§ è 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 ORDINARY TAP
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.

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. WATER FLOW

Automatic Water Supply System
The water level would be lowered because the clothes 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.

Automatic Drainning time Adjustment
This system adjusts the draining time automatically according to the draining condition. Good draining Draining Bad draining condition No draining Program is stopped and gives the alarm. Draininig time is prolonged. The washer begins spin process after drainage.
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 Drain Time Less than Continue draining 10 minutes More than Program stops and gives the alarm with 10 minutes blinked on display lamp. Movement of the Program
2 In case of continuous draining, residual drain time is determined by micom. Draining time as a whole = D + 40 Residual drain time. The time remembered by micom.

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.

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.
NOTES The alarm finished when you close the lid after opening it. Check the unbalance of the wash load and the installation condition.
Circulating-Water
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.
Filter Tub Water channel Pulsator
Outer tub

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.

Pull Loosen Pulley Lever Inductive ring Magnet
Coil of motor Magnet of motor
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.

How To Check The Clutch Spring Problem
PROBLEM 1) THE LAUNDARY IS IN THE SPIN TUB UNEVENLY WHEN JUST STARTING SPIN PROCESS. 2) THEREFORE, IT CAUSE THE SERIOUS NOISE AND VIBRATION WHEN WASHING AND SPINNING PROCESS OR SUPPLING WATER IRREGULARY WHEN SPINNING PROCESS AND CAUSE SHORT OF SPIN PERFORMANCE.
CHECKING METHOD IN THIS CASE, YOU MUST EMPTY THE SPIN TUB FIRST. 1) TO CHECK THE REVOLUTION OF SPIN TUB. IF THE SPIN TUB DOES NOT REVOLVE AND ONLY THE PULSATOR IS TURNING, THAT IS CLUTCH SPRING DEFECT. 2) TO CHECK THE SPIN SPEED(RPM) BETWEEN SPIN TUB AND PULSATOR. IF YOU FIND THE DIFFERENT SPIN SPEED BETWEEN SPIN TUB AND PUSATOR, THIS IS ALSO CLUTCH SPRING DEFECT. IN THIS CASE, WE ARE GOING TO SUPPLY THE CLUTCH BOSS ASSEMBLY INSTEAD OF GEAR MECHANISM ASSEMBLEY. PLEASE REFER TO FOLLOWING FIG.

9. PRESENTATION OF THE P.C.B ASS'Y
Concerning Error Message
MESSAGE CAUSE Improper installation of drain hose. The drain hose is blocked up by foreign matter. Drain motor is inferior. The water tap is closed. The water inlet filter clogged. It passes over the 30 minutes, yet it doesn't come to assigned water level. Wash loads get uneven during spin. Poor installation of the unit. The lid is opened. The safety switch is inferior. The load sensing is inferior. After the load sensing operates about 7 seconds, the message is displayed during 1 second and water level is always fixed `high'. SOLUTION Install drain hose properly. Remove foreign matter from drain hose.
Change drain motor. Open the water tap. Clean the water inlet filter. Check whether or not is comes to the assigned water level. Re-set wash loads evenly. Proper installation. Close the lid. Change the safety switch.
Change the P.C.B. ASS'Y.
The water level sensing is inferior.
Check the water level sensor and the contact part of the connector.
