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
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 PLA CE
Never install in these places
2
Push the COVER UNDER to the end. This reduces the noise from washing machine.
1
In the packing box or the tub of the washer, there is the COVER UNDER. Put the COVER UNDER at the bottom of the back.
2
Check the Horizon Status
Check the position of tub above the center of the washer.
1
Horizon 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
6
Connect 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.
1
Pull down the collar of the inlet hose to separate it from the water tap adapter.
2
Loosen the four screws at the water tap adapter, but don’t loosen the screws until they are separated from the water tap adapter.
4
Remove the tape, and screw connector B into connector A tightly.
5
Connect the inlet hose to the water tap adapter by pulling down the collar of the hose end.
3
Connect 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
3
Insert the inlet hose adapter into the water inlet of a washer and turn it to be fixed.
• Check the packing in the inlet

CONVENIENCE
CLEANING THE LINT FIL TER
• This washer has two Lint Filters in the top TUB in order to filter off lint and fuzz.
CLEANING THE WATER INLET FILTER
• Clean the filter when water leaks from the water inlet.
3
Return the filter as it was, and insert the filter frame into the slot.
1
Pull the Filter frame upward.
2
Turn the lint filter inside out, wash to the lint off with water.

Feature of the Washing Mac hine
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 35 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 FLO W
Automatic Water Supply System f or Blanket W ash
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

Pulsator
This system is to prevent abnormal vibration during intermittent spin and spin process.
FUNCTIONAL PRINCIPLE
1. When the lid is closed, the contact lever A of the safety switch 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.
10
FEATURE
Much lint may be obtained according to the kind of clothes to be washed and some of the lint may also stick 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 REPLA CE 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.
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
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.
