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. WATER FLOW WASH DRAIN MOTOR C.W SINGAL C.C.W TIME(SEC.) SPIN FILL 0.4 0.4 RINSE 1 0.4 DRAIN SPIN FILL RINSE 2 0.4 0.4 0.4 ••••••• DRAIN ••• 40 SEC. (About 25 Times) * When the water level is “HIGH” 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. EXPLANATION 9 Automatic Drainning time Adjustment This system adjusts the draining time automatically according to the draining condition. Good draining The washer begins spin process after drainage. Bad draining Draininig time is prolonged. No draining Program is stopped and gives the alarm. Draining condition 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 Movement of the Program Less than Continue draining 10 minutes More than Program stops and gives the alarm with blinked on display lamp. 10 minutes 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. 10 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. FLOW OF THE SOFTENER Wash Normal Program Intermittent Spin Centrifugal force (A) Hold Intermittent Spin Rinse Flow in Centrifugal force Flow in (B) (C) Spin (D) FLOW OF THE SOFTENER INSIDE OF THE BALANCER Room inside the balancer A B C D Centrifugal force Flowing by weight NOTES Softener moves into the next room when r.p.m of the tub is more than 100 r.p.m. 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. Balancer Softener outlet B A D C Softener inlet EXPLANATION 11 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. 12 EXPLANATION Filter Tub 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.

- Prevents unbalancing during the spin cycle
- Reuses water to minimize consumption
- Filters lint and particles from the wash water
Frequently asked questions
The automatic water supply system uses sensors to determine the size and type of load, and then adjusts the amount of water used in the wash cycle accordingly.
The automatic draining time adjustment system ensures that all of the water is drained from the machine before the spin cycle begins, which helps to prevent mold and mildew growth.
The automatic unbalance adjustment system uses sensors to detect when the machine is unbalanced during the spin cycle, and then adjusts the spin speed to correct the imbalance.
The circulating-water system reuses water from the previous wash cycle to reduce water consumption.
The lint filter traps lint and other small particles from the wash water, preventing them from redepositing on the clothes.
