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
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.

The openings must not
be obstructed by carpet-
ing when the washing
machine is installed on a
carpeted floor.

FOR ORDINARY TAP
6Connect the inlet hose adapter
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.
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 connector A
tightly.
5Connect the inlet
hose to the water tap
adapter by pulling down
the collar of the hose end.
3Connect the water tap
adapter to the water tap and
tighten the four screws evenly
with 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.

hose to the water tap
by screwing the con-
nector D tightly.

CLEANING THE LINT FILTER
• This washer has two Lint Filters in the top TUB in order to filter off lint and fuzz.
CLEANING THE WATER INLET FILTER
• Clean the filter when water leaks from the water inlet.
3Return the filter as it was, and
insert the filter frame into the
slot.
1Pull the Filter frame
upward. 2Turn the lint filter inside out, wash to
the lint off with water.
1Pull the power plug out
before cleaning it.
2Turn off the water sup-
ply to the washer and
separate the inlet hose.
3Pull the inlet filter out. 4Remove the dirt from
the inlet filter with a
brush.
CLEANING THE DRAIN FILTER
• In case “Pump-Model” 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.
4Clean the drain filter removing
the foreign stuffs.
5Put the filter into the case. And
turn the cap to adjust the promi-
nence of the filter to the hole of
the case.
6Turn the cap clockwise tightly.

Feature of the Washing Machine
1 First applying the Radical Technology in the world ... go beyond washing, sterilize your clothes and deodorize a bad
smell(Option).
2 The first air bubble washing system in the world.
3 Quiet washing through the innovational low-noise design.
4 Improving washing performance by more than 35%, while reducing power consumption by 40%.
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 unbalanced load.)
EFFECT
It reduces vibration and noise effectively while spinning.
WATER FLOW
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 AND TECHNICAL EXPLANATION

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.
condition Bad draining Draining time is prolonged.
No draining Program is stopped and gives the alarm.

channel
Pulsator
This system is to prevent abnormal vibration during intermittent spin and spin process.
FUNCTIONAL PRINCIPLE
1. When the lid is closed, the contact lever A of
the safety switch 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 pro-
cess is interrupted.
3. In case that P.C.B. ASS’Y gets “OFF” signal
from the safety switch, spin process is
stopped and rinse process is started auto-
matically.
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 pul-
sator 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 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
stick 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.

CHECKING METHOD
IN THIS CASE, YOU MUST EMPTY THE SPIN TUB FIRST.
1) TO CHECK THE REVOLUTION OF SPIN TUB.
IF THE SPIN TUB DOES NOT REVOLVE AND ONLY THE PULSATOR IS TURNING, THAT IS
CLUTCH SPRING DEFECT.
2) TO CHECK THE SPIN SPEED(RPM) BETWEEN SPIN TUB AND PULSATOR.
IF YOU FIND THE DIFFERENT SPIN SPEED BETWEEN SPIN TUB AND PULSATOR, THIS IS ALSO
CLUTCH SPRING DEFECT.
