3. Setup
The Waterdrop WD-A1 is designed for easy, installation-free setup. No drilling or plumbing is required.
Initial Setup Steps:
- Unpacking: Carefully remove the dispenser and all components from the packaging.
- Placement: Place the dispenser on a stable, flat surface in your kitchen, office, bedroom, or living room. Ensure there is at least 20cm of space on the sides for proper ventilation.
- Power Connection: Plug the power cable into a suitable electrical outlet.
- Water Tank Filling: Fill the raw water tank with tap water.
- Initial Rinse: Upon initial power-on, the system will automatically initiate a comprehensive 30-minute rinsing process. During this process, the water in the wastewater tank will need to be emptied and the raw water tank refilled approximately three times. This ensures the system is clean and ready for use.

4. Operating Instructions
The Waterdrop WD-A1 features an intelligent OLED display and touch controls for easy operation.
Using the Smart OLED Screen:
The OLED screen provides real-time information on water quality (TDS), current water temperature, selected water volume, and filter lifespan. Use the smart touch keys to navigate and select options.

Temperature and Volume Selection:
The dispenser offers 6 preset temperature options and 5 standard cup volumes. Select your desired temperature and volume using the touch interface.
- Temperature Options: 5°C (Iced Lemon Water), Ambient, 45°C (Baby Formula), 65°C (Tea), 85°C (Coffee), 95°C (Oatmeal).
- Volume Options: 150ml, 250ml, 350ml, 500ml, Max.

Note on Hot Water: The WD-A1 heats water in real-time without an integrated hot water tank. External factors like weather conditions and initial cup temperature may slightly influence the dispensed water temperature.
Safety Features:
- Child Lock: Prevents accidental dispensing of hot water, reducing the risk of burns.
- Ambient Lighting: Three-color ambient lighting indicates the water temperature (e.g., blue for cold, red for hot), providing a visual cue even at night.

Multiple Operating Modes:
The dispenser includes several modes to optimize performance and energy consumption:
- Night Mode: Activates silent operation and energy-saving features, ideal for homes or offices during off-hours.
- Away Mode: Allows for draining stagnant water, ensuring fresh water upon return.
- Altitude Mode: Corrects the boiling point for accurate temperature dispensing in high-altitude environments.

5. Maintenance
Regular maintenance ensures optimal performance and longevity of your Waterdrop WD-A1 dispenser.
Filter Replacement:
The OLED screen will indicate when filters need replacement. Follow the instructions on the display or in the detailed filter replacement guide (if provided separately) to change the 7-stage RO filter. Using genuine Waterdrop replacement filters is recommended.

Cleaning:
- Exterior: Wipe the exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Drip Tray: Regularly remove and clean the drip tray to prevent water buildup and maintain hygiene.
- Water Tanks: Periodically clean the raw water and wastewater tanks. The separation of these tanks ensures efficient purification and prevents repeated filtration, extending the RO membrane's lifespan.

| No water dispensed | Raw water tank empty; power off; child lock active. | Refill raw water tank; check power connection; deactivate child lock. |
| Water tastes unusual | New filter not rinsed; filter lifespan expired. | Perform initial rinse cycle; replace filter as indicated on OLED screen. |
| Slow water flow | Filter clogged or expired. | Check filter status on OLED screen and replace if necessary. |
| Display not working | Power issue; system error. | Ensure power is connected; try restarting the unit by unplugging and replugging. |
