Operating Instructions
Filling the Water Tank:
The Syvio humidifier features a convenient top-fill design.
- Remove the top cover of the humidifier.
- Pour clean, cool tap water directly into the tank. Do not exceed the "Max" water level line to avoid damage. For best results and to extend the humidifier's life, fill to the "Best" line.
- Do not pour water into the central pipe or directly into the base to prevent leakage.
- Replace the top cover securely.

Powering On and Mist Control:

Warm & Cool Mist Function:
The humidifier offers both warm and cool mist options for year-round comfort.
- Press the Warm Mist button (⑤) to activate warm mist. Warm mist helps to quickly humidify the air and can be soothing in colder months.
- The humidifier defaults to cool mist when first turned on or when the warm mist function is deactivated. Cool mist is ideal for maintaining moisture in warmer seasons and for general use.

Smart Auto Constant Humidity Mode:
This feature allows the humidifier to automatically maintain a desired humidity level.
- Press the Auto Mode button (②) repeatedly to set your target humidity (e.g., 50%RH, 60%RH).
- The humidifier will automatically turn on when the ambient humidity drops below your set target and turn off when it reaches the target.
- To disable auto mode and allow continuous humidification, select the "--" setting.

Maintenance
Regular cleaning is essential to prevent mineral buildup and ensure optimal performance and hygiene of your humidifier. Always unplug the unit before cleaning.
Cleaning Procedure:
Video 1: This video demonstrates the easy cleaning process for the Syvio 6L Humidifier.
- Open and Empty: Open the lid and pour out any remaining water from the tank. Also, pour out water from the bottom groove of the base.
- Protect Components: Before cleaning the base, place the waterproof cover over the delicate components to protect them from water.
- Clean Base: Use the provided brush to clean the bottom groove and any hard-to-reach areas in the base.
- Wipe Down: Use a soft towel to wipe down the inside of the water tank and the bottom groove of the base.
- Remove Cover: Be sure to remove the waterproof cover from the base before using the humidifier again.
Descaling (Mineral Deposit Removal):
If you notice a white powder or film on surfaces, it indicates mineral buildup from hard water. Regular descaling is recommended.
- Mix a solution of equal parts white vinegar and water.
- Pour the solution into the base and water tank, ensuring it covers any mineral deposits. Let it soak for 30 minutes to an hour, or longer for heavy buildup.
- Use a soft brush or cloth to gently scrub away the deposits.
- Rinse thoroughly with clean water until the vinegar smell is gone.
