CFCs have been used in refrigerant as refrigerator and the insulation materials for many years. But it
is now known that these compounds which once seemed so ideal for use as cleaning agents and in
refrigeration systems, destroy the earth’s ozone layer as a result, an international body decided on a
total worldwide ban of harmful CFCs by the end of 1995.

1. SAFETY CAUTIONS FOR REPAIRING
When you repair the refrigerator, please kindly take care for the following cautions.
1.1 Warning
Before repairing unit, unplug supply cord
• Before you repair the refrigerator, please unplug the supply cord.
Use authentic parts when repairing
• When you replace the parts, please use authentic parts to replace defective parts.
Caution during brazing
• When you use touch for brazing, please ensure ventilation.
Otherwise, you will be poisoned by carbon monoxide.
Pay attention to using refrigerant
• If refrigerant touches fire, the gas becomes poisonous gas.
Pay attention to getting electricity shock
• When you check the voltage of terminal, please do not touch the electricity part terminal.
• When you replace the parts, please wait for 3 minutes at least for discharging capacitor.
Check safety after repairing
• Check the screws, parts, lead wires to take in place.
• Check the repairing portion whether circumferential parts are damaged or not.
• Check insulation resistance between supply plug and earth.
• When install refrigerator, check condition of supply cord and plug.
• Wipe off the dust on plug.
• Cutting and seal the electric device carefully.
1.2 Caution
Watch the hot parts
• During operation and after operation, compressor and pipes are hot.
• Also, under these condition, heater are hot.
• Do not burn your fingers when you touch it.
Pay attention to refrigerant
• Do not touch liquid refrigerant. Otherwise your hands may be burnt.
Pay attention to edge of parts
• Otherwise, your fingers may be cut.
Pay attention to fins of evaporator and condenser
• Otherwise, your fingers may be cut.
Before transportation, adjust the bolt
• Otherwise, the floor may be damaged.
Do not touch the pipe after brazing
• Otherwise, your hands may be burnt.
