4 Technical Descriptions
4.1. Setting the temperature
4.1.1. Fridge compartment (PC)
At the time of purchase, the temperature is set to 4°C
4.1.2. Freezer compartment (FC)
At the time of purchase, the temperature is set to -18°C
4.1.3. Chill compartment
You can adjust the temperature of the chill compartment by opening and closing the sliding part which is located inside the compart-
ment.
1. Press (upper) once and then press it again within 1 second.
• The temperature can be set.
2. Press the button repeatedly until the desired temperature is set.
• If no operation is performed for 1 second during the setting process, the set value will
flash and a beep will be heard indicating that the temperature is now set.
Note:
• When Super Cool Mode, Super Freeze Mode, Eco Mode, or Holiday Mode ends or is can-
celled, the unit returns to its previous settings.
1. Press (lower) once and then press it again within 1 second.
• The temperature can be set.
2. Press the button repeatedly until the desired temperature is set.
• If no operation is performed for 1 second during the setting process, the set value will
flash and a beep will be heard indicating that the temperature is now set.
Note:
• When Super Cool Mode, Super Freeze Mode, Eco Mode, or Holiday Mode ends or is can-
celled, the unit returns to its previous settings.
Open
Turn the sliding part to the opening position to set the compartment temperature lower by
1 °C to 2 °C than that set for the PC, and make the compartment work as the chill compart-
ment.
Closed
Turn the sliding part to the closing position to set the compartment temperature same as
that set for the PC, and make the compartment work as a part of the fridge compartment.
• When this compartment is used as 0 °C compartment, keeping food in the chill compartment
instead of the FC or PC allows food retain freshness and flavour longer, while preserving its
fresh appearance, When chill compartment drawer becomes dirty, remove it and wash it with
water. (Water freezes at 0 °C, but foods containing salt or sugar freeze at temperature lower
than that) Normally people use the chill compartment for raw fish, lightly pickled and rice,
etc...
• Pull the chill compartment drawer out toward you. the cover will open automatically.
Note:
• Do not put foods you want to freeze or ice trays in order to make ice.

4.2. Defrost Control
4.2.1. Calculating defrost starting time
According to this;
a) If ATC < 23 °C
Fix the defrost cycle to 16 hours (running + stopping)
b) If 23 °C < ATC < 28 °C
If door is not opened;
First Defrost cycle time will be fixed to 16 hours.
Second defrost cycle time will be fixed to 20 hours.
For next defrosts:
If doors isn’t opened during defrost cycle time;
fix the defrost cycle to 30 hours (running + stopping)
c) If 28 °C > ATC ≥35 °C
If doors isn’t opened during defrost cycle time;
defrost cycle is max. 8 hours of compressor running accumulated time (max at non door opens & close operation) or 16 hours of
total time (runnig+stopping)
d) ATC ≥35 °C ;
If doors isn’t opened during defrost cycle time;
defrost cycle is max. 12 hours of compressor running accumulated time or 16 hours of total time (running+stopping)
Checking of ambient temperature will be done every 10 min
Defrost conditions (durations) can be changed according to new ATC.
Step 1. When defrost accumulated time reach to appointed time;
Check if FCC sensor temp. < compressor OFF temp,
If YES, go to step 2 (1)
If NO and compressor running accumulated time is longer than 45min. go to step2. (2)
If NO and compressor running accumulated time is not longer than 45min. return to step1 (3)
Step 2. Set compressor OFF and evaporator fan motor ON. Wait 3 min. and start defrosting.

11
4.3. Fan Control
While compressor is running, evaporator fan is running.
When compressor stops and if damper motor is closed 2min run - 2 min stop operation starts and continue until compressor runs
or damper motor opens again.
If ambient temperature is ATC ≤22 °C or ATC ≥30 °C
• While compressor is running, evaporator fan motor is running.
• If PCC sensor is warmer than damper on set values damper must be on and fan motor must work continiously untill PCC sensor
reach to damper close set values.
• If PCC sensor is colder than damper close set values damper must be off and if compressor is stopping fan also must be off.

6 Installation Instructions
This section explains how to install your appliance for the most energy-efficient, safe and quiet operation.
Dimensions
NR-B29SG2/NR-B29SW2: W600 x D652 x H1898 (mm)
NR-B32SG2/NR-B32SW2: W600 x D652 x H2044 (mm)
Unpacking your appliance
Remove all packaging and tape.
Choosing the right location
Ventilation
As the appliance gives off heat during operation, it should be
installed in a well-ventilated, dry room with plenty of space above
and behind it, as shown in Figure 1.
If you can hear it vibrating, it needs more space.
Temperature
The room temperature affects the refrigerator’s energyefficiency,
i.e. how much electricity it uses to chill and freeze foods.
For the best results, install your refrigerator:
• away from direct sunlight
• away from radiators, cookers or other heat sources
• where the room temperature corresponds to the climate classifica-
tion for which the appliance is designed. Refer to the Specifications
Section for your appliance’s climate classification.
Level
Install on a level floor that’s strong enough to support a fully loaded
refrigerator.
You can adjust the level of the refrigerator by screwing or
unscrewing the two adjustable front legs as shown in Figure 2.
This prevents vibration and noise.
If the appliance is to stand on a carpeted or vinyl floor, put a solid
board underneath it first. This will protect your floor against possible
color change due to heat given off by the appliance.
Refrigerator door
The refrigerator’s door hinges can be swapped over, from the right side to the left, so that the doors open in the
opposite direction. If this is more convenient in your home, please contact our service centre listed on the attached
sheet or access to our Web site (http://panasonic.net).
We could not be held responsible if you replace the hinges by yourself.
Parts for switching door opening direction are included in the unit packaging.

15
Installing the distance guides
To prevent the condenser (the black backside component with fins)
from touching the wall, put on two plastic distance guides in its
place rotating 90°.
Cleaning
After installation, wipe the appliance clean with warm water.
Connecting the mains plug to the household mains socket
You can connect the mains plug immediately after installation.
After the appliance is plugged, all symbols will appear for a moment, and then the startup values will appear as -18 °C on freezer setting indi-
cator and 4 °C on fridge setting indicator.
All buttons on the control panel are touch-operated. (Only press to activate the button you want to operate.)
Notes:
• Cooling may take longer in the summer months or at other times when the room temperature is higher.
• If you need to unplug the refrigerator, wait at least 10 minutes before you plug it back in again. If not, you might damage the compressor.
Ambient room temperature
You'll find your refrigerator's climate classification on the rating plate in the left side of the fridge compartment. It shows the room temperature
the appliance is designed to work in.
Climate classification Permitted ambient temperature
SN (Extended Temperate) +10 °C to 32 °C
N(Temperate) +16 °C to 32 °C
ST (Subtropical) +16 °C to 38 °C
T(Tropical) +16 °C to 43 °C
