SAFETY AND PRECAUTIONS
1) For starters, be sure to check any chances of the leakage of electricity.
2) You could handle a part in the vicinity of electricity after unplugging.
3) You should put on rubber gloves to prevent an electric shock on operation test.
4) Make sure the rated current, voltage, capacity before using an instrument.
5) Keep your wet hands away from the metal goods in the freezer compartment not to be frostbitten.
6) Be careful not to let water to permeate the electric part in the machine room.
7) With the door open during your repair, you might be hurt by that door.
8) You should give a tilt to the refrigerator for your safe after removing the breakable goods inside the refrigerator.
9) You'd better use gloves if you fix it up around the evaporator.

1) Total Run-time of COMP : 6, 8, 10, 12, 14 hours
2) Running-rate of COMP (each 2hours running-rate) : more than 80%
3) Total time of Door openings : 10minutes
4) Total Time (COMP-On + COMP-Off) : 60hours
5) Ambient Temperature : more than 35
6) In each Error : R1, F1, D1, F3, RT-S, Door-SW Error
2. Terms to start Defrosting Period
1) The Defrosting starts with the following conditions, in case total
COMP-run time passes 6, 8, 10 or 12hours
¨ çwhen an Error occurs
¨ èwhen running-rate of COMP is more than 80%
¨ éwhen total Door-opening time is more than 10minutes
¨ êwhen the ambient temperature is more than 35
2) Defrosting starts unconditionally when total COMP-run time passes
14 hours, under the condition that terms of 1) are not satisfied.
3) Defrosting starts immediately when Total-time (COMP-On + Off time)
is more than 60 hours, under the condition that terms of 1) and/or 2)
