Setup Instructions
- Unpack: Carefully remove the humidifier from its packaging. Retain packaging for storage or future shipping.
- Placement: Place the humidifier on a firm, flat, water-resistant surface at least 6 inches (15 cm) away from walls and appliances. Do not place on carpet or near heat sources.
- Fill Water Tank:
- Ensure the unit is unplugged.
- Remove the top cover.
- Pour clean, cool tap water directly into the water tank opening. Do not fill past the MAX fill line. Distilled water is recommended to minimize mineral dust.
- Replace the top cover securely.
- Connect Power: Plug the power cord into a standard electrical outlet.
Operating Instructions
- Power On/Mist Control: Turn the control knob clockwise to the desired mist output level. The "Power/Refill" indicator light will illuminate green.
- Adjust Mist Direction: Rotate the mist nozzle on top of the unit to direct the mist flow as desired (360° adjustable).
- Aromatherapy (Optional):
- Locate the essential oil pod (usually a small tray or compartment) on the unit.
- Add a few drops of your favorite essential oil onto the aromatherapy pad (if applicable) or directly into the designated pod. Do not add essential oils directly into the water tank.
- The aroma will be diffused with the cool mist.
- Low Water Shut-Off: The humidifier will automatically shut off when the water level is too low. The "Power/Refill" indicator light will turn red. Refill the water tank to resume operation.
- Power Off: Turn the control knob counter-clockwise until it clicks to the "OFF" position. Unplug the unit when not in use.

- Do not use harsh chemicals or abrasive cleaners.
