1. Introduction
The Anbull Bio Pressure Pond Filter is designed to maintain clear and healthy water in your pond. This system effectively removes suspended solids and organic matter, and includes an 11-watt UV-C lamp to improve water quality. It is suitable for ornamental ponds up to 1600 gallons and fish ponds up to 800 gallons. For optimal performance, this filter must be used in conjunction with a water pump.

2. Product Overview and Components
This pressurized biological pond filter integrates mechanical, biological, and UV filtration to ensure comprehensive water purification. It features multiple filter sponges and an integrated UV-C lamp.



3. Setup Instructions
Proper setup is crucial for the efficient operation of your pond filter. Ensure all connections are secure and the unit is placed correctly.
3.1 Connecting Hoses
The filter includes 9 adapters (3/4”, 1”, 5/4” each x3) to accommodate various water pipe sizes. Connect your water pump's outlet hose to the filter's water inlet. Connect the drainage outlet and sewage exit to appropriate return lines or disposal areas.
3.2 Placement
The robust design of the filter allows it to be placed next to the pond or partially buried to integrate seamlessly into your landscape. Ensure the filter is on a stable, level surface.


4. Operating Instructions
The filter is designed for straightforward operation with a simple function switch.
4.1 Function Switch
The function switch located on the top of the filter allows you to easily switch between two modes:
- Filter Mode: For continuous water filtration.
- Clean Mode: For backwashing and cleaning the filter sponges.
4.2 Cleaning Indicator
The filter is equipped with a cleaning indicator. When the orange part of this indicator floats up, it signals that the filter sponges require cleaning.

5. Maintenance
Regular maintenance ensures the longevity and effectiveness of your Anbull Bio Pressure Pond Filter.
5.1 Cleaning Filter Sponges (Backwash)
When the cleaning indicator shows that maintenance is needed, switch the function to 'Clean' mode. Use the crank handle to agitate and clean the filter sponges. This process backwashes the accumulated debris out through the sewage exit, without needing to open the filter unit.
5.2 Replacing Filter Sponges
Over time, filter sponges may need replacement. To replace them, unclamp the top of the filter unit and carefully lift the internal assembly. Remove the old sponges and insert new ones, ensuring they are correctly seated. Then, reassemble the filter, making sure the clamp is securely fastened.

5.3 Replacing the UV-C Lamp
The 11-watt UV-C lamp has a limited lifespan and will need to be replaced periodically to maintain its effectiveness in controlling algae. Refer to the specific instructions in your product manual for safe replacement procedures.

6. Troubleshooting
If your Anbull Bio Pressure Pond Filter is not operating as expected, consider the following common issues:
- No Power: Ensure the power cord is securely plugged into a functional outlet. Check your circuit breaker.
- Reduced Flow: This often indicates clogged filter sponges. Perform a backwash cycle using the crank handle. If flow remains low, inspect hoses for kinks or blockages.
- Cloudy Water: If water remains cloudy after cleaning, the UV-C lamp may need replacement, or the pond's biological balance might require adjustment. Ensure the UV-C lamp is functioning (check observation window).
- Leaks: Check all hose connections and ensure the main clamp securing the filter head is properly sealed.
For persistent issues, please contact Anbull customer support.
