Warnings about Temperature Adjustments
• Your temperature adjustments will not be deleted when an energy breakdown occurs.
• It is not recommended that you operate your fridge in environments colder than 10°C in terms of
its efficiency.
• Temperature adjustments should be made according to the frequency of door openings and the
quantity of food kept inside the fridge.
• Do not pass to another adjustment before completing an adjustment.
• Your fridge should be operated up to 24 hours according to the ambient temperature without
interruption after being plugged in to be completely cooled. Do not open doors of your fridge
frequently and do not place much food inside it in this period.
• A 5 minute delaying function is applied to prevent damage to the compressor of your fridge, when
you take the plug off and then plug it on again to operate it or when an energy breakdown occurs.
Your fridge will start to operate normally after 5 minutes.
• Your fridge is designed to operate in the ambient temperature intervals stated in the standards,
according to the climate class stated in the information label. We do not recommend operating your
fridge out of stated temperatures value limits in terms of cooling effectiveness.
Note: If the temperature of the environment is higher than 38°C, the freezer partition temperature
cannot be adjusted to -22°C and -24°C. It can only be adjusted to the values of -16°C, -18°C, -20°C.

The freezer fan motor and the condenser fan motor work parallel time with the
compressor. The freezer fan motor works when the freezer compartment door is
opened. It is normal.
The cooler fan motor works parallel time with the compressor. However it could work
while the compressor is stopped or the cooler is defrosting.

Freezer Defrost Program
•According to the conditions of usage, the defrost might be activated after the min
compressor running time; 8 hours or max total time; 55 hours. Below matters are also
effected;
•Consisted ice amount,
•Door open-close,
•Sudden usage variance,
•Cooler sudden temperature rise,
When the refrigerator works on first time;
If the cooler compartment defrost sensor and the freezer compartment defrost sensor are
hotter than -5°C, the test system works automatically. These below components are tested
automatically every 5 seconds.
If the appliance does not start the automatic control process, please wait 10 minutes. After
that, if it starts there are two options either open sensor or short circuit situation.
The compressor starts and stops after 5 seconds.
The defrost resistance stars and stops after 5 seconds.
The cooler defrost resistance starts and stops after 5 seconds.
The DC Radial Fan starts and stops after 5 seconds.
After these steps, the system waits 5 minutes and then it will switch normal mod.
There are three types of sensors. They are cooler, freezer defrost, cooler defrost sensors. Cooler and
freezer defrost sensors have the same features but their cable length is different. The resistance
values of all sensors decrease when the temperature values of the sensors increase. For example,
the resistance value that is 33 kΩ in the -35.5 ºC goes down to 1kΩ in the 45 ºC and therefore the
ambient temperature should be considered while the sensor is being checked. If the ambient
temperature is 25 ºC, the measuring device shows about 2.2kΩ (if ntc sensor is steady).
NTC Sensor
Cooler Defrost Program
The cooler defrost and the freezer defrost are operated parallel except those below.
If the cooler defrost sensor does not feel 5°C three times during a particular period of time.
•Defrost will be activated after the refrigerator works max 9 hours. According to the
conditions of usage, the defrost might be activated (due to mentioned those below) after
the compressor works min 5 hours.
•Consisted ice amount,
•Door open-close,
•Sudden usage variance,
•Cooler sudden temperature rise,

Special Programs
In Case of Power Cut
•All regulated parameters and functions are kept in memory when the power cut.
• When the electricity comes, if the defrost sensor temperature is lower than -5 ºC the
compressor works 5 minutes later. If it is higher than -5 ºC.
Other Features
Warnings : The door open warning is active 2 minutes later and it alarms.
Door Direction : It is possible to reverse the door.
Gasket : It is possible to change the gasket.
Freezer Defrosting Time
The Defrost is disabled when the defrost sensor temperature feels 8ºC.If defrost time
passes 37 minutes, defrost completing temperature will be rise to 15ºC.
The cooler defrost and the freezer defrost are operated parallel except those below. The
cooler defrost will not work if the freezer defrost stops.
The defrost process stops when the defrost sensor temperature feels 7ºC. At the low
ambient temperature or when the compressor stops; to balance, defrost stops when the
defrost sensor temperature feels 15⁰C. But if the defrost time or the compressor stopping
time goes over 6 hours, the resistance will be stopped.
Compressor delay: First, the defrost process ends, the system waits 5 minutes, just after that
the compressor is active.
