Chapter 1 General Information 
1-1. General Guidelines 
When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been 
overheated or damaged by the short circuit. After servicing, see to it that all the protective devices such as 
insulation  barriers,  insulation  papers  shields  are  properly  installed.  After  servicing,  make  the  following 
leakage current checks to prevent the customer from being exposed to shock hazards. 
1) Leakage Current Cold Check 
2) Leakage Current Hot Check 
3) Prevention of Electro Static Discharge (ESD) to Electrostatic Sensitive 
1-2. Insurance test 
1.  Check if there is any leak of current. 
2.  Cut out the power supply before the repair to avoid an electrical shock hazard. 
3.  In the case of a live-line test, insulating gloves should be worn to avoid potential electrical shock. 
4.  Confirm the rated current, voltage and capacity before testing with any kinds of instruments. 
5.  Watch if the upper door is open when you check something at a lower position. 
6.  Take out every part in the cabinet before moving the machine, especially things like panels (e.g. glass 
shelf). 
7.  Please wear intact cotton gloves when repair any parts of the evaporator, so that scratches by the sharp 
fins can be avoided. 
8.  If there is a breakdown with the refrigeration system, please surrender the machine to the service center, 
else the leaked refrigerant may pollute the atmosphere. 
9.  The refrigerator use AC of 220V with a frequency of 50Hz. 
10. A big fluctuation of voltage (exceed the range 187~242V) may cause a start failure of the refrigerator, a 
burn-out of the control panel and compressor, or an abnormal sound from the compressor in operation. In 
this condition an automatic voltage regulator over 60W should be added. 
11. Take  care  not  to  damage  the  supply  line.  Don’t  yank  at  the  line;  pull  the  plug  out  gently  from  the 
receptacle. Don’t press the line under the cabinet or step on it. Take care not to roll on or damage the 
supply line when moves the machine from the wall.   
12. In the case of leakage of inflammable gases like carbon monoxide, open the door and windows. Don’t 
pull out or insert the plugs of the appliance. 
13. Don’t touch the refrigeration surface of the freezing compartment when the refrigerator is in operation, 
especially when your hand is wet, else you may be glued to the surface. 
14. Pull out the plug of power supply during clearance or power outage. Wait at least five minutes to resume 
the power supply in order to prevent damage to the compressor caused by continuous restart.
