Important Safety Instructions
When using your steam generator iron, basic safety precautions should always be followed, including the following:
- Read all instructions before using the iron.
- Use the iron only for its intended use.
- To protect against a risk of electric shock, do not immerse the iron in water or other liquids.
- The iron must always be turned to "Off" before plugging or unplugging from the outlet. Never yank cord to disconnect from outlet; instead, grasp plug and pull to disconnect.
- Do not allow cord to touch hot surfaces. Let iron cool completely before putting away. Loop cord loosely around iron when storing.
- Always disconnect iron from electrical outlet when filling with water or emptying, and when not in use.
- Do not operate iron with a damaged cord or if the iron has been dropped or damaged. To avoid the risk of electric shock, do not disassemble the iron; take it to a qualified serviceman for examination and repair. Incorrect reassembly can cause a risk of electric shock when the iron is used.
- Close supervision is necessary for any appliance being used by or near children. Do not leave iron unattended while connected or on an ironing board.
- Burns can occur from touching hot metal parts, hot water, or steam. Use caution when you turn a steam iron upside down – there may be hot water in the reservoir.
- The iron must be used and rested on a stable surface.
- When placing the iron on its stand, ensure that the surface on which the stand is placed is stable.
- This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

Operating Instructions
Your Tefal Pro Express Ultimate GV9550 offers powerful steam performance for efficient ironing.
- Power On: Press the On/Off button on the base unit. The indicator light will illuminate, and the iron will begin to heat up. This usually takes a few minutes.
- Select Settings:
- The iron features intelligent technology that automatically adjusts temperature and steam output for all ironable fabrics.
- For specific needs, you can select different steam modes (e.g., Eco, Normal, Max) using the control panel on the base unit.
- The iron delivers a continuous steam output of up to 120 g/min, with an impressive 8 bar pressure, ensuring deep penetration into fabric fibers.
- Ironing:
- Once the iron is ready (indicator light stops flashing or turns solid), press the steam trigger located under the handle to release steam.
- Move the iron smoothly over your garments. The high-pressure steam and Durilium Airglide Autoclean soleplate ensure excellent glide and efficient wrinkle removal.
