A lifter, operated by a rotating drum, rolls laundry in the drum, and hot air heated by electricity (or gas) dries the
laundry through time or sensor dry system (a temperature control system) under various conditions.
❑What is a Dryer?
1. What is a Dryer?
◆Large Capacity/Time-Saving
• A large quantity of laundry can be dried at a time, saving energy as well as time.
◆Automatic Digital Dry
• The digital sensor measures the humidity of laundry for optimum drying.
◆Large Door and Automatic Dry
• The dryer has a large transparent door for convenient laundry dropping and checking.
◆Dust Filter
• Fluff and dust are filtered during the drying process.
◆Sterilizing Dry
• The high-temperature air dries laundry with sterilizing effects.
◆Drying Shoes
• The dryer rack provided with the unit helps drying shoes as well as sensitive fabric.
◆Child Lock
• This is the function that protects children from harm during the drying process.
2. Key Features

◆Dry Time
• Adjust the length of time for drying.
◆Sensor Dry
• Automatically dry according to the types of laundry.
◆Rack Dry
• Dry sensitive shoes and fabric(e.g. sweaters, silk, lingerie) on the rack.
◆Anti-crease
• Prevent wrinkles in case laundry stays in the drum after the drying process.
◆Damp Signal
• Signals when laundry is damp enough to be ironed.
◆Delay Start
• Preset time indicates staring time of the cycle.
