3. Setup Instructions
Follow these steps to assemble and prepare your water fountain for use:
- Clean Components: Before first use, thoroughly rinse the clean water tank, wastewater tank, and stainless steel drinking tray with mild soap and water. Wipe the main unit with a damp cloth (do not submerge the main unit in water).
- Assemble Tanks: Place the wastewater tank into its designated slot on the main unit. Ensure the red sensor is facing upwards for accurate level detection. Then, place the clean water tank next to it.
- Install Sponge: Insert the black reusable sponge into the slot within the drinking tray. This sponge helps catch hair and food particles.
- Place Drinking Tray: Position the stainless steel drinking tray onto the top of the main unit, ensuring it sits securely.
- Fill Water Tank: Fill the clean water tank with fresh water up to the maximum fill line.
- Power On: Connect the USB charging cable to the main unit and plug the power adapter into a wall outlet to charge the internal battery or operate in continuous flow mode.

4. Operating Modes
The HAPAW P003 offers two operating modes and flexible power options:
- Mode 1: Continuous Flow Mode
When plugged into a power source, the fountain will continuously circulate water. This mode is ideal for encouraging pets to drink more frequently. Note: The machine cannot be turned off when continuously plugged in. - Mode 2: Sensor-Activated Flow Mode
When operating on battery power, the fountain will activate when a pet approaches within 1-1.5 meters, dispensing water for 1 minute. This conserves battery life, allowing it to last over 15 days on a single charge. Continuous flow is disabled in battery mode.
Power Options:
- Plugged-in: For continuous operation and charging.
- Battery Powered: For wireless placement and sensor-activated mode. The built-in 5000mAh rechargeable battery provides extended use.
Automatic Drainage:
- In Mode 1, long-press the mode button to set automatic drainage for 24 hours (slow flashing) or 48 hours (fast flashing).
- In Mode 2, press and hold the mode button for 2 seconds to activate the drain valve for manual draining.

5. Maintenance and Cleaning
Regular cleaning is essential to ensure your pet always has access to fresh water and to prolong the life of the fountain.
- Daily Check: Monitor the water levels in both tanks daily. Refill the clean water tank as needed.
- Weekly Cleaning (Tanks & Tray): Rinse the clean water tank, wastewater tank, and stainless steel drinking tray with mild soap and water. It is recommended to clean the circulatory system fittings and water tank once a week.
- Main Unit: The main unit is not water washable. Wipe it down with a damp cloth to clean.
- Sponge Maintenance: The black sponge is reusable. Rinse it regularly to remove trapped hair and food particles. Replace the sponge every 3 months or as needed.
- Water Level Probes: Pet saliva or oil may cover the water level probes and cause malfunctions (e.g., noise or no water flow). If this happens, wipe the metal probes with a dry paper towel.
