5 2.FEATURES & TECHNICAL EXPLANATION 2-1. FEATURES Direct Drive System The advanced Brushless DC motor directly drives the drum without belt and pulley. Built-in Heater Internal heater automatically heats the water to the best temperature on selected cycles. Child Lock The Child lock prevents children from pressing any Buttons to change the settings during operation. More economical by Intelligent Wash System Intelligent Wash 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. Low noise speed control system By sensing the amount of load and balance, it evenly distributes load to minimize the spinning noise level. Inverter Direct Drive system The advance Brushless DC motor directly drives the drum without belt and pulley. 6 motion Washer is able to perform various drum actions or a combination of different actions depending on the wash program selected. Combined with a controlled spin speed and the ability of the drum to rotate both left and right, the wash performance of the machine is greatly improved, givong you perfect results every time.

4 To reduce the risk of personal injury, adhere to all industry recommended safety procedures including the use of long sleeved gloves and safety glasses. Failure to follow all of the safety warnings in this manual could result in property damage, personal injury or death.

WATER LEVEL CONTROL This model adopts a pressure sensor which can sense the water level in the tub. Water supply is stopped when the water level reach the preset level, then washing program proceeds. Spinning does not proceed until the water in the tub reduces to a certain level. water temperature washing time rinse time the best washing performance spin rhythm, time laundry amount FUZZY LOGIC selected washing temperature SENSING EFFECT PROCESSING DETERMINATION 2-4.

8 4.INSTALLATION INSTALLATION The appliance should be installed as follows. Check the conditions of installation area. 1. Check level ground. 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 for humidity or any foreign objects under the feet. Clean the floor, there should be no 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. 1 Open the box and check appliance condition. 2 horizontal Carpet Paper Laminated paper Purchased stopper Base Packing Washer Spanner This leveling (or spanner) wrench must be used to remove the transit bolts and level the unit. This should be kept for future use.

9 1. Unscrew the adapter ring plate and the 4 adapter retaining screws. 2. Push the adapter onto the end of the tap so that the rubber seal forms a watertight connection. Tighten the adapter ring plate and the 4 screws. 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. • Water supply pressure must be between 100 kPa and 1000 kPa (1.0 ~ 10.0 kgf / cm 2 ) • Do not strip or crossthread when connecting Inlet hose to the valve. • If the water supply pressure is more than 1000 kPa, a decompression device should be installed. • Periodically check the condition of the hose and replace the hose if necessary. Type-A : Connecting Screw-type hose to tap with thread • Screw the hose connector onto water supply tap. ■ Connecting water supply hose Step1 : Check rubber seal inlet hose Step2 : Connect hose to water tap • Two rubber seals are supplied with the water inlet hoses. They are used for preventing water leaks. Make sure the connection to taps are sufficiently tight. Upper connector Rubber packing Plate Water supply hose Fixing screw Hose connector Rubber seal Type-B : Connecting Screw-type hose to tap without thread

10 Please use the horizontal tap Horizontal tap Extension tap Square tap 1. Unscrew the adapter ring plate and the 4 adapter retaining screws. 2. Remove the guide plate if the tap is too large to fit the adapter. 3. Push the adapter onto the end of the tap so that the rubber seal forms a watertight connection. Tighten the adapter ring plate and the 4 screws. 4. Pull the connector latch plate down, push the inlet hose onto the adapter, and release the connector latch plate. Make sure the adapter locks into place. Ring plate Guide plate Latch plate Type-C : Connecting one touch type hose to tap without thread Step3: Connect hose to washer • Make sure that there are no kinks in the hose and that they are not crushed. When your washer has two valves. • The Inlet hose With the red connector is for the hot water tap. • If the washer has two valves, energy is saved by using the hot valve. NOTE After connecting inlet hose to water tap, turn on the water taps to flush out foreign substances (dirt, sand or sawdust) in the water lines. Let water drain into a bucket, and check the water temperature. NOTE After completing connection, if water leaks from the hose, repeat the same steps. Use the most conventional type of faucet for water supply. In case the faucet is square or too big, remove the spacing ring before inserting the faucet into the adaptor.

11 Connect Drain Hose. 6 Connect power plug. 7 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. 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. Connect the power plug to the wall outlet. Avoid connecting several electric devices, it may be the cause of a fire. about 100 cm about 145 cm Laundry tub Retainer Tie strap Hose max. 100 cm Max. 100cm about 105 cm Max. 100cm
