Setup
1. Unpacking
Carefully remove the humidifier from its packaging. Retain all packaging materials for future storage or transport. Ensure all components are present: main unit, water tank, power cord, and remote control.
2. Placement
Place the humidifier on a flat, stable, and water-resistant surface at least 6 inches (15 cm) away from walls and furniture. Ensure the mist outlet is not obstructed. For optimal performance in large rooms, position it centrally or in an area where mist can disperse freely.
3. Filling the Water Tank
The AILINKE humidifier features a convenient top-fill design. Open the top cover and pour clean, cool tap water directly into the water tank. Do not exceed the maximum fill line. For best results and to prevent mineral buildup, use distilled or demineralized water.
