-C lamp housing.
- Replace the old lamp with a new 13W UV-C lamp. Handle new lamps by their ends to avoid touching the glass.
