4. Setup and Installation
Follow these steps to install the new filters:
- Rinse Filters: Before first use, thoroughly rinse the activated carbon filter and the filter sponge under running water for several minutes. This removes any loose carbon dust and prepares them for optimal filtration.
- Disassemble Fountain: Turn off and unplug your APD APETDOLA FS20 water fountain. Disassemble the top tray and remove the old filter and sponge.

- Reassemble Fountain: Reassemble the fountain components, ensuring all parts are correctly aligned.
- Refill Water: Fill the fountain with fresh water to the appropriate level.
