FEATURES & TECHNICAL EXPLANATION 2-1. FEATURES Anti Crease function With the alternate rotation of the drum, creasing in the laundry is minimized. More economical by Fuzzy Logic System FUZZY Logic System detects the amount of load and water temperature, and then determines the optimum water level and washing time to minimize energy and water consumption. Child-Lock The Child-Lock system has been developed to prevent children from pressing any button (except Power button) to change the programme during operation. Low noise speed control system By sensing the amount of load and balance, this system automatically distributes load evenly to minimize the spinning noise level. Direct Drive System The advanced Brushless DC motor rotates the drum directly without a belt and a pulley. Built-in heater Internal heater automatically heats the water to the best temperature on selected cycles. 4 2-2. 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 the best washing performance spin rhythm, time laundry amount SENSING PROCESSING DETERMINATION EFFECT 2-3. WATER LEVEL CONTROL This model uses a pressure sensor to determine the water level in the tub. When the preset water level reached, water supply is stopped and the program proceeds. W ater needs to be below a preset level before spining will proceed. 2-4. THE DOOR CAN NOT BE OPENED While program is operating. While Door Lock light turns on. 5 3.

INSTALLATION INSTALLATION The appliance should be installed as follows. 1 Check the conditions of installation area. 1. Check level ground. horizontal On raised foundations or upper level homes, the vibrations can be caused by the type of flooring. It may be necessary to move the machine to a different area in the home or have the floor reinforced to properly support the operation of the unit. 2. Check humidity or any foreign objects under the feet. Clean the floor, and there should not be any foreign objects under the feet. If the unit has foreign objects underneath the feet, this will prevent the unit from being leveled properly and will cause vibrations and slipping . Remove any foreign objects , if any from underneath the machine and level unit properly. See below for examples of foreign objects. Purchased stopper Capet Paper Laminated paper 2 Open the box and check appliance condition. Washer Base Packing Packing Support Wrench 7 This leveling (or spanner) wrench must be used to remove the shipping bolts and level the unit. This should be kept for future use. 3 Use spanner to remove transit bolts. X 4 EA Without removal of transit bolts Spin noise and shaking . Transit bolts 4 Confirm the distance between the appliance and the wall. If the distance is less than 2cm, the water supply hose will kink or fold . More than 2cm 5 The tap connection and hose connection must be parallel. 1. Normal Tap without thread & screw type inlet hose. 1. Unscrew the fixing screw to attach the tap. Upper Connector 2. Push the connector up till the rubber packing is in tight contact with the tap. Then tighten the 4 screws. Rubber packing 3. Push the water supply hose vertically upwards so that the rubber packing within in the hose can adhere completely to the tap and then tighten it by screwing it to the right. Rubber packing Upper Connector Upper Connector Plate Fixing screw Water supply hose 2. Normal Tap without thread & one touch type inlet hose (Single inlet models) 1. Untighten the upper connector screw. Upper Connector Rubber packing 2. Push the upper connector up till the rubber packing is in tight contact with the tap. Then tighten the 4 screws. Middle connector • In case the diameter of the tap is large remove the guide plate. Guide plate to the middle connector, pushing the plate down. Upper Connector Rubber packing Fixing screw 3. Connect the water supply hose Upper Connector Plate Water supply hose Middle connector • Turn the middle connector not to have water leaked. • Make sure that the rubber seal is inside the hose connector. • To separate the water supply hose from the middle connector shut off the tap. Then pull the inlet hose down, pushing the plate down. Connector Hose connector Rubber seal 8 • Make sure that there are no kinks in the hose and that it is not crushed. 6 Connect Drain Hose. If the drain hose is not installed properly, the unit will not drain properly. This allows water to back flow into the unit which can cause odors. Refer to Owner Manual for proper drain hose installation. The odor could also be coming from the home’s drain to which the drain hose is attached. Laundry tub about 100 cm Hose Retainer Tie strap max. 100 cm about 105 cm min. 60 cm about 145 cm Max. 100cm min. 60cm Max. 100cm min. 60cm In this type of drain hose installation, the odor could be coming from the standpipe. This odor can come up the drain hose and into the unit. Pour a cup or two of bleach or vinegar down the home drain and let it sit for 24 hours before running another cycle. This will help eliminate odor from the home drain. If a cycle is started too soon after doing this, it will not help the issue. 7 Connect power plug. Connect the power plug to the wall outlet. Avoid connecting several electric devices, it may be the cause of a fire. 9 8 Check the horizontality with a level (Gage). 1 Step If washing machine legs are loose or not screwed, then screw up with the spanner wrench. Using the level, level the washing machine from front to back and side to side. A level Higher Tighten Adjustable feet 2 Step Using the spanner wrench to adjust leg for horizontality and try for Diagonal test . Diagonal test How to perform a diagonal test: Place your right hand on the back, right corner and your left hand on the front, left corner of the unit, then attempt to rock the unit from corner to corner. Then, move your right hand to the front, right side and your left hand to the back, left corner and attempt to rock the unit from corner to corner. If the unit is level, it will not rock. However, if the unit is not level, it will rock. If the unit rocks, it will be necessary to adjust the leveling feet of the unit. Adjust the foot under the hand that is on the front of the machine. Higher Tighten Adjustable feet Lower Tighten Lock nut 10mm Adjustable bolt Adjustable feet Lower the foot until there is no gap between floor and foot. And only use adjustment rubber when difference at the leg adjustment is more than Rubber Cup 4620ER3001A (Black) for Tile floors 10mm. 4620ER3001B (Gray) for Wooden floors 3 Step Perform a Rinse and Spin with some clothing in the machine. To do this, put 2~3kg of clothing in the unit, power on the unit, press the Rinse and Spin button, and then start. When the unit reaches the spin cycle, watch for vibrations. If the unit is vibrating, make small adjustments to the leg until they subside. (Try 2Step again) 4 Step Tighten the lock nut against the base of the machine to lock the position leg . Tighen the lock nut 10 9 Test operation 1 Preparation for washing. 2 Press the power button. ·Connect the power plug to the outlet. ·Connect the inlet hose. ·In case of cotton program. 6 5 Check the water heating.
