4. INSTALLATION Before servicing ask troubles of customers Check the adjustment(power supply is 220-240V, remove the transit bolts...) Check the troubles referring to the trouble shooting. Decide service steps referring to disassembly instructions. And then, service and repair. After servicing, operate the appliance whether it works O K or NOT. STANDARD INSTALLATION The appliance should be installed as follows. REMOVE THE TRANSIT BOLTS Remove the transit bolts (4EA: )with supplied spanner. Keep the transit bolts and spanner for future use. INSTALL THE APPLIANCE ON FLAT AND FIRM SURFACE ADJUST THE HORIZONTAL Turn the leveling feet to set the appliance horizontally. Low High The appliance goes up by rotating the feet clockwise. The appliance come down by rotating the feet counter clockwise. 1 8 HOW TO CONNECT INLET HOSE Check that the rubber packing is inside of the valve connector. Connect the inlet hose firmly to prevent leak. CONNECT DRAIN HOSE Make sure that the hose is not twisted. Avoid submerging the end of the hose. The drain hose should be placed under 85 CONNECT POWER PLUG from the floor. Connect the power plug to the wall outlet. Avoid connecting several electric devices, It may be the cause of the fire. 9 TEST OPERATION Preparation for washing. Press the power button. Press the START/PAUSE button. START PAUSE Connect the power plug to the outlet. Connect the inlet hose. In case of Coloreds program. Check the water heating. Check automatic reverse turn. Check the water supply. Check if the drum rotate to clockwise and counterclockwise. Check if water is supplied through the detergent dispenser. Check the drain and spin Power off Water removal 800 (1000) 600 (800) no Spin (600) SPIN Door Open After power off, press the DOOR OPEN button to check the door open. If SVC is needed, during check and remove the remaining water by pulling out the hose cap.

2-2.SENSING THE LAUNDRY AMOUNT PRINCIPLE : After the first water supply, the laundry absorbs the water with the revolution of drum, which causes the decrease of water level. Micro-Processor senses decreased water level and makes water to be supplied more and recognizes he amount of the laundry by calculating the times of complementary water supply. Criteria : AMOUNT OF LAUNDRY below 2.0 above 4.5 TIMES OF COMPLEMENTARY WATER SUPPLY 1~2 times 3 times or more The times of water supply depends on amount of laundry, material of laundry and water temperature etc. 2-3.DETERMINE WASHING TIME BY FUZZY LOGIC To get the best washing performance optimal time is determined by sensing of water temperature, selected washing temperature and laundry amount. water temperature washing time selected washing temperature FUZZY LOGIC rinse time spin rhythm, time the best washing performance laundry amount SENSING PROCESSING DETERMINATION EFFECT 2-4.WATER LEVEL CONTROL This model adopts a pressure sensor which can sense the water level in the tub. When the water level reaches to the preset level water supply is stopped, then washing program proceeds. Spinning does not proceed until the water in the tub reduces to a certain level. 5 2-6.THE DOOR CAN NOT BE OPENED While program is operating. While Door Lock light turns on. 2-7.WHEN DOOR LOCK LIGHT TURNS ON Water level frequency is below 23.2kHz.(Water level is high) Water temperature in the tub is above 45 6

7. TROUBLE SHOOTING 7-1.BEFORE SVC CHECKING Be careful of electric shock while trouble shooting. Disconnect power plug from the outlet before service. 7-2.TEST MODE. If you press Power button with both Rinse and Spin buttons pressed the machine can be gotten into the test mode. To check if functions operate well, press Start/Pause button in test mode as follows. NOTE : Even if you press the button to check inlet valve, inlet valve does not operate until the drum comes to a complete stop from spinning. Times of press None 1 time 2 times 3 times 4 times 5 times 6 times 7 times 8 times 9 times 10 times Checking Point All lamps turn on Counterclockwise spin Low speed Spin High speed Spin Inlet valve for pre-wash operation Inlet valve for main-wash operation Inlet valve for main-wash operation Clockwise spin The Heater is in operation for 3 sec.
