Setup Instructions
1. Unpacking and Placement
- Carefully remove all packaging materials and ensure all components are present.
- Place the humidifier on a flat, stable, and water-resistant surface. Ensure it is at least 12 inches (30 cm) away from walls, furniture, and electronic devices.
- The built-in casters allow for easy movement. Simply push the unit to your desired location.
2. Assembling the Extension Tube (Optional)
- If you wish to elevate the mist output, gently insert the extension tube into the mist outlet on the top cover. Ensure it is securely seated.
3. Filling the Water Tank
The humidifier offers two convenient ways to fill the water tank:
- Top Water Filling: Remove the top cover and pour water directly into the opening until it reaches the 'MAX' line indicated on the water level window.
- Water Tank Filling: Lift the main unit off the base to access the water tank. Carry the tank to a sink and fill it with water. Replace the main unit securely onto the base.
Note: Always use clean, cool tap water. Distilled or demineralized water is highly recommended to minimize mineral dust and extend the life of the humidifier.
