5. DIRECTIONS FOR INSTALLATION AND USE
DIRECTIONS
The opening must not be obstructed by carpeting when the washing machine is installed on a carpeted floor.
§§ è
Location Of Washer
Check location where washer will be installed. Make sure you have everything necessary for correct installation.
Proper installation is your responsibility.
• Do not place or store your washer below 0˚C(32˚F) to avoid any damage from freezing.
• Install the washer on the horizontal sold foor.
NOTES
If the washer is installed on an unsuitable floor, it could make consider-
able noise, vibrate and cause a malfunction.
If washer is not level, adjust the front leg(A) up or down for horizontal set-
ting.
• Earthed electrical outlet(B) is required with 20cm of bottom back of
washer cabinet.
• Hot and cold water faucets (C) must be within 1M of the upper back of
the washer cabinet and provide water pressure 0.3kgf/cm2-
8kgf/cm2(2.94N/cm2-78.4N/cm2).
§§ è
Drain System
Never forget to install drain hose before operating your washer.
The packing box is opened, there are a drain hose.
• Conect the drain hose to the drain outlet at the back side of the washer.
Non-Pump Model Pump Model
1In case that it goes over a door sill.
Don’t let the height of the drain
hose exceed 20cm from the bottom

CONNECTION
FOR ORDINARY TAP
6Connect the inlet hose adapter
of the hose to the water inlet of
the washer by turning it clock-
wise to be fixed tightly.
• Please check the rubber packing
inside the inlet hose adapter of
the hose.
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 connect 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
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 TAP 3Insert the inlet hose adapter
into the water inlet of washer
and turn it to be fixed.
• Assert the packing in the inlet

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 separate
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 of “U” shaped 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 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
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
1The first air bubble washing system in the world.
2Quiet washing through the innovational low-noise design.
3The wash effectiveness is much more enhanced because of the air bubble washing system.
4The laundry detergent dissolves well in water because of the air bubble washing system.
5The adoption of the water currents to adjust the unbalanced load.
6One-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 select-
ed water level is reached.

12
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 Residual drain time.
The time remembered by micom.
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.

Automatic Drainning time Adjustment
This system adjusts the draining time automatically according to the draining condition.

13
EXPLANATION
This is the device to dispense the softener automatically by centrifugal force.
This is installed inside the auto-balancer.
FUNCTIONAL PRINCIPLE
1Softener stays in room (A) when poured into softener inlet.
2Softener moves from (A) to (B) by centrifugal force during intermittent spin process.
3Softener flows from (B) to (C) during rinse process next to intermittent spin.
4Softener 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 dis-
penser and operate the washer with no load. In final
rinse cycle, make sure that the milk is added into the
tub through softener outlet.

installation condition.
NOTES
Filter Tub

Water
channel
Pulsator
This system is to prevent abnormal vibration during intermittent spin and spin process.
FUNCTIONAL PRINCIPLE
1When the lid is closed, the safety switch contact is “ON” position.
2In 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.
3In 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.
4If 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 pul-
sator 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.

15
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
1Pull the filter frame upward.
2Turn the lint filter inside out, and wash the lint off with water.
3Return 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
1When 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.
2When the pulley is rotated, the pulley winds the wire to open the drain valve.
3Therefore, rotation of pulley changed to the linear moving of wire.
4The wire pulls the brake lever of Gear Mechanism Ass’y within 5 seconds.
5After the wire pulled, gear assembly is separated from motor and condition of pulling is held by operation of the
lever.
6When the power is turned off, the drain valve is closed because the wire returns to original position.
