2. STRUCTURE OF THE WASHING MACHINE The parts and features of your washer are illustrated on this page. Become familiar with all parts and features before using your washer. NOTE • The drawing in this book may vary from your washer model. They are designed to show the different features of all models covered by this book, Your model may not include all features. • Page references are included next to same features. Refer to those pages for more information about the features.
3. FUNCTIONS OF THE CONTROL PANEL Control panel has micom sensor. As the buttons are pressed, the lamps indicating the selection of your desired washing program will light up. HOURS RES. CONTROL PROGRAM • Press this switch to turn the power on or off. • It can be used to choose water temperature to be supplied. • As the button is pressed, water temperature will be repeated. COLD → COLD+HOT → HOT • In case of the single valve model, there is no wash temperature selector function.
4. WASHING PROCEDURE AND PROGRAM SELECTION ■ Full Automatic Program 1. FUZZY PROGRAM (SENSOR); • This selection is for general washing except extraordinary clothes. • Artificial brain sensor selects properly the various kind of washing condition such as washing time, rinse times, spin time and water level. Procedure to press the button; 1 Put in the clothes 2 Press the power switch. 3 Press the Start/Hold button, and close the lid. 2.
4. SUIT(WOOL) PROGRAM; • This selection is effective for suit/wool clothes. (1.2kg’s limitation for 1-time wash) • Do not put leather clothes, or chamios clothes into the washing tub for washing.

MIN MIN HOURS "--" shall blink HOURS adjust to "8" • Now the reservation is made. • If you want to check the selected program, press the “START/HOLD” button again.
5. DIRECTIONS FOR INSTALLATION AND USE ■ Location Of Washer Check location where washer will be installed. Make sure you have everything necessary for correct installation. Proper installation is your responsibility. • Do not place or store your washer below 0˚C(32˚F) to avoid any damage from freezing. • Install the washer on the horizontal sold foor. If the washer is installed on an unsuitable floor, it could make considerable noise, vibrate and cause a malfunction.
■ 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.
■ How To Clean The Filter CLEANING THE LINT FILTER 1 2 Pull the Filter frame upward. 3 Turn the lint filter inside out, wash the lint off with water. Lint Filter Return the filter as it was, and insert the filter frame into the slot. Filter Frame CLEANING THE WATER INLET FILTER • Clean the filter when water leaks from the water inlet. 1 2 Pull the power plug out before cleaning it. 3 Turn off the water supply to the washer and separate the inlet hose. Pull the inlet filter out.
6. FEATURE AND TECHNICAL EXPLANATION Feature of the Washing Machine 1 2 3 4 5 6 The first air bubble washing system in the world. Quiet washing through the innovational low-noise design. The wash effectiveness is much more enhanced because of the air bubble washing system. The laundry detergent dissolves well in water because of the air bubble washing system. The adoption of the water currents to adjust the unbalanced load. One-touch operation system.
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.
Softener Dispenser This is the device to dispense the softener automatically by centrifugal force. This is installed inside the auto-balancer. FUNCTIONAL PRINCIPLE 1 2 3 4 Softener stays in room (A) when poured into softener inlet. Softener moves from (A) to (B) by centrifugal force during intermittent spin process. Softener flows from (B) to (C) during rinse process next to intermittent spin. Softener moves from (C) to (D) by centrigfugal 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 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.
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. Filter Filter Bleach Inlet Bleach Inlet Pulsator Pulsator HOW TO REPLACE LINT FILTER 1 Pull the filter frame upward.
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. Pulsator shaft Spin shaft One way clutch bearing Gear unit as Sun gear Internal gear Planetary gear Clutch spring Brake lever Clutch boss Gear pulley Motor Pulsator 1490 r.p.m (50Hz) Gear unit as 1 revolution Motor Pulsator Gear Unit as Gear Pulley 5 revolutions 138 r.p.m 720 r.p.m Tub Gear pulley Directly 720 r.p.
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 opend. 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.
7. DIRECTIONS FOR DISASSEMBLY AND ADJUSTMENT Warning BEFORE ATTEMPTING TO SERVICE OR ADJUST ANY PART OF THE WASHING MACHINE, DISCONNECT THE POWER CORD FROM THE ELECTRIC OUTLET. Gear Mechanism Ass’y Replacement ● Raise the top plate on the outer cabinet. ● Remove outer tub cover from the tub ass’y. ● Loosen the pulsator mounting screw and remove ● Remove the spinner shaft flange nut by using ‘T’ ● Remove the tub ass’y. type box wrench.
● Lay the front of the washer on the floor. ● Remove four bolts mounting the plate-gear protect by ● Remove four bolts mounting the gear mechanism ass’y by using a box wrench. using a box wrench and remove plate-gear protect. ● Remove the V-belt. ● Pull out the gear mechanism assy.
Motor Synchronous And Valve Replacement(Non Pump Model) ● Lay the front of the floor. ● Loosen two special screw and motor synchronous. ● Take out the wire of motor synchonous from the bracket. ● Separate the motor sycnchronous from the base. ● Turn the valve by using screw driver as shown in picture. ● Remove the valve lid from the valve drain assy. Brake Adjustment ● Loosen the adjustment bolt and turn the adjustment bolt until the end of the bolt touches to the brake lever.
