step 1. Press power switch. step 2. Press program button until the indicating lamps make the combinations you want.

If only spin lamp is turned on, that means you will operate your washer for spin only. If rinse and spin lamp are turned on, that means you will operate your washer for rinse and spin. If add lamp is turned on with other porcess lamps, that means the time of the corresponding porcess will increase by 1~2 minutes, that is, if add is on with wash, rinse and spin, the time of each precess will increase

by 1~2 minutes. (Wash: add 2 min., Rinse: add 1 min., Spin: add 1 min.) step 3. Press water level selector as your decision. step 4. Press Start/Hold to start.

5. DIRECTIONS FOR INSTALLATION AND USE

SCREW

Installing Place

Install the washer on a horizontal solid floor. If the washer is installed on an unsuitable floor, it could make considerable noise and vibration.

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

Installation Of The Under Base Cover [Option]

vibration may occur.

-DWF-5510/5511/5010/6011

Never install in these places

¡ The place where it would be

exposed to direct sunlight.

¡ The place nearby a heater or heat

appliance.

¡ The place where it would be sup-

posed to be frozen in winter.

¡ The kitchen with coal gas and a

damp place like a bathroom.

1 Before installing your

washer, remove the pad from the bottom of the cabinet. Then, separate under cover from rear side of cabinet by unscrewing and insert it into the base.

2 Push the under-base

cover into the end, which decrease the noise made by this washer.

-DWF-5520/5521/6020/6021

1 There is under-base

cover in the tub of the washer. Put out and draw it in its proper site. (See picture)

§§

How To Install On An Inclined Place

2 Push the under-base

cover into the end, which decrease the noise made by this washer.

Horizon

Setting

After controlling the height by turning the adjustable leg, let the washer put down to the ground.

DIRECTIONS

Check the Horizon

Status

Check the position of tub above the center of the washer.

NOTES

The openings must not be obstructed by carpeting when the washing machine is installed on a carpeted floor.

6. 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.

* When the water level is “HIGH”

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 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

Pulsator System

When the pulsator is rotated C.W or C.C.W at a high speed, it makes the cyclone water flow from the asymmetrically designed pulsator as shown below.

Asymmetrically designed pulsator makes the cyclone water flow, which get rid of the washing dead zone to increase the washing effect and reduce the entanglement of laundry.

Automatic Drainning time Adjustment

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

Draining condition

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

Drain Time Movement of the Program

Less than

10 minutes

More than

10 minutes

2 In case of continuous draining, residual drain time is determined by micom.

Draining time as a whole = D + 30

Good draining The washer begins spin process after drainage. Bad draining Draininig time is prolonged. No draining Program is stopped and gives the alarm.

Continue draining

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

Residual drain time. The time remembered by micom.

EXPLANATION

Softener Dispenser

This is the device to dispense the softener automatically by centrifugal force. This is installed inside the auto-balancer.

FUNCTIONAL PRINCIPLE

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.

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.

EXPLANATION

Automatic Unbalance Adjustment

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

FUNCTIONAL PRINCIPLE

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 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 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.
