1. Fan motor in the freezer compartment shall change from standard to high speed rpm in order to increase cooling speed

and load corresponding speed.

2. High speed rpm is only used for the initial power  application and load corresponding  operation. But  standard rpm  is

used  in the  general working conditions.

3. Fan motor in the freezer compartment operates normally when freezer, refrigerator, or home  bar door opens and fan

motor in the freezer compartment operates (the speed changes from high to standard rpm if fan motor operates at high
speed rpm). But fan motor in the freezer compartment stops when refrigerator or home bar door is open and refrigerator
compartment door is closed.

1. Buzzer warns when freezer, refrigerator, or home bar door is kept open for more than 1 minute.

2. Buzzer warns 3 times at 0.5 second interval and then 3 times at 0.5 second on and off in every 30  seconds if door is kept

open for more than 1 minute.

3. Warning is released  when freezer, refrigerator, or home  bar door is closed during door opening alarm.

1. “Bell” sounds when button on the front display is pressed.

3. When forced defrost is selected, warning sounds three times in the following cycle: 0.2 second on and 0.2 second off, 0.2

second on and 0.2 second off, and 0.2 second on and 1.0 second off.

1. Defrost starts whenever the compressor operation time accumulates to seven to seven and a half hours.

2. Defrost starts whenever the compressor operation time accumulates to four to four and a half hours if power is initially

applied (or reapplied after power cut).

3. Defrost completes  when the temperature of defrost  sensor reaches at 5 

°

C. Faulty defrost is indicated if the defrost
