Water consumption is reduced by using the power of the laundry falling (free-fall) created when rotating
the drum resembling a sieve net. With temperature control system, this drum washing machine saves
energy and improves washing performance at the same time.

"Simultaneous supply of cold#hot water
As cold and hot water is supplied at the same time, heating time and energy is saved.
"Top-quality popup dial
The top-quality popup dial is used only during washing process.
"Dust filter
Filter to remove foreign substances, such as naps generated during washing, etc., is installed inside the
drum.
"DD inverter motor
The direct-drive type, of which motor is directly connected to drum without an interim clutch,
significantly reduces noise and vibration.
"Heating device is installed to enable boiling of the laundry.
"Large door creates grand appearance and makes it easy to put in and out the laundry.
"For pump drainage, the powerful pump speeds up drainage process.

$Washing
When rotating drum after putting in the laundry and detergent into the drum, the laundry are rotated by
protrusions (lifters) attached inside the drum.
Washing is carried out with bending and impact actions generated by falling of the laundry to the top
part of drum.
%Rinsing
Rinsing cleanly washes out detergent and dirt removed from the laundry after washing cycle.
&Spin-drying
Weak, standard and strong cycles can be selected according to types of fabrics to be washed. Spin-
drying is carried out by rotation (the centrifugal force) of drum according to the designated speed.
