5. DIRECTIONS FOR INSTALLATION AND USE
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.
10Cm
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.
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 supposed to be frozen in winter.
¡ The kitchen with coal gas and a damp place like a bathroom.

Installation Of The Under Base Cover [Option]
-DWF-5510/5511/5010/6011
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.
SCREW
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)
2 Push the under-base cover into the end, which decrease the noise made by this washer.

How To Install On An Inclined Place
1 Horizon
Setting
After controlling the height by turning the adjustable leg, let the washer put down to the ground.
2 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.

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 11
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
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 + 30
Residual drain time.
The time remembered by micom.
12 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.

EXPLANATION 13
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.

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.

14 EXPLANATION
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.

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.

FUNCTIONAL PRINCIPLE
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 15
Gear Mechanism Ass’y
The proper water currents is made by the rotation of pulsator at a low speed to prevent the damage to the small sized clothes.

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