1. WARNINGS AND PRECAUTIONS FOR SAFETY


   Please observe the following safety precautions in order to use safely and correctly the refrigerator
   and to prevent accident and danger during repair.

   1. Be care of an electric shock. Disconnect power cord from wall outlet and wait for more than
      three minutes before replacing PCB parts.
     Shut off the power whenever replacing and repairing electric components.

   2. When connecting power cord, please wait for more than five minutes after power cord was
      disconnected from the wall outlet.

   3. Please check if the power plug is pressed down by the refrigerator against the wall.
      If the power plug was damaged, it may cause fire or electric shock.

   4. If the wall outlet is over loaded, it may cause fire.
     Please use its own individual electrical outlet for the refrigerator.

   5. Please make sure the outlet is properly earthed, particularly in wet or damp area.

   6. Use standard electrical components when replacing them.

   7. Make sure the hook is correctly engaged.
     Remove dust and foreign materials from the housing and connecting parts.

   8. Do not fray, damage, machine, heavily bend, pull out or twist the power cord.

   9. Please check the evidence of moisture intrusion in the electrical components.
     Replace the parts or mask it with insulation tapes if moisture intrusion was confirmed.

   10. Do not touch the icemaker with hands or tools to confirm the operation of geared motor.

   11. Do not let the customers repair, disassemble and reconstruct the refrigerator for themselves.
     It may cause accident, electric shock, or fire.

   12. Do not store flammable materials such as ether, benzene, alcohol, chemicals, gas, or
       medicine in the refrigerator.

   13. Do not put flower vase, cup, cosmetics, chemicals, etc., or container with full of water
       on the top of the refrigerator.

   14. Do not put glass bottles with full of water into the freezer.
