Setup Instructions
Follow these steps to assemble and prepare your pet water fountain for use:
- Clean Components: Before first use, thoroughly clean all parts of the fountain (stainless steel tank, pump, faucet, filter case, and drinking basin) with water and mild soap. Rinse well.
- Install Filter Sponge: Place the filter sponge around the water pump.
- Assemble Pump and Filter: Insert the water pump into the designated slot in the filter case. Place the multi-layer filter (activated carbon, ion resin) into the filter case.
- Position Faucet: Attach the water faucet to the top stainless steel drinking basin.
- Assemble Fountain: Place the assembled drinking basin with the pump and filter onto the stainless steel water tank. Ensure all parts fit securely.
- Fill with Water: Fill the stainless steel tank with clean water. Ensure the water level is above 30% of the tank's capacity to prevent the pump from running dry. Do not overfill.
- Connect Power: Connect the power adapter to the fountain and then plug it into a standard electrical outlet.

Operating Instructions
Your Casfuy PWS-155 fountain is designed for continuous operation to provide fresh water for your pets.
- Power On: Once plugged in, the fountain will begin operating. The pump is designed for ultra-quiet performance, typically below 20dB.
- Water Flow Modes: The fountain offers two water flow modes:
- Faucet Mode: Mimics running tap water, which can encourage pets to drink more.
- Fountain Mode (Gentle Bubble): Provides a bubbling surface, promoting better posture and spinal health for pets while drinking.
- Water Level Monitoring: The fountain features a water level window with an LED light. Monitor this window to easily check the water supply. Refill the tank when the water level is low to prevent the pump from running dry.


Maintenance
Regular cleaning and filter replacement are crucial for maintaining water quality and the longevity of your fountain.
- Refill Often: Always keep the water level above 30% or full. The pump can fail if it runs dry.
- Clean Regularly: Clean the pump, water tank, drinking basin, and the filter case every 1-2 weeks. Before cleaning, carefully remove the filter and sponge. The 304 stainless steel components are rust-resistant and dishwasher safe.
- Replace Filter: Replace the multi-layer filter every 1-2 weeks when you clean your fountain. This ensures continuous multi-layer filtration, removing odors, chlorine, and softening water.
- Replace Sponge: Replace the filter sponge every 3-4 weeks, depending on the frequency of use and the number of pets. The sponge removes food scraps and hair.

Troubleshooting
If you encounter issues with your Casfuy PWS-155 water fountain, refer to the following common solutions:
- Fountain Not Dispensing Water:
- Check if the power adapter is securely plugged into both the fountain and the wall outlet.
- Ensure the water level in the tank is sufficient (above 30%). Low water levels can cause the pump to stop working.
- Disassemble the pump and clean it thoroughly. Hair or debris can clog the pump impeller.
- Inspect the pump for any visible damage. If the pump is damaged or fails after cleaning, it may need replacement.
- Reduced Water Flow:
- Clean the pump and filter sponge. Accumulation of debris can restrict water flow.
- Replace the filter if it has not been changed recently (recommended every 1-2 weeks). A clogged filter can impede water circulation.
- Unusual Noise from Pump:
- Check the water level. A pump running with insufficient water can make noise.
- Clean the pump. Debris caught in the impeller can cause rattling or grinding sounds.
- Ensure the pump is properly seated in its designated slot and not vibrating against the tank.
- Water Tastes or Smells Bad:
- Replace the multi-layer filter. The activated carbon layer is responsible for removing odors and chlorine.
- Thoroughly clean the entire fountain, including the tank and all components, to remove any biofilm or residue.
