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-

¡ 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.

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.

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 SUPPL Y 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.

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.

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.

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.

2) THEREFORE, IT CAUSE THE SERIOUS NOISE AND VIBRATION WHEN WASHING AND SPINNING
PROCESS OR SUPPLING WATER IRREGULARY WHEN SPINNING PROCESS
AND CAUSE SHORT OF SPIN PERFORMANCE.
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 REVOL VE AND ONLY
THE PULSA T OR IS TURNING, THAT IS CLUTCH SPRING DEFECT.
2) TO CHECK THE SPIN SPEED(RPM) BETWEEN SPIN TUB AND PULSA T OR.
IF YOU FIND THE DIFFERENT SPIN SPEED BETWEEN SPIN TUB AND PUSATOR, THIS IS ALSO
CLUTCH SPRING DEFECT.

- Use fixing jig and 17mm
socket wrench as if disassembling, as fastening torque
about 100~200kgf-cm.
- Check the end-play, up and
downward and check the
binding force, too much or
not on bi-direct of rotation.
Finally , check the distance
between brake lever and control bolt. (2~3mm)
Also, check the interferance
depth both clutch tip and clutch
boss(3.5~4.5mm)

MESSAGE CAUSE SOLUTION
Improper installation of drain hose.
The drain hose is blocked up by foreign
matter.
Drain motor 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.
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.
