3. Setup Instructions
Follow these steps to assemble and set up your Invengo Cat Water Fountain:
- Prepare the Filter: Submerge the filter element in clean water for 5-10 minutes to ensure it is thoroughly soaked before first use.
- Install the Pump and Sponge: Secure the water pump to the designated holder on the lid. Place the black circular sponge over the outer perimeter of the water pump, ensuring it does not obstruct the indicator light.
- Insert the Filter: Open the filter chamber on the lid and insert the soaked filter cartridge. Close the chamber securely.
- Attach the Faucet: Install the water outlet faucet onto the lid. This allows for the 'faucet flow' mode.
- Fill the Reservoir: Fill the stainless steel reservoir with clean water up to the 'MAX' line. The transparent water level window on the front allows for easy monitoring.
- Secure the Lid: Place the assembled lid onto the reservoir, ensuring it fits snugly.
- Connect Power: Connect the USB power cord to the pump and then to the adapter. Plug the adapter into a power outlet. The fountain will begin operating.

4. Operating Instructions
The Invengo SSPF-S4 fountain offers two distinct water flow modes to cater to your pet's preferences:
- Faucet Flow: With the faucet attachment installed, water flows from the faucet, mimicking a running tap. This mode is often preferred by cats.
- Fountain Flow: Without the faucet attachment, water bubbles up gently from the center, creating a natural spring-like effect.
The fountain operates continuously when plugged in. The ultra-quiet pump ensures minimal noise (below 20dB), providing a peaceful drinking environment for your pets without disturbing your home.

5. Maintenance
Regular cleaning and maintenance are crucial for the longevity of your fountain and the health of your pets:
- Daily: Check the water level using the transparent window and refill as needed.
- Weekly: Disassemble the fountain and clean all components (reservoir, lid, pump, faucet) with mild soap and water. Rinse thoroughly. The quick-detach design allows for easy hand washing.
- Filter Replacement: Replace the filter element every 2-4 weeks, or more frequently if you have multiple pets or notice reduced water flow/quality. Replace the pre-filter sponge every 2-4 weeks.
- Pump Cleaning: Periodically clean the pump to prevent mineral buildup and ensure optimal performance. Refer to the pump's specific cleaning instructions.

6. Troubleshooting
If you encounter any issues with your Invengo Cat Water Fountain, please refer to the following common solutions:
