4. DIRECTIONS FOR INSTALLATION AND USE

§

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.

UP DOWN

A

C

B

If the washer is installed on an unsuitable floor, it could make considerable noise, vibrate and cause a malfunction.

If washer is not level, adjust the front leg(A) up or down for horizontal setting.

• 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/cm 2 -

8kgf/cm 2 (2.94N/cm 2 -78.4N/cm 2 ).

§

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.

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 ORDINARY TAP

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.

3 Connect 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.

How To Clean The Filter

CLEANING THE LINT FILTER

1 Pull the Filter frame upward.

2 Turn the lint filter inside out, wash the lint off with water.

3 Return the filter as it was, and insert the filter frame into the slot.

Lint Filter Filter Frame

CLEANING THE WATER INLET FILTER

• Clean the filter when water leaks from the water inlet.

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.

4

Remove the dirt from the inlet filter with a brush.

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.

1 Put down the remained water in the hose. And put a container under the filter to collect water.

2 Turn the cap counterclockwise.

5. FEATURE AND TECHNICAL EXPLANATION

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.

• • • • • • •

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 selected water level is reached.

EXPLANATION 9

Automatic Drainning time Adjustment

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

Draining condition

Good draining

Bad draining

No draining

The washer begins spin process after drainage.

Draininig time is prolonged.

Program is stopped and gives the alarm.

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

Movement of the Program Drain Time

Less than

10 minutes

More than

10 minutes

Continue draining

Program stops and gives the alarm with blinked on display lamp.

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.

10 EXPLANATION

Softener Dispenser

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

This is installed inside the auto-balancer.


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.

EXPLANATION 11

Automatic Unbalance Adjustment

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


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.

NOTES

The alarm finished when you close the lid after opening it. Check the unbalance of the wash load and the installation condition.

Circulating-Water

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.

Lint Filter

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.

Inlet

HOW TO REPLACE 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.

Residual Time Display

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.

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.

EXPLANATION 13

1) THE LAUNDARY IS IN THE SPIN TUB UNEVENLY WHEN JUST STARTING SPIN PROCESS.

2) THEREFORE, IT CAUSE THE SERIOUS NOISE AND VIBRATION WHEN WASHING AND SPINNING

PROCESS OR SUPPLING WATER IRREGULARY WHEN SPINNING PROCESS

AND CAUSE SHORT OF SPIN PERFORMANCE.

CHECKING METHOD

IN THIS CASE, YOU MUST EMPTY THE SPIN TUB FIRST.

1) TO CHECK THE REVOLUTION OF SPIN TUB. IF THE SPIN TUB DOES NOT REVOLVE AND ONLY

THE PULSATOR IS TURNING, THAT IS CLUTCH SPRING DEFECT.

2) TO CHECK THE SPIN SPEED(RPM) BETWEEN SPIN TUB AND PULSATOR.

IF YOU FIND THE DIFFERENT SPIN SPEED BETWEEN SPIN TUB AND PUSATOR, THIS IS ALSO
