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 CURRENTS TO ADJUST THE UNBALANCED LOAD

It is a function to prevent eccentricity of the clothes after washing by rotating pulsator C.W and C.C.W for 20 seconds.

WATER FLOW

NOTE: "I" mark indicates the operation of the water currents to adjust the unbalance load.

EFFECT

It reduces vibration and noise effectively during spinning.

PULSATOR SYSTEM

When the new shaped pulsator is rotated C.W or C.C.W at a high speed, it makes the 'heart-shaped' water currents as

shown below.

AUTOMATIC DRAINING TIME ADJUSTMENT

This system adjusts the draining time automatically according to the draining condition.

FUNCTIONAL PRINCIPLE

1. The micom can remember the time from the beginning 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 + 60

(T sec.)

WATER CURRENTS

wall by rotation of the pulsator.

SOFTENER DISPENSER

This is the device to dispense the softener automatically by centrifugal force.

This is installed inside the Balancer Ass'y.

FUNCTIONAL PRINCIPLE

1. Softener stays in room (A) when poured into softener inlet.

2. Softener in moved 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 in moved from (C) to (D) by centrifugal 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

NOTE: Softener moves into the next room when r.p.m. of the tub is more than 100 r.p.m.

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.

AUTOMATIC UNBALANCE ADJUSTMENT

This system is to prevent abnormal vibration during intermittent spin and spin process.

FUNCTIONAL PRINCIPLE

1. When the door 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 COURSE AND LINT FILTER

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 vane

creates a water currents as shown in figure.

LINT FILTER

Much lint may be obtained according to the kind of

clothes to be washed and some of the lint may also

stick 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 CLEAN THE 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.

SYNCRONOUS MOTOR

STRUCTURE

FUNCTIONAL PRINCIPLE

1. When the SYNCRONOUS MOTOR connected to the power source the SYNCRONOUS MOTOR rotates 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 is 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.

PRINCIPLE OF INTAKE & OUTLET OF THE AIR

INTAKE : ARMATURE moves up, and BELLOWS inhales the air. At the same time, protector B is open and A is close.

OUTLET: ARMATURE moves down, and BELLOWS exhausts the air. At the same time, protector B is close and A is

open.

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.

FUNCTIONAL PRINCIPLE OF BUBBLE WASHING MACHINE

ACROSS SECTION

FUNCTIONAL PRINCIPLE

HOW TO INSTALL THE WASHING MACHINE

Selection of the Installing Place

Install the washer on the horizontal solid floor.

If the washer is installed on an unsuitable floor, it could make

considerable noise and vibration.

How to install on an Inclined Place

5. DIRECTIONS FOR INSTALLATION AND USE

Never install in these places.

• The place where it would be exposed to direct

sunlight.

• The place nearby a heater or heat appliances.

• The place where it would be supposed to be frozen in

winter.

• The kitchen with coal gas and a damp place like a

bathroom.

1. Height Setting

• After controlling the height by

turning the adjustable leg, let the

washer put down to the ground.

2.

Check the Horizontal Status

• Check the position of tub above

the center of the washer.

NOTES:

The opening must not be

obstructed by carpeting when

the washing machine is in-

stalled on a carpeted floor.

• The proper installation of the washing machine can

increase the wash effectiveness and the life of it.

If the washer is installed on an inclined floor, it could make considerable noise

and vibration and could cause a malfunction.

Use the height adjust rubber to adjust the washing machine so that it sits

properly.

In case that it goes over a

doorsill.

Don't let the height of the

drain hose exceed 20cm

from the gound.

Installing the Drain Hose [Non-pump Model]

¡™

In case of extending the drain

hose.

Don't let the total length

exceed 3m.

Be careful that the end of the

Installing the Drain Hose [Pump Model]

Never forget to install drain hose before operating this

washing machine. The packing box opened, there are a

drain hose, a clamp, and a hose fixture.

Attach the hose guide, included

in the accessory kit, to guide

the drain hose over the tub or

standpipe.

Hook the drain hose to the

edge of the tub, paying

attention that there are no

bends or constractions along

the drain hose.

Or, connect the drain hose to a

standpipe of a diameter greater than

that of the drain hose and at a height

of min. 70cm.

70Cm min

Position the washing machine

next to the wall.

MUST be

ventilated

NOTES:

1. Let the highest point of the drain hose be more than 1m above the floor.

If not so, the water in the washer could be drained during operation

2. Be sure that the height of the drain hose must be less than 1.5m above the floor.

If not so, the water in the washer could not drain.

3. The hose guide MUST be fitted to the drain hose. The drain hose sould not extend more than 55mm from the end of

the hose guide. This is to prevent ‘SYPHONING’.

If necessary the drain hose can be trimmed to length.

Connect the drain hose to the

drain outlet at the rear side of

the washing machine, and

fasten it tightly with the clamp

supplied.

HOW TO GROUND THE WIRE

Grounding Method

• If your water tap or water pipe is

not made of metal, connect the

ground wire to a copper plate or a

metal rod and bury it in the earth.

* It is of no use connecting the

ground wire to the water pipe

made of plastic.

• If both your water tap and water

pipe are made of metal, connect

the ground wire to the base of

the water tap.

• In case of using 3-core cord,

there is no need for grounding.

20Cm

• Never connect it to a gas pipe because of danger of a

explosion. • Never connect it to a telephone wire or a

lightning rod because it is very dangerous at a

thunderbolt.
