3 1 Precaution When performing troubleshooting and part replacement during servicing, note the following safety precautions: 1.1 Safety Precautions Use Genuine Parts The components of the washing machine have safety features such as non-combustibility and voltage withstanding. Therefore, always use the same part as suggested by the maker. In particular, be sure to use only designated parts in case of major safety parts identified by the marker Grounding Connect the grounding wire to the shell plate, and bury it under at least 25cm of earth : alternatively, connect the ground wire to the appropriate pin on a properly grounded power receptacle. ever connect the wire to a telephone line, lightning rod, or gas pipe. 3

4 1 Precaution 1.2 Servicing Precautions Observe Warnings Be sure to follow special warning and precautions that are described on part labels and in the owner's manual Parts Assembly and Wiring Be sure to use insulation material (such as tube and tape). And be sure to restore all parts and wires to their original position. Take special care to avoid contact with sharp edges Perform Safety Checks after Servicing After servicing, check to see that the screws, parts, and wiring are restored to their original positions, and check the insulation between the external metals and the socket plug. In addition, place the washing machine in a level position (less than 1(one) degree) to prevent vibration and noise during operations Insulation Checks Pull out the plug from the power receptacle, pour water into the spin tub, and then set the timer. Check to see that the resistance insulation between the terminals of the plug and the externally exposed metal is greater than 1M. ote :When it is impossible to perform insulation check with a 500V insulation resistance tester, use other testers for inspection. 4

5 1.3 CAUTIOS FOR SAFET Please observe the following notes for safety. The symbols indicate as follows. Symbol Meaning WARIG CAUTIO Indicates possibility of death or serious injury of a repair technician and a person nearby through the misconducted work, or of a user by a defect of the product after the work performed by the technician. Indicates possibility of injury or physical damages* of a repair technician and a person nearby through the misconducted work, or of a user by a defect of the product after the work performed by the technician. Graphic Symbol Meaning ELECTRIC SHOCK indicates a caution (including a warning). Specific instruction is followed by a graphic or characters in or near Symbol left warns an electric shock. DO OT DISASSEMBLE indicates prohibition (act must not be conducted). Specific instruction is followed by a graphic or characters in or near. Symbol left warns not to disassemble. UPLUG POWER indicates forcing (act must be conducted). Specific instruction is followed by a graphic or characters in or near. Symbol left warns to unplug the power cord. 5

6 1.3 CAUTIOS FOR SAFET Please observe the following notes for safety. The symbols indicate as follows. WARIG OUT OF CHILD Advise the customer to keep children out of the work place. Children may be injured with a tool or a disassembled part. UPLUG POWER USE REPAIR PARTS CHECK ISULATIO RESISTACE Unplug power cord for the work such as disassembling which is not unnecessary to power on. Do not hold the plug by a wet hand. Failing to unplug may cause an electric shock. Use the specified repair parts when repairing the product. Otherwise, a malfunction or a defect may occur. Also, a short circuit, ignition or other danger to the customer may occur. After repair, measure insulation resistance between the charging part (power cord plug) and the non-charging metallic part (ground) with an insulation resistance meter (500V). The resistance shall be 10M or more. Failing to check the insulation resistance may cause a short circuit, electric shock or other diseases to the customer. DO OT MODIF Do not modify the product. An electric shock or ignition may occur. DO OT DISASSEMBLE AD REPAIR Only a repair technician can disassemble and repair. An electric shock, ignition or malfunction may cause injury. 6

7 WARIG USE EXCLUSIVE SOCKET COECT GROUDIG WIRE Use an exclusive A socket for the washing machine. Otherwise, an electric shock or ignition may cause. Sharing the same socket with other instrument causes heating of a branch socket and result in a fire. Unplug power cord for the work such as disassembling which is not unnecessary to power on. Do not hold the plug by a wet hand. Failing to unplug may cause an electric shock. COECT GROUDIG WIRE Connect the grounding wire. Failing to do so may cause an electric shock when a short circuit occurs. Consult an electric work shop or a sales shop. DO OT USE WET PLACE Do not install in a bath room or a place exposed to wind or rain. An electric shock or a short circuit may cause a fire. DO OT SPLASH WATER Do not pour or immerse electrical parts into water or liquid solution. An electric shock or ignition may occur. REMOVE DUST Wipe off dust adhered to the plug of power cord. Dust may cause a fire. 7

8 WARIG AVOID IFLAMMABLE COECT GROUDIG WIRE ISTALL CAREFULL Do not put inflammable into the washing tub. Do not put cloths stained with kerosene, gasoline, benzene, thinner, alcohol, etc. lt may cause a fire or explosion. Do not touch the laundry before the spin basket stops completely. The laundry entangles your hand causing an injury even if the basket rotates slowly. Pay special attention to children. CAUTIO Ask an electric work shop to install the product. Install the product securely and safely according to the electrical equipment technical standard and the wiring standard. Incorrect work causes an electric shock and a fire. DO OT PULL DAGER HAD WATER LEAKAGE Do not pull the power cord when unplugging. Hold the power plug to unplug. An electric shock or short circuit may cause a fire. Do not insert your hand under the washing machine during operation. There is a rotary part under the machine which may cause an injury. Before starting washing, open the faucet and check water supply hose joint which shall not be loosened for no water leaks. The loose screw or hose joint may cause water leakage resulting in an unexpected damage. 8

9 2 Factory Pattern Detection When the repairing work is done, select the "Time" programme to operate the dryer for at least 10 minutes. During this time, check if the dryer the tumble turnning right and there is no undesired noise. After the programme is done, open the door, use your hand to check the tumble. If the tumble is warm, that means the dryer operates well. 9
