How To Install On An Inclined Place
● The place where it would be exposed to
direct sunlight.
● The place nearby a heater or heat
appliance.
● The place where it would be supposed
to be frozen in winter.
● The kitchen with coal gas and a damp
place like a bathroom.
NOTES
Install the washer on a horizontal
solid floor. If the washer is installed
on an unsuitable floor, it could make
considerable noise and vibration.
INSTALLING PLACE
Never install in these places
2
Push the noise insulation plate
into the end, which decrease
the noise made by this
washer.
1
The packing box
opened, there is a
noise insulation plate.
Put the noise insulation
plate at the bottom of
the back.
2
Check the Horizon
Status
Check the position of tub above
the center of the washer.

Horizon
Setting
After controlling the height
by turning the adjustable
leg, let the washer put
down to the ground.
Keep the machine body
more than 25cm apart from
the wall surface. It will
make easy cleaning the
drain filter which is equipped
at the back side of it. And if
it comes into contract
vibration may occur.

insert the filter frame into the
slot.
1
Pull the Filter frame
upward.
2
Turn the lint filter
inside out, wash to
the lint off with water.
1
Put down the
remained water in the
hose. And put a container
under the filter to collect
water.
2
Turn the cap counter
clockwise.
3
Pull out the filter assembly off
the case of the main body.
6
Turn the cap clockwise tightly.
4
Clean the drain filter
removing the foreign
stuffs.
5
Put in the filter along the

FEATURE OF THE W ASHING MACHINE
1 The first applying Radical Technology in the world....go beyond washing, sterilize your clothes and deodorize a
bad smell.(optional function)
2 The first air bubble washing system in the world.
3 Quiet washing through the innovational low-noise design.
4 The wash effectiveness is much more enhanced because of the air bubble washing system.
5 The laundry detergent dissolves well in water because of the air bubble washing system.
6 The adoption of the water currents to adjust the unbalanced load.
7 One-touch operation system.
WATER CURRENT TO ADJUST THE UNBALANCED LOAD
It is a function to prevent eccentricity of the clothes after wash by rotating pulsator C.W and C.C.W for 35
seconds.(But, the DELICATE course have no operation of the water currents to adjust the unbalnced load.)
EFFECT
It reduces vibration and noise effectively while spinning.
WATER FLOW
FUNCTION FOR SOAK WASH(OPTION)
DISPLAY THE RESIDUAL TIME
When the SOAK WASH is selected, the total wash time increases because 60 minutes for soak process are added
to the time of main process.
PROGRESS
AUTOMATIC W ATER SUPPLY SYSTEM FOR BLANKET WASH
The water level would be lowered because the blanket absorbs water at the beginning of washing. Therefore, after
2 minutes, the operation is interrupted to check the water level, and then the water is supplied again until the
selected water level is reached.
‘ ’ mark indicates the operation of the water currents to adjust the unbalanced load.

FUNCTIONAL PRINCIPLE
1 The micom can remember the time(D) from the begining of drain to reset point when the pressure switch reaches
to “OFF” point
2 In case of continuous draining, residual drain time is determined by micom.
Draining time as a whole = D + 90
Residual drain time.
The time remembered by micom.
FUNCTIONAL PRINCIPLE
Bubble Motor supplies the air from the bottom of outer tub to the inner space of pulsator, the air is dispersed by the
rotation of pulsator. Air-bubble is created by the centrifugal force, and rises up.
Draining
Good draining The washer begins spin process after drainage.

Pulsator
This system is to prevent abnormal vibration during intermittent spin and spin process.
FUNCTIONAL PRINCIPLE
1 When the lid is closed, the safety switch
contact is “ON” position.
2 In case that wash loads get uneven during
spin, the outer tub hits the safety switch
due to the serious vibration, and the spin
process is interrupted.
3 In case that P.C.B. ASS’Y gets “OFF”
signal from the safety switch, spin process
are stopped and rinse process is started
automatically by P.C.B. ASS’Y.
4 If the safety switch is operated due to the
unbalance of the tub, the program is
stopped and the alarm is given.
CIRCULATING-WATER
The washing and rinsing effects have been
improved by adopting the water system in
which water in the tub is circulated in a
designed pattern.
When the pulsator rotates during the washing
or rinsing process, the water below the
pulsator fans creates a water currents as
shown in figure.
The water is then discharged from the upper
part of the tub through the water channel.
About 40 L/min. water is circulated at the ‘high’
water level, standard wash load and standard
water currents.
Page 11
FEATURE AND TECHNICAL EXPLANATION
10
Much lint may be obtained according to the kind of clothes
to be washed and some of the lint may also sticks to the
clothes.
To minimize this possibility a lint filter is provided on the
upper part of the tub to filter the wash water as it is
discharged from the water channel. It is good to use the lint
filter during washing.
HOW TO REPLACE LINT FILTER
1 Pull the filter frame upward.
2 Turn the lint filter inside out, and wash the lint off with water.
3 Return the filter as it was, and fix the filter frame to the slot.
When the START/HOLD button is pressed, the residual time (min.) is displayed on the time indicator, and it will be
counted down according to process.
When operation is finished, the TIME INDICATOR will light up .
STRUCTURE
FUNCTIONAL PRINCIPLE
1 When the DRAIN MOTOR connected to the power source, the DRAIN MOTOR rotates with 900 r.p.m and
revolves the pulley by gear assembly for reducing.
2 When the pulley is rotated, the pulley winds the wire to open the drain valve.
3 Therefore, rotation of pulley changed to the linear moving of wire.
4 The wire pulls the brake lever of Gear Mechanism Ass’y within 5 seconds.
5 After the wire pulled, gear assembly is separated from motor and condition of pulling is held by operation of the
lever.
6 When the power is turned off, the drain valve is closed because the wire returns to original position.

MESSAGE CAUSE SOLUTION
Improper installation of drain hose.
The drain hose is blocked up by foreign
matter.
Drain motor or drain pump is inferior.
The water tap is closed.
The water inlet filter clogged.
It passes over the 60 minutes, yet it doesn’t
come to assigned water level.
Wash loads get uneven during spin.
Poor installation of the unit.
The lid is opened.
The safety switch is inferior.
The load sensing is inferior. After the load
sensing operates about 7 seconds, the
message is displayed during 0.5 second
and water level is always fixed ‘high’.
The water level sensing is inferior.
Install drain hose properly.
Remove foreign matter from drain hose.
Change drain motor or drain pump.
Open the water tap.
Clean the water inlet filter.
Check whether or not is comes to the
assigned water level.
Re-set wash loads evenly.
Proper installation.
Close the lid.
Change the safety switch.
Change the P.C.B. ASS’Y.
Check the water level sensor and the
contact part of the connector.
