3. DIRECTIONS FOR INSTALLATION AND USE

DIRECTIONS

The openings must not

be obstructed by carpet-

ing when the washing

machine is installed on a

carpeted floor.

■■Installation Of the COVER UNDER (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

2Push the COVER UNDER to

the end. This reduces the

noise from washing machine.

1In the packing box or

the tub of the washer,

there is the COVER

UNDER. Put the

COVER UNDER at the

bottom of the back.

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

vibration may occur.

CONNECTION

FOR ORDINARY TAP

6Connect the inlet hose adapter

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.

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 connector A

tightly. 5Connect the inlet

hose to the water tap

adapter by pulling down

the collar of the hose end.

3Connect the water tap

adapter to the water tap and

tighten the four screws evenly

with 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.

• Check the packing in the inlet

1Connect the inlet

hose to the water tap

by screwing the

connector D tightly. 2Connect the

connector-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

inlet hose.

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.

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

the groove to the guide rib.

Feature of the Washing Machine

1 First applying the Radical Technology in the world ... go beyond washing, sterilize your clothes 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.

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 60

seconds.(But, the SUIT course have no operation of the water currents to adjust the unbalanced load.)

EFFECT

It reduces vibration and noise effectively while spinning.

WATER FLOW

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, the air is dispersed by the

rotation of pulsator. Air-bubble is created by the centrifugal force, and rises up.

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.

channel

Pulsator

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

FUNCTIONAL PRINCIPLE

1. When the lid is closed, the micro 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 is

stopped and rinse process is started

automatically.

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 rotates during the washing

or rinsing process, the water below the

pulsator 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.
