Tefal GV7810G0 Pro express

This function allows you to iron fabrics in situ or on a hanger.
To do this, set the iron temperature button to the maximum position.
• Leave the item on a hanger and gently pull the fabric with one hand.
• Press the steam control button intermittently and move the iron from top to bottom.
As the steam produced is very hot, it softens the fibres and removes creases.
Note: Never use the vertical steam function on an item being worn by anyone.

To avoid damaging the soleplate, follow this advice:
• Always place your iron on its heel rest or its base (depending on model).
• Avoid ironing over abrasive items (buttons, zip fastenings, etc.).
• Never clean your iron's soleplate with abrasive or metallic pads.

Yes this is because the steam is generated in a separate area away from the soleplate of the iron. This allows you to obtain steam on the lowest heat setting, e.g. silks. However, when the iron temperature control is set to the lowest setting you must also set the steam output control dial (depending on the model) to the low position, otherwise water droplets may appear in the steam.
