2. 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.
PULSATOR SYSTEM When the new shaped pulsator is rotated C.W or C.C.W at a high speed, it makes the 'heart-shaped' water currents as shown below. C WATER CURRENTS A Water is pushed up near the tub wall by rotation of the pulsator. Rotate B Water is pulled down in the middle of the tub by rotation of the pulsator B A C Water currents is generated by rotation of the pulsator. A AUTOMATIC DRAINING 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 Balancer Ass'y. FUNCTIONAL PRINCIPLE 1. Softener stays in room (A) when poured into softener inlet. 2. Softener in moved 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 in moved from (C) to (D) by centrifugal force during second intermittent spin.
AUTOMATIC UNBALANCE ADJUSTMENT This system is to prevent abnormal vibration during intermittent spin and spin process. FUNCTIONAL PRINCIPLE 1. When the door 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.
LINT FILTER 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. Bleach inlet Filter Pulsator HOW TO CLEAN THE LINT FILTER 1. Pull the filter frame upward. 2. Turn the lint filter inside out, and wash the lint off with water. 3.
GEAR MECHANISM ASS'Y The proper water currents is made by the rotation of pulsator at a low speed to prevent the damage to the small sized clothes.

PRINCIPLE OF INTAKE & OUTLET OF THE AIR INTAKE : ARMATURE moves up, and BELLOWS inhales the air. At the same time, protector B is open and A is close. OUTLET: ARMATURE moves down, and BELLOWS exhausts the air. At the same time, protector B is close and A is open. FUNCTIONAL PRINCIPLE OF TRANS & MAGNET • The phase of A.C electric power changes to 60 cycle/second. • The magnetic pole of trans core is changed by the change of the phase of A.C electric power. • The core repeats push and pull (3600 times/min.

5. DIRECTIONS FOR INSTALLATION AND USE HOW TO INSTALL THE WASHING MACHINE Selection of the Installing Place Install the washer on the horizontal solid floor. If the washer is installed on an unsuitable floor, it could make considerable noise and vibration. Never install in these places. • The place where it would be exposed to direct sunlight. • The place nearby a heater or heat appliances. • The place where it would be supposed to be frozen in winter.
¡ Installing the Drain Hose [Pump Model] Never forget to install drain hose before operating this washing machine. The packing box opened, there are a drain hose, a clamp, and a hose fixture. the hose guide, included ™ Attach in the accessory kit, to guide the drain hose over the tub or standpipe. £ Hook the drain hose to the edge of the tub, paying attention that there are no bends or constractions along the drain hose.
HOW TO CONNECT THE INLET HOSE In Installing the Inlet Hose ¡ Pull down the collar of the inlet hose to separate it from the water tap adapter. ™ Water Tap Adapter Loosen the four screw at the water tap adapter, but don't loosen the screws until they are separated from the water tap adapter.
HOW TO GROUND THE WIRE Grounding Method • If your water tap or water pipe is not made of metal, connect the ground wire to a copper plate or a metal rod and bury it in the earth. 20Cm • If both your water tap and water pipe are made of metal, connect the ground wire to the base of the water tap. • In case of using 3-core cord, there is no need for grounding. * It is of no use connecting the ground wire to the water pipe made of plastic.

• The Electrolytic condenser C22(1000µF, 16V) and diode D5 is used in order that at instant power supply failure circuit should remember the contents of the program. It happens that the MICOM terminal No. 42 has instant interruption of electric power, yet the MICOM is not discharged electricity because of the diode D5. • The measurement of voltage EFFECTIVE VALUE ! @ # $ % 82.5V 5.2V 7.9V 7.9V 5.97V 5.4V 119V 7.2V 11V 11V 5.97V 5.4V 137.5V 9.3V 14.1V 14.1V 5.98V 5.4V 165V 5.3V 7.
• After connecting the part of the dotted line & waveform measurement • The waveform measurement in the MICOM No.37. 5.4V 0V 0V The waveform of the secondary part in transformer passes through the diode D1,D4 (1N4003), and then the voltage is divided by means of the resistance R60 & R61. This voltage gives force to input the pulse to the MICOM terminal No. 37 on the ground of action of the TR Q6 (C3202Y). 3.

If the oscillation doesn’t generate, we are able to consider that the MICOM is destroyed. • The waveform between the part of ! and the GND. f = 4.194304 MHz t • Specification of oscillator It is in general use for the MICOM maker's recommendatory value of condenser which is fit for MICOM's characteristics.
2. EXPLANATION OF CIRCUIT • The MICOM terminal No. 13 gets into 'L' at the state of the closed door. If the door is opened in spining stage, the MICOM generates error signal. (See page 27) • Case of range 40 mSEC~300 mSEC in spining time: It is regarded that washing clothes should be inclined. Accordingly washing time increases 8 minutes and rinsing action takes place another one time. Case of above 400 mSEC: It is regarded that the door should be open. Therefore it is displayed as door open error.
