DIRECTIONS
The openings must not
be obstructed by carpeting when the washing
machine is installed on a
carpeted floor.

How To Install On An Inclined Place
¡ The place where it would be
exposed to direct sunlight.
¡ The place nearby a heater or heat
appliance.
¡ The place where it would be sup-
posed 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
Never install in these places
1 Before installing your
washer, remove the
pad from the bottom
of the cabinet. Then,
separate under cover
from rear side of cabinet by unscrewing
and insert it into the
base.
2 Push the under-base
cover into the end, which
decrease the noise made
by this washer.
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.
SCREW
1 There is under-base
cover in the tub of the
washer. Put out and
draw it in its proper
site. (See picture)
2 Push the under-base
cover into the end, which
decrease the noise made
by this washer.

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 For Blanket Wash
The water level would be lowered because the blanket 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 + 30
Residual drain time.
The time remembered by micom.
Asymmetrically designed pulsator
makes the cyclone water flow, which get
rid of the washing dead zone to
increase the washing effect and reduce
the entanglement of laundry.
Draining
Good draining The washer begins spin process after drainage.

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

Pulsator System
When the pulsator is rotated C.W or C.C.W at a high speed, it makes the cyclone water flow from the asymmetrically
designed pulsator as shown below.
Automatic Drainning time Adjustment
This system adjusts the draining time automatically according to the draining condition.

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.

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.
