How To Install On An Inclined Place

¡The place where it would be exposed to

direct sunlight.

¡The place nearby a heater or heat appli-

ance.

¡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

2Push the noise insulation plate

into the end, which decrease

the noise made by this washer.

1The packing box

opened, there is a

noise insulation plate

at the bottom of the back

(DWF-7094, 8094) or front

(DWF-1094).

2Check the Horizon

Status

Check the position of tub above

the center of the washer.

1Horizon

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 vibra-

tion may occur.

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 puling down

the collar of the hose end.

3Connect the water tap

adapter to the water tap tight-

en 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 TAP 3Insert the inlet hose adapter

into the water inlet of a washer

and turn it to be fixed.

• Assert the packing in the inlet

1Connect the inlet

hose to the water tap

by screwing the con-

nector D tightly. 2Connect the connec-

tor-inlet supplied if

necessary.

How To Clean The Filter

Remove the dirt

from the inlet filter

with a brush.

Pull the

power plug

out before

cleaning it.

Turn off the

water supply

to the washer

and sperate the

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 cack 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 to

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

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

Function for Soak Wash

DISPLAY THE RESIDUAL TIME

When the SOAK WASH is selected, the total wash time increases because 60 minutes for soak process are added

to the time of main process.

PROGRESS

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

30 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.

‘ ’ mark indicates the operation of the water currents to adjust the unbalanced load.

NOTES

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 + 90 Residual drain time.

The time remembered by micom.

Asymmetrically designed pulsator

makes the cyclone water fow, which get

rid of the washing dead zone to

increase the washing effect and reduce

the entanglement of laundry.

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.

Drain Time Movement of the Program

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.

Automatic Drainning time Adjustment

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

NOTES

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 auto-

matically 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.

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.
