CONTENTS

1. PRECAUTION

When performing troubleshooting and part replacement during servicing, note the

following safety precautions:

1-1. Safety Precautions

1-1-1. 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.

1-1-2. 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. Never connect the wire to a telephone line, lightning rod, or gas pipe.

1-2. Servicing Precautions

1-2-1. Observe Warnings

Be sure to follow special warning and precautions that are described on part labels and in

the owner's manual.

1-2-2. 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.

1-2-3. 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.

1-2-4. 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• .

Note :When it is impossible to perform insulation check with a 500V insulation

resistance tester, use other testers for inspection.

3-2-3. Grounding

1) Upon installing grounding,make sure if power socket is out

of power outlet.

2) Grounding should be connected to eithermetal water

supply

pipe or copper grounding pole deeper than 25cm in the damp

ground. (Fig 1)

3) If water pipe is a plastic, no protection is obtained from

a possible electric shock.

4) If the power outlet is available with grounding connection,

grounding in the washingmachine should be firmly connected

the connection of the outlet. (Fig 2)

5) You should not connect, the grounding to the gas-pipe

because

it will cause an explosion. (Fig 3)

6) If the grounding is connected to either telecommunication

line

or lightning-arrest line, an extreme hazard is caused therefore,

no connection should bemade to such lines. (Fig 4)
