c) If 24 C AT Sensor < 32 C
If 24C AT Sensor < 32C and freezer is set to -17C or colder and cooler is set to 4C or warmer, then fan and compressor
works together.
In other cases, Fan and compressor aren`t working together.
IMPORTANT FUNCTION:
If compressor works in together with fan for 1 hour and cooler compartment still can’t reach damper close value, damper-fan-
compressor will work separately until cooler compartment reaches damper close value. When it reaches to this value, they
return to working together again. (separate working is explained below)
d) If 32 C < AT Sensor < 43 C
Fan and compressor aren`t working together.
e) If AT Sensor > 43 C
Fan and compressor aren`t working together.

4.2. Defrost Control
a) If AT < 13 C
Defrost cycle is fixed to 16 hours (running + stopping)
b) If 18 C < AT < 22 C
If doors aren’t opened during defrost cycle time; defrost cycle is max. 8 hours of compressor running accumulated time or 18
hours of compressor stopping accumulated time.
If doors are opened or previous defrosting is long, defrost cycle time is shortened according to special algorithm.
Minimum defrost cycle time can be 6 hours of compressor running accumulated time
c) If 22 C AT < 30 C
Defrost cycle is fixed to 48 hours (running + stopping)
If doors are opened or previous defrosting is long, defrost cycle time is shortened according to special algorithm.
Minimum defrost cycle time can be 24 hours total time
d) If AT 30 C ;
If door isn’t opened during defrost cycle time; defrost cycle is max. 18 hours of compressor running accumulated time or 28
hours of compressor stopping accumulated time.
Normally defrost function will be completed when defrost sensor reaches to 8C, however if defrost time exceeds 37min, com-
pletion temperature increases to 12C. Compressor will run 5 min. after defrost completion. Fan motor starts 3 min. after com-
pressor. Compressor will run 20 min. continuously after defrost.
4.3. Fan Control
a) If 24 C AT Sensor < 32 C and freezer is set to -17 C or colder and cooler is set to 4 C or warmer
Fan will work together with compressor except below condition :
If stopping time more than one hour and refrigerator temperature warmer than damper on set values ,fan will work untill refriger-
ator temperature reach damper off values.
Important Function:
If compressor works in together with fan for 1 hour and cooler compartment still can't reach damper close value, damper-fan-
compressor will work separately until cooler compartment reaches damper close value. When it reaches to this value, they
return to working together again.
b) For other conditions:
Fan and compressor doesn`t work together except the condition above. While compressor is working, evaporator fan is also
works.
If cooler compartment isn’t cold enough fan continues to work until fridge temperature decreases to [damper close set value].
If both fridge and freezer temperature is at damper close set value, fan stops.
4.3.1. Test Control at the plugging in of the appliance
If FCC sensor > -5C and DFC sensor > -5C;
Set defrost and drain heater ON for 5secs. then set them OFF
Set evap. fan motor ON for 5secs. then set it OFF
Set compressor ON for 5secs. then set it OFF
Other controls can be done via Service Mode

6 Installation Instructions
This section explains how to install your appliance for the most energy-efficient, safe and quiet operation.
Dimensions
W600 x D652 x H1866 (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 unscrew-
ing 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
