Introduction
The BONECO S200 Steam Humidifier provides hygienic and efficient humidification for your living space. This manual contains important information regarding the setup, operation, maintenance, and troubleshooting of your S200 humidifier to ensure optimal performance and longevity.
The S200 utilizes steam technology, boiling water to eliminate bacteria and minerals before releasing a pleasant, hand-warm mist into the air. It features a simple control knob for two output levels and a dedicated cleaning mode for easy maintenance.
Setup and Initial Operation
Unpacking
Carefully remove all components from the packaging. Ensure all parts are present:
- BONECO S200 Steam Humidifier Unit
- Water Tank
- Anti-Mineral Pads (2 included)
- Quick Setup Guide
Placement
Place the humidifier on a firm, level, and water-resistant surface. Ensure it is not placed directly against a wall or furniture to allow for proper air circulation. Keep it away from heat sources and direct sunlight.
Filling the Water Tank
- Remove the water tank from the base unit.
- Unscrew the tank cap and fill the tank with clean tap water. Distilled water can be used to minimize mineral buildup, though not strictly required due to the boiling process and cleaning mode.

Automatic Shut-off
The S200 is equipped with an automatic shut-off feature. When the water tank is empty, the unit will automatically turn off to prevent damage. A helpful reminder light will illuminate to indicate that the water tank needs refilling.
Using the Fragrance Tray
The S200 includes a fragrance tray for use with essential oils to enhance your room's atmosphere.
- Locate the small fragrance tray on the top of the unit, near the steam outlet.
- Add a few drops of your preferred essential oil directly into the tray. Do not add essential oils directly into the water tank.
- The aroma will be diffused with the steam into the room.
