DIRECTIONS
The openings must not
be obstructed by carpet-
ing when the washing
machine is installed on a
carpeted floor.
■■Installation Of the COVER UNDER (Noise Insulation 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
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.
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
2Push the COVER UNDER to
the end. This reduces the
noise from washing machine.
1In the packing box or
the tub of the washer,
there is the COVER
UNDER. Put the
COVER UNDER at the
bottom of the back.
2Check the Horizon
Status
Check the position of tub above
the center of the washer.
1Horizon
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
6Connect the inlet hose adapter
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.
1Pull down the collar
of the inlet hose to
separate it from the
water tap adapter. 2Loosen the four
screws at the water
tap adapter, but don’t
loosen the screws until
they are separated from
the water tap adapter.
4Remove the tape,
and screw connector
B into connector A
tightly. 5Connect the inlet
hose to the water tap
adapter by pulling down
the collar of the hose end.
3Connect the water tap
adapter to the water tap and
tighten the four screws evenly
with 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.
FOR SCREW-SHAPED TAP 3Insert the inlet hose adapter
into the water inlet of a washer
and turn it to be fixed.
• Check the packing in the inlet
1Connect the inlet
hose to the water tap
by screwing the
connector D tightly. 2Connect the
connector-inlet
supplied if necessary.

HOW TO CLEAN THE FILTER
4
Remove the dirt
from the inlet filter
with a brush.
1
Pull the
power plug
out before
cleaning it.
2
Turn off the
water supply
to the washer
and sperate the
inlet hose.
3
Pull the
inlet filter out.
CLEANING THE LINT FILTER
CLEANING THE WATER INLET FILTER
• Clean the filter when water leaks from, the water inlet.
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.
3Return the filter as it was, and
insert the filter frame into the
slot.
1Pull the Filter frame
upward. 2Turn the lint filter inside out, wash to
the lint off with water.
1Put down the
remained water in the
hose. And put a container
under the filter to collect
water.
2Turn the cap counter
clockwise. 3Pull out the filter assembly off the case of the main body.
6Turn the cap clockwise tightly.
4Clean the drain filter
removing the foreign
stuffs. 5

Feature of the Washing Machine
1 First applying the Radical Technology in the world ... go beyond washing, sterilize your clothes 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 60
seconds.(But, the SUIT course have no operation of the water currents to adjust the unbalanced 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 Good draining The washer begins spin process after drainage.
condition Bad draining Draininig time is prolonged.
No draining Program is stopped and gives the alarm.

channel
Pulsator
This system is to prevent abnormal vibration during intermittent spin and spin process.
FUNCTIONAL PRINCIPLE
1. When the lid is closed, the micro 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 is
stopped and rinse process is started
automatically.
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.
