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 PWB 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
