DIRECTIONS
The openings must not
be obstructed by carpeting when the washing
machine is installed on a
carpeted floor.
INSTALLA TION OF THE UNDER BASE COVER [OPTION]
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
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
at the bottom of the back
2
Check the Horizon
Status
Check the position of tub above
the center of the washer.
1
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.

CONNECTION
FOR ORDINARY TAP
6
Connect the inlet hose adapter
of the hose to the water inlet of
the washer by turning it clockwise to be fixed tightly.
• Please check the rubber packing
inside the inlet hose adapter of
the hose.
1
Pull down the collar
of the inlet hose to
separate it from the
water tap adapter.
2
Loosen the four
screws at the water
tap adapter, but don’t
loosen the screws until
they are separated from
the water tap adapter.
4
Remove the tape,
and screw connector
B into connect A tightly.
5
Connect the inlet
hose to the water tap
adapter by puling down
the collar of the hose end.
3
Connect the water tap
adapter to the water tap tighten the four screws evenly
while pushing up the adapter
so that the rubber packing
can stick to the water tap
tightly .
HOW TO CONNECT THE INLET HOSE
Be careful not to mistake in supplying between the hot(maximum : 50˚C) and cold water.
In using only one water tap or in case of attached one water inlet valve, connect the inlet hose to the cold water inlet
valve.
Do not over tighten : this could cause damage to couplings.
FOR SCREW-SHAPED TAP

FEATURE OF THE WASHING 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.
W ATER 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 SUIT 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 W ASH
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 W ASH
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.

FEATURE
FUNCTIONAL PRINCIPLE
1 The micom can remember the time 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.

Filter
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.
CIRCULA TING-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.

FEATURE
11
FEATURE
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 INDICAT OR 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.
