2) When the power is engaged for the first time, the defrost cycle for the freezer and the refrigerator will
begin after 4 hours of the accumulated compressor on-time.
3) A defrost interval depends on the ambient temperature, the number of door openings, and the door open
time.
4) The defrost cycle is composed of a pre-cool process (F-Fan and COMP) for 30 minutes, a heating
process, and a resting for 8-12 minutes to drain.
5) A minimum interval is 6 hours and a maximum is 11 hours for the refrigerator, and 12 hours and 22 hours
for the freezer, respectively.
6) When the system runs only for the refrigerator (R-Fan and COMP) and if the refrigerator can not reach the
set temperature within 2 hours, an R-defrost process will begin.
7) After the 6) process, when the compressor on-time reaches 4 hours, R-,F-defrost will begin
simultaneously.
8) If a defrost cycle ocurs during Power Freeze operation, the defrost cycle will begin after the completion of
Power Freeze operation.
