How To Install On An Inclined Place
●The place where it would be exposed to
direct sunlight.
●The place nearby a heater or heat appli-
ance.
●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
10Cm
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
2Push the noise insulation plate
into the end, which decrease
the noise made by this washer.
1The packing box
opened, there is a
noise insulation plate
at the bottom of the back
2Check the Horizon
Status
Check the position of tub above
the center of the washer.
1Horizon
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 vibra-
tion may occur.

CONNECTION
FOR ORDINARY TAP
6Connect the inlet hose adapter
of the hose to the water inlet of
the washer by turning it clock-
wise to be fixed tightly.
•Please check the rubber packing
inside the inlet hose adapter of
the hose.
1Pull down the collar
of the inlet hose to
separate it from the
water tap adapter. 2Loosen the four
screws at the water
tap adapter, but don’t
loosen the screws until
they are separated from
the water tap adapter.
4Remove the tape,
and screw connector
B into connect A tightly. 5Connect the inlet
hose to the water tap
adapter by puling down
the collar of the hose end.
3Connect the water tap
adapter to the water tap tight-
en 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 3Insert the inlet hose adapter
into the water inlet of a washer
and turn it to be fixed.
•Check the packing in the inlet
1Connect the inlet
hose to the water tap
by screwing the con-
nector D tightly. 2Connect the connec-
tor-inlet supplied if
necessary.

Remove the dirt
from the inlet filter
with a brush.
1
Pull the
power plug
out before
cleaning it.
2
Turn off the
water supply
to the washer
and sperate the
inlet hose.
3
Pull the
inlet filter out.
CLEANING THE LINT FILTER
CLEANING THE WATER INLET FILTER
•Clean the filter when water leaks from, the water inlet.
CLEANING THE DRAIN FILTER
•In case “U”shape drain hose, this filter’s equipped at the back side of washer.
•This drain filter is to screen the foreign stuffs such as threads, coins, pins, buttons etc ...
•If the drain filter is not cleaned at proper time (every 10 times of use), Drain problem could be caused.
1Put down the
remained water in the
hose. And put a container
under the filter to collect
water.
2Turn the cap counter
clockwise. 3Pull out the filter assembly off the case of the main body.
6Turn the cap clockwise tightly.
4Clean the drain filter
removing the foreign
stuffs. 5
Put in the filter along the
guiding prominence of the
case. Please note the left
position of the filter adjusting
the groove to the guide rib.

FEATURE
Feature of the Washing Machine
1First applying the Radical Technology in the world ... go beyond washing, sterilize your colthes and deodorize a bad
smell.
2The first air bubble washing system in the world.
3Quiet washing through the innovational low-noise design.
4Improving washing performance by more than 35%, while reducing power consumption by 40%.
5The laundry detergent dissolves well in water because of the air bubble washing system.
6The adoption of the water currents to adjust the unbalanced load.
7One-touch operation system.
Automatic Water 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 select-
ed water level is reached.

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 Agitator, the air is dispersed
by the rotation of Pulsator Agitator. Air-bubble is created by the centrifugal force, and rises up.
Draining Good draining The washer begins spin process after drainage.
condition Bad draining Draininig time is prolonged.
No draining Program is stopped and gives the alarm.

channel
Pulsator
Agitator
This system is to prevent abnormal vibration during intermittent spin and spin process.
FUNCTIONAL PRINCIPLE
1When the lid is closed, the safety switch con-
tact is “ON”position.
2In 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.
3In case that P.C.B. ASS’Y gets “OFF”signal
from the safety switch, spin process are
stopped and rinse process is started auto-
matically by P.C.B. ASS’Y.
4If 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 Agitator rotates during the
washing or rinsing process, the water below
the Pulsator Agitator fans creates a water cur-
rents 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.

10
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 in
the center of pulsator agitator 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
1Pull the cap agitator upward.
2Turn the lint filter inside out, and wash the lint off with water.
3Return the filter as it was, and fix the filter lint into the pulsator agitator.
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
1When 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.
2When the pulley is rotated, the pulley winds the wire to open the drain valve.
3Therefore, rotation of pulley changed to the linear moving of wire.
4The wire pulls the brake lever of Gear Mechanism Ass’y within 5 seconds.
5After the wire pulled, gear assembly is separated from motor and condition of pulling is held by operation of the
lever.
6When the power is turned off, the drain valve is closed because the wire returns to original position.
