Introduction
This manual provides instructions for the TRIXIE 24451 replacement filters, designed for use with the TRIXIE 24450 pet water fountain. Regular filter replacement is essential for maintaining water quality and the longevity of your fountain.
Product Overview
The TRIXIE 24451 replacement filter pack contains four individual filters. Each filter is designed to purify water, removing impurities and odors, ensuring fresh drinking water for your pet.

Initial Setup and Filter Installation
Before first use or after cleaning the fountain, install a new filter by following these steps:
- Rinse the new filter thoroughly under cold running water for several minutes to remove any loose carbon dust.
- Disassemble the TRIXIE 24450 water fountain according to its specific instructions.
- Locate the filter housing within the fountain.
- Insert the rinsed filter into the designated slot, ensuring it is seated correctly.
- Reassemble the fountain, ensuring all parts are securely in place.
- Fill the fountain with fresh water.

Operation
Once the filter is installed and the fountain is filled with water, plug in the fountain to begin operation. The filter will continuously purify the water as it circulates. Ensure the water level is always above the minimum mark to prevent pump damage.
Maintenance and Filter Replacement
For optimal water quality and fountain performance, replace the filter regularly. It is recommended to replace the filter every 2 to 4 weeks, or more frequently if multiple pets use the fountain or if the water appears dirty.
- Unplug the water fountain from the power outlet.
- Disassemble the fountain.
- Remove the old, used filter from its housing. Dispose of the old filter responsibly.
- Rinse a new TRIXIE 24451 filter under cold running water for several minutes.

- Clean the fountain components (pump, bowl, lid) thoroughly before reassembly.
- Reassemble the fountain and refill with fresh water.
- Plug the fountain back into the power outlet.

Troubleshooting
- Fountain not dispensing water: Check if the pump is clean and free of debris. Ensure the water level is sufficient. Verify the power connection.

- Unpleasant odor or taste in water: Replace the filter immediately. Clean the entire fountain thoroughly.
