precautions in order to conduct the maintenance procedures in a safety fashion.

1-1.

Caution when you replacing compressor.

• Do not smoke. Remove all the possible ignition sources and then replace compressor in wellaired places.

• Don’t use welding machines if R600a refrigerant does not exposed.

• In the case of gas leakage, always open the windows.

• When cutting the SUCTION, DISCHARGE pipe of the compressor, always take caution of the inner pressure of the remaining gas.

1-2. Take out the power plug

• Always take out the power plug from the outlet when doing repairs.

1-3. Be careful of electric shocks

• When inspecting the circuit, don’t touch the battery charger and be careful of electric shocks.

1-4. Use proper components

• Always use the component labeled in the service component chart when replacing components for repairs.

1-5. Use proper tools

• Always use proper tools for repairs. If worn out tools are used, it would cause defects in tuning and electrical contact, leading to accidents.

1-6.

When doing repairs, inspect the POWER CORD or whether there is fire in the lead wire

and make sure they are replaced.

1-7. Cutting of LEAD-WIRE

• For connecting the lead-wire that has been cut off, use soldering or connector and always disconnect the vinyl tapes.

1-8. Check for disconnection

• After completing the assembly, always measure the disconnection resistance level, and turn on the power after checking it is above 1MΩ.

1-9. Earth

• Check the status of earthing and repair the incomplete ones.

1-10. Be careful of children

• There is always the possibility of danger when doing repairs so make sure that children can’t come nearby.

Cleaning : After completing repairs, clean

the surrounding area and the refrigerator and tell the consumer about the repairs being made.

This appliance contains a small amount of the refrigerant isobutane(R600a), a natural gas with high

environmental compatibility but which is also combustible. When transporting and installing

the appliance, care should be taken to ensure that no parts of the refrigerating circuit are damaged. Refrigerant squirting out of the pipes could ignite or cause an eye injury. If damage occurs nevertheless, avoid any flames or potential sources of ignition, and air the room in which the appliance is standing for several minutes.

• In order to avoid the creation of a flammable gas-air

mixture if a leak in the refrigerating circuit occurs, the size of the room in which the appliance may be sited depends upon the amount of refrigerant used. The room must be 1m

in size for every 8 g of refrigerant R600a inside the appliance. The amount of refrigerant contained in your particular appliance is shown on the identification plate inside the appliance.

• Never start up an appliance showing any signs damage. If in doubt, consult your dealer.
