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. 2 3 PULSATOR SYSTEM SOFTENER DISPENSER 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. This is the device to dispense the softener automatically by centrifugal force. This is installed inside the auto-balancer. C 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. WATER CURRENTS A Rotate B B A A C Water is pushed up near the tub wall by rotation of the pulsator. Water is pulled down in the middle of the tub by rotation of the pulsator. Water currents is generated by rotation of the pulsator. FLOW OF THE SOFTENER Wash AUTOMATIC DRAINING TIME ADJUSTMENT Normal This system adjusts the draining time automatically according to the draining condition. 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.

NOTE : Softener moves into the next room when r.p.m of the tub is more than 100 r.p.m. 4 minutes 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 outler. 2) In case of continuous draining, residual drain time is determined by micom. Draining time as a whole = D + 60 Residual drain time. The time remembered by micom. (T sec.)

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. FUNCTIONAL PRINCIPLE 1) Always 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. Contact of safety switch Filter Bleach Inlet Pulsator 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. Contact lever A Position of unbalanced load (OFF) RESIDUAL TIME DISPLAY Normal (ON) NOTE: The alarm finished when you close the lid after opening it. Check the unbalance of the wash load and the installation condition. When the START/HOLD button is pressed, the residual time (min.) is displayed on the time indicator, and it will be counted down according to process. When operation is finished, the TIME INDICATOR will light up . DRAIN MOTOR STRUCTURE 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 40 L/min. water is circulated at the ‘high’ water level, standard wash load and standard water currents. Pull Loosen Pulley Lever Tub Inductive ring Magnet Filter Outer tub Coil of motor Magnet of motor Water channel Pulsator FUNCTIONAL PRINCIPLE 1) When the DRAIN MOTOR connected to the power source(A.C 220V), 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. 6 7 GEAR EMCHANISM ASS’Y The proper water currents is made by the rotation of pulsator at a low speed (about 140 r.p.m) 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 opend. Pulsator shaft FUNCTIONAL PRINCIPLE OF TRANS & MAGNET The phase of A.C electric power changes to 60 cycle/second.

Therefore the value of R43 was decided to 51.5 KΩ, F(1%). • C15 used electrolytic condensor (1µF) to remove noise and to stabilize the voltage. • EEPROM PIN FUNCTION PIN NAME CS 3) CAUTION FOR A/S 1. HOW TO CHECK TEMPERATURE SENSOR.( Reference to TEST MODE) If the L.E.D displays ‘LO’ or ‘HI’, there is some trouble with the temperature sensor. In this case, the processing is designed to perform normal processing. Before change temperature sensor, check the connector and temperature sensor. 2. There is function to give up role of temperature sensor forcibly. At the first condition in TEST MODE press the RESERVATION button. And after change data by SOAK button, press START/HOLD button. If so, data input. (11 : perform to temperature sensor, 22 : give up temperature sensor) CLK FUNCTION Chip selector Chip is enabled when CS is at ‘L’ level. Set CS to ‘H’ level before executing instruction. Clock input The DI data is latched at the rising edge of CLK. The data is out from DO at the falling edge of CLK. CLK is enable when CS is at ‘L’ level. DI Serial data input The address, command and data input pin. DO Serial data output The data output pin 3. In the FUZZY course (WASH:14min, RINSE : 2Times, SPIN:5min, COOL WATER SELECTION) the total processing time can be changed by water temperature. ORG RDY/BUSY Organization select The 16-bit organization is selected when ORG is ‘H’ level. The 8-bit organization is selected when ORG is ‘L’ level. Status output ‘L’ level is output during program or chip eraise operation. ‘H’ level is output when program or chip eraise operation is completed. EEPROM stores the selected contents in MEMORY course and LOAD SENSING data. If you press MEMORY button, MICOM read the contents in MEMORY course and L.E.D displays the selected contents in MEMORY course. 3) CAUTION FOR A/S 1. When the selected contents of MEMORY course in EEPROM can not memorize, EEPROM is defective. 42 43 APPENDIX WIRING DIAGRAM TEMP SENSOR BR or VT VT BL C MOTOR 1 2 3 DRAIN MOTOR VT BL BL/YW WH BL/YW 15µH BL/YW VT VT VT 2 BK 15µH 3 L/F BL BL BL BL/YW BL/YW 1 WH A 4 4 FUSE RD/BL RD/BL 3 BL/YW BL/YW 5 BL/.YW 2 1 2 1 2 VT 1 2 1 2 1 2 3 2 1 2 1 2 1 VT BL 6 YW YW WH/RD 1 BR or VT WATER LEVEL S/W SAFETY S/W VT B COLD WS VALVE RD/BL VT HOT W/S VALVE WH WH/RD 1 9 8 7 7 WH/RD Repeat drive without “off” in “d2” 45 POWER CORD BK GN WH AC SOURCE EARTH • RATING : REFER TO RATING PLASTE • RESIN MOTOR • BRACKET MOTOR GN 11.4µF 240 230 220 41.6µF 12.5µF or R 13.5µF B 12.5µF or 13.5µF 12.5µF B 54µF 127 C B 110 600mA 315mA OR 300mA R 50µF 100~127 220~240 250V/4A OR 5A 220~240 A SPEC 250V/8A RATING (V) 100~127 SYMBOL F-P.C.B.
