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 in 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 20 seconds. (But, the DRY & SILK course have no operation of the water currents to adjust the unbalanced load.) EFFECT It reduces vibration and noise effectively while spinning.

FUNCTION FOR SOAK WASH
DISPLAY THE RESIDUAL TIME When the SOAK WASH is selected, the total wash time increases because 30 minutes for soak process are added to the time of main process. PROGRESS SOAK PROCESS FILL · WASH 2' I STOP 8' WASH 2' I STOP 8' WASH 2' I STOP 8' MAIN PROCESS
30 Minutes NOTE: ` I ' mark indicates the operation of the water currents to adjust the unbalanced load.
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 30 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 DRAINING TIME ADJUSTMENT
This system adjusts the draining time automatically according to the draining condition. Good draining Draining condition Bad draining No draining The washer begins spin process after drainage. Draining time is prolonged. Program is stopped and gives the alarm.
FUNCTIONAL PRINCIPLE 1) The micom can remember the time from the beginning of drain to reset point when the pressure switch reaches to "OFF" point. Drain Time Less than 4 minutes More than 4 minutes Continue draining. Program stops and gives the alarm with the 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 + 60 (T sec.) Residual drain time. The time remembered by micom.

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 centrifugal 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.

NOTE: The alarm finished when you close the lid after opening it. Check the unbalance of the wash load and the installation condition.
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 40L/min. water is circulated at the 'high' water level, standard wash load and standard water currents.
Tub Filter Water channel Pulsator Outer tub

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.

2) EXPLANATION OF CIRCUIT · The MICOM terminal No. 33~40 amplifies the source current to produce the 'H' by use of the buffer UDN-2981A. And the MICOM terminal No. 43~54 sufficiently amplifies the sink current by use of the DRIVE I.C. ULN-2004A. · The waveform between the part of ! and the GND (part of the DUTY).
5.4V 0V 3.085 mSEC t
The division rate of the DUTY is 1/9. And as part of the DUTY treats the black time between the square waves, it prevents the phenomenon of faint lighting of L.E.D unnecessarily due to the phenomenon of fold in delay time of the IC 8 between the input and the output. · The equivalent circuit of DRIVE IC & BUFFER IC.
