Filling the Water Reservoir for Steam Function:
- Ensure the Steamstyler is unplugged and cool.
- Locate the water reservoir cap on the side of the appliance. Open the cap.

Initial Steam Activation (First Use):
- Remove any protective stickers from the steam control dial located on the back of the handle.
- Plug in the Steamstyler and turn it on. Set your desired temperature (steam activates above 300°F).
