Installation Of The 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
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.
FOR SCREW-SHAPED T A P
3
Insert the inlet hose adapter into the water inlet of a washer and turn it to be fixed.
• Check 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 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.
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
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.
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 Agitator, the air is dispersed by the rotation of Pulsator Agitator. Air-bubble is created by the centrifugal force, and rises up.
Draining
Good draining The washer begins spin process after drainage.

NOTES
Tub

Pulsator Agitator
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 Agitator rotates during the washing or rinsing process, the water below the Pulsator Agitator 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.
10
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 in the center of pulsator agitator 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 cap agitator 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 lint into the pulsator agitator.
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.
