PROCEDURE 7
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.
§èINSTALLATION OF THE UNDER BASE COVER [OPTION]
-DWF-5510/5511/5010/6011
1Before 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.
2Push the under-base cover into the end, which decrease the noise made by this washer.
SCREW
-DWF-5520/5521/6020/6021
1There is under-base cover in the tub of the washer. Put out and draw it in its proper site. (See picture)
2Push the under-base cover into the end, which decrease the noise made by this washer.

6. FEATURE AND TECHNICAL EXPLANATION
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.

* 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 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.

SOFTENER DISPENSER
This is the device to dispense the softener automatically by centrifugal force.
This is installed inside the auto-balancer.
FUNCTIONAL PRINCIPLE
1Softener stays in room (A) when poured into softener inlet.
2Softener moves from (A) to (B) by centrifugal force during intermittent spin process.
3Softener flows from (B) to (C) during rinse process next to intermittent spin.
4Softener 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.

AUTOMATIC UNBALANCE ADJUSTMENT
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 automatically 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.

NOTES

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.
