3.3 First Use
Before first use, iron an old piece of fabric to remove any manufacturing residues from the soleplate. This may produce a slight odor or smoke, which is normal and will dissipate quickly.
4. Operating Instructions
4.1 Temperature Settings
Plug the iron into a suitable power outlet. The iron features various temperature settings, often indicated by fabric types or a temperature dial. Select the appropriate temperature for your garment. The indicator light will illuminate while the iron is heating up and turn off when the desired temperature is reached.
4.2 Steam Ironing
Steam ironing is effective for most fabrics. Ensure the water tank is filled. Once the iron reaches the set temperature (usually indicated by the light turning off), you can activate the steam function. Use the steam boost button for stubborn creases.

4.3 Dry Ironing
For delicate fabrics or when steam is not desired, ensure the steam function is turned off or the water tank is empty. Select the appropriate temperature and iron without steam.
4.4 Vertical Steaming
The iron can be used for vertical steaming of hanging garments or curtains. Hold the iron vertically a few centimeters away from the fabric and press the steam boost button. Do not allow the hot soleplate to touch the fabric.
5. Maintenance
5.1 Cleaning the Soleplate
To clean the soleplate, ensure the iron is unplugged and completely cool. Wipe the soleplate with a damp cloth and a non-abrasive cleaner if necessary. Do not use abrasive pads or harsh chemicals.
5.2 Descaling
Regular descaling is important to maintain steam performance. Refer to the specific descaling instructions in your full product manual, as procedures may vary. Generally, this involves using a descaling solution or a self-clean function with distilled water.
5.3 Storage
After use, unplug the iron and allow it to cool completely. Empty any remaining water from the tank. Store the iron upright on its heel rest in a safe, dry place, with the cord neatly wrapped.
