machine is installed on a
carpeted floor.

Installation Of The Noise Inulation Plate

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

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.

Insert the inlet hose adapter
into the water inlet of a washer
and turn it to be fixed.

• Check the packing in the inlet

then close the Cocer.

3

Assemble the Lint Filter as it
was, by pushing toward wall

with fixing slot

1Pull the power

plug out before
cleaning it.

2Turn off the water

supply to the
washer and
sperate the inlet
hose.

3Pull the inlet filter

CONVENIENCE

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.

1

Put down the
remained water in the
hose. And put a container
under the filter to collect
water.

2

Turn the cap counter
clockwise.

3

Pull out the filter assembly off
the case of the main body.

6

Turn the cap clockwise tightly.

4

Clean 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 of the Washing Machine

1 First applying the Radical Technology in the world ... go beyond washing, sterilize your colthes and deodorize a bad

smell.
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 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

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.

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

channel

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 con-

tact 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.

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 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.
