3. DIRECTIONS FOR INSTALLATION AND USE
INSTALLING PLACE
Install the washer on a horizontal
solid floor. If the washer is installed
on an unsuitable floor, it could make
considerable noise and vibration.
Never install in these places
¡ The place where it would be exposed to
direct sunlight.
10Cm
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.
¡ 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.
§ INSTALLATION OF THE UNDER BASE COVER [OPTION]
1
The packing box
opened, there is a
noise insulation plate
at the bottom of the back
2
Push the noise insulation plate
into the end, which decrease
the noise made by this washer.
§ HOW TO INSTALL ON AN INCLINED PLACE
1
Horizon
Setting
After controlling the height
by turning the adjustable
leg, let the washer put
down to the ground.
2
Check the Horizon
Status
Check the position of tub above
the center of the washer.
NOTES
The openings must not
be obstructed by carpeting when the washing
machine is installed on a
carpeted floor.

DIRECTIONS
§ 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 ORDINARY TAP
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.
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.
TAPE
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
6
Connect the inlet hose adapter
of the hose to the water inlet of
the washer by turning it clockwise to be fixed tightly.
Connector A
Connector B
• Please check the rubber packing
inside the inlet hose adapter of
the hose.
FOR SCREW-SHAPED TAP
1
Connect the inlet
hose to the water tap
by screwing the connector D tightly.
2
Connect the connector-inlet supplied if
necessary.
3
Insert the inlet hose adapter
into the water inlet of a washer
and turn it to be fixed.

4. FEATURE AND TECHNICAL EXPLANATION
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.
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 SUIT course have no operation of the water currents to adjust the unbalnced load.)
EFFECT
It reduces vibration and noise effectively while spinning.

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 selected water level is reached.

FUNCTIONAL PRINCIPLE OF BUBBLE WASHING MACHINE
ACROSS SECTION
Air bubble
Tub
Outer tub
Pulsator
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.
AUTOMATIC DRAINNING TIME ADJUSTMENT
This system adjusts the draining time automatically according to the draining condition.
Good draining
The washer begins spin process after drainage.
Bad draining
Draininig time is prolonged.
No draining
Program is stopped and gives the alarm.

FEATURE
AUTOMATIC UNBALANCE ADJUSTMENT
This system is to prevent abnormal vibration during intermittent spin and spin process.
FUNCTIONAL PRINCIPLE
Contact of safety switch Lid closing
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.

NOTES

it. Check the unbalance of the wash load and the installation condition.
CIRCULATING-WATER COURSE AND LINT FILTER
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.

LINT FILTER
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.

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.

HOW TO CHECK THE CLUTCH SPRING PROBLEM
PROBLEM
1) THE LAUNDARY IS IN THE SPIN TUB UNEVENLY WHEN JUST STARTING SPIN PROCESS.
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 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 PUSATOR, THIS IS ALSO
CLUTCH SPRING DEFECT.
IN THIS CASE, WE ARE GOING TO SUPPLY THE CLUTCH BOSS ASSEMBLY INSTEAD OF GEAR

CONCERNING ERROR MESSAGE
MESSAGE
CAUSE
SOLUTION
Improper installation of drain hose.
Install drain hose properly.
The drain hose is blocked up by foreign
matter.
Remove foreign matter from drain hose.
Drain motor is inferior.
Change drain motor.
The water tap is closed.
Open the water tap.
The water inlet filter clogged.
Clean the water inlet filter.
It passes over the 60 minutes, yet it doesn’t
come to assigned water level.
Check whether or not is comes to the
assigned water level.
Wash loads get uneven during spin.
Re-set wash loads evenly.
Poor installation of the unit.
Proper installation.
The lid is opened.
Close the lid.
