SAFETY PRECAUTIONS

Please read the followings  before servicing your appliance. 
 

1.  Check if an electric leakage occurs in the set. 

2.  To prevent electric shock, unplug prior to servicing. 

3.  In case of testing with power on, wear rubber gloves 

to prevent electric shock. 

4.  If you use any appliances, check regular current, 

voltage and capacity. 

5.  Don't touch metal products in cold freezer with wet 

hand. It may cause frostbite. 

6.  Prevent water flowing to electric elements in 

mechanical parts. 

7.  When sloping the set, remove any materials on the 

set, especially thin plate type. (ex.: glass shelf or 
books.) 

8.  When servicing evaporator part, wear cotton gloves 

without fail. It is to prevent wound by sharp fin of 
evaporator. 

9.  Leave a breakage of refrigerating cycle to a heavy 

service center. The gas in cycle inside may soil 
ambient air.
