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 pulling down
the collar of the hose end.
3
Connect the water tap
adapter to the water tap and
tighten the four screws evenly
while pushing up the adapter
so that the rubber packing
can stick to the water tap
tightly.
§§
è
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 T AP

remained water in the
hose. And put a container
under the filter to collect
water.
2
Turn the cap counterclockwise.
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.

Feature of the Washing Machine
1 The first air bubble washing system in the world.
2 Quiet washing through the innovational low-noise design.
3 The wash effectiveness is much more enhanced because of the air bubble washing system.
4 The laundry detergent dissolves well in water because of the air bubble washing system.
5 The adoption of the water currents to adjust the unbalanced load.
6 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
The water level would be lowered because the clothes absorbs water at the beginning of washing. Therefore, after
60 seconds, the operation is interrupted to check the water level, and then the water is supplied again until the selected water level is reached.

EXPLANATION
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 + 40

11
EXPLANATION
This is the device to dispense the softener automatically by centrifugal force.
This is installed inside the auto-balancer.
FUNCTIONAL PRINCIPLE
1 Softener stays in room (A) when poured into softener inlet.
2 Softener moves from (A) to (B) by centrifugal force during intermittent spin process.
3 Softener flows from (B) to (C) during rinse process next to intermittent spin.
4 Softener moves from (C) to (D) by centrigfugal force during second intermittent spin.
After spin process is finished, the softener is added into the tub through softener outlet.
FLOW OF THE SOFTENER
FLOW OF THE SOFTENER INSIDE OF THE BALANCER
HOW TO CHECK MOVEMENT
Pour a reasonable amount of “MILK” into softener dispenser and operate the washer with no load. In final
rinse cycle, make sure that the milk is added into the
tub through softener outlet.

Water
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 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 vanes 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.
13
EXPLANATION
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.

FUNCTIONAL PRINCIPLE OF TRANS & MAGNET
¡ The phase of A.C electric power changes to 60 cycle/second.
¡ The magnetic pole of trans core is changed by the change of the phase of A.C electric power.
¡ The core repeats push and pull (3600 times/min.) of the armature magnet.
