Setup Instructions
Follow these steps to assemble your Casfuy PWS-154 Pet Water Fountain:
- Clean Components: Before first use, thoroughly clean all parts of the fountain (stainless steel tank, top cover, pump, filter case, metal faucet pipe) with water and mild soap. Rinse thoroughly.
- Assemble Filter: Place the filter sponge into the filter case. Insert the activated carbon filter into the filter case on top of the sponge.
- Install Pump: Place the water pump into the pump holder at the bottom of the stainless steel water tank. Ensure the power cord is routed through the designated groove to prevent pinching.
- Place Filter: Position the assembled filter case onto the pump, ensuring it sits securely.
- Add Water: Fill the stainless steel tank with clean water. Ensure the water level is above the minimum mark (approximately 30% full) and below the maximum fill line. The pump must be fully submerged.
- Attach Top Cover and Faucet: Place the stainless steel top cover onto the tank. Insert the metal faucet pipe into the opening on the top cover, ensuring it connects securely to the pump outlet.
- Connect Power: Connect the power adapter to the fountain's USB interface and then plug the adapter into a standard wall outlet.

Operating Instructions
Once assembled and powered, the fountain will begin to operate. The Casfuy PWS-154 offers dual water flow modes:
- Flowing Stream Mode: Water flows from the metal faucet pipe, mimicking a tap, which can attract pets to drink.
- Bubbler Mode: By removing the metal faucet pipe, water bubbles up from the center of the top cover, creating a gentle, interactive drinking experience.

Water Level Monitoring: The fountain features an oversized circular window with a built-in LED light, allowing you to easily monitor the water level, even in low light conditions. Always ensure the water level is sufficient to keep the pump submerged.
