MICOM FUNCTION
2-5. ICE PLUS freezing
1. ICE PLUS freezing is a function to increase the cooling speed of the freezer compartment by running both the
compressor and the fan simultaneously.
2. ICE PLUS is cancelled and the refrigerator returns to its default setting in the event of a power interruption.
3. Selecting ICE PLUS changes only the speed of the cooling without affecting the set temperature.
4. The temperature can be adjusted even when ICE PLUS has been selected and is in progress.
5. The freezer operates at whatever temperature was set at the time ICE PLUS was selected.
6. If you select ICE PLUS, the compressor and fan will run until it is deselected or the cycle time has elapsed.
(3 hours : compressor and fan run / 3 ~ 24 hours : COLDEST operation)
7. If a defrost cycle occurs while an ICE PLUS is already running, ICE PLUS runs for its remaining cycle time after the
defrost cycle is completed. If the defrost cycle takes longer than 30 minutes, ICE PLUS will run for only 2 hours at the end
of the defrost cycle.
8. If you press ICE PLUS during a defrost cycle, the ICE PLUS indicator will illuminate but the compressor will not operate
until the defrost cycle is complete.
9. If you press ICE PLUS within 7 minutes of compressor cut-off, the compressor will not operate until the 7-minute delay
has passed.
10. The freezer fan motor runs at high speed during the ICE PLUS cycle.
2-6. OptiFresh Function
1. The OptiFresh bin is positioned at the bottom of the refrigerator compartment and has a separate temperature control to
allow perfect storage of fruits and vegetables.
2. OptiFresh comprises of OptiFresh sensor at the rear of OptiFresh and a damper between OptiFresh and Freezer
compartment and a temperature adjusting display at the top of it.
3. When powered on, the initial NOTCH of OptiFresh display will be on OptiFresh Crisper.
If only the refrigerator door is opened, the OptiFresh LED will be ON.
4. The OptiFresh sensor opens and closes the damper based on the temperature.
5. The OptiFresh damper will cycle every hour to prevent icing up.
