There are special components used in this equipment which are important for safety. These parts are marked by
in the Schematic Diagrams, Circuit Board Diagrams, Exploded Views and Replacement Parts List. It is essential that
these critical parts should be replaced with manufacturer’s specified parts to prevent shock, fire or other hazards. Do
not modify the original design without permission of manufacturer.
IMPORTANT SAFETY NOTICE
WARNING
The service information is designed for experienced repair technicians only and is not designed for use by the general
public. It does not contain warnings or cautions to advise non-technical individuals of potential dangers in attempting
to service a product. Products powered by electricity should be serviced or repaired only by experienced professional
technicians. Any attempt to service or repair the product or products dealt within this service information by anyone
else could result in serious injury or death.
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 transportatin, adjust the bolt
• Otherwise, the floor may be damaged.
Do not touch the pipe after brazing
• Otherwise, your hands may be burnt.

Contents of discussion
Illuminance sensor will be added. Therefore, an inspection of whether to be able to operate normally is necessary.
< In-process inspection of illuminance sensor >
①ECONAVI LED blinks at the start of in-process inspection check whether ECONAVI LED blinks.
④As long as the illuminance sensor is normal, ECONAVI LED goes out check whether ECONAVI LED goes out.
③Lighting of illuminance sensor shall be varied manually or automatically after the completion of aging. (If there is
input variation corresponding to a dark area and a bright area, microcomputer judges that as normal)
In Japan, a dark area and a bright area have been created in the place for inspection process.
②ECONAVI LED lights up after 1 min., of the start of in-process inspection (because if there is less input variation,
microcomputer judge that as abnormal) check whether ECONAVI LED lights up.
During IN-PROCESS INSPECTION
