Refrigerating room

This model is multi-flow type
which flows out cold air from
each shelf space. The hot air
after making the refrigerator
cold, flows into cooling system
through the front upper part.

Do not put food having much
moisture at the middle part of
each shelf space ("A", "B" and
"C" part). It can be frozen owing
to the low temperature.

11. ELECTRONIC FUNCTION

1. FR-440P

1) How to use the panel

Freezer Section Temp. Indicator LED

It checks the temp. In freezer section. If the Temp. Is
more than -5ûC, the warm temperature LED is
turned on, and if it is less than -5ûC, the normal
temperature LED is turned on.

Normal Temp. LED

Warm Temp. LED

Quick freezing SW

Quick Freezing

Pressing the quick freezing switch turns on LED and
performs quick freezing (COMP is operating for 90
min continuously.)
Pressing the switch again turns off LED and stops
Quick freezing.

Quick feezing LED

Temperature Control dial

It is used for changing the temperature in freezer
compartment.
Temperature control range:

ON OFF

Low -11ûC -17ûC
High -21ûC -27ûC

Contents Remark

1. If press the quick freezing switch, then illuminates quick
freezing LED and starts quick freezing. (If press again, then
stops quick freezing)

2. COMP. and Fan operate for 90 min continuously.

3. After 90 min. F-sensor checks the temperature. If it is COMP.
on temperature, it continues quick freezing until it reaches
COMP off temperature.

4. If it becomes auto defrosting time during quick freezing,
defrosting starts from Pre-cool after finishing quick freezing.

5. If quick freezing switch is turn on during defrosting Pre-cool,
defrosting starts from Pre-cool after finishing quick freezing.
But if COMP. has been operating for more than 40 min., the
Pre-cool will be omitted.

6. If quick freezing switch is turned on during Defrosting Heater
on or Fan delay, it performs quick freezing just after finishing
defrosting. But the quick freezing LED comes on immediately.

1. COMP. on/off temperature is controlled by F-sensor.

2. Usually COMP. and the fan operates simultaneously.

1. Restarting in 6 min. after COMP. off.

1. If F-sensor detects temperature over -5ûC, warm temperature
LED is on.

2. During defrosting, the normal temperature LED is always on
and F-sensor detects the temperature after finishing defrosting.

3. In quick freezing, warm temperature LED and normal
temperature LED are off.

Contents Remark

1.After accumulated 13 hours of COMP. operation, it enters to

defrosting mode.

2.When power is loaded for the first time or when instant power

failure occurs, D-sensor detects temperature below 3.5˚C. It
immediately enters into defrosting mode.

3.During Pre-cool period, it operates COMP. and fan for 40 min.

regardless of F-sensor.

4.After finishing Pre-cool, the D-heater is immediately turned on.

5.At D-sensor temperature 13˚C, the D-heater stops.

6.If the D-heater does not stop within 1.5 hours, it enforcedly

turns off D-heater.

7.Fan, COMP. operates in 5 min. unconditionally after finishing

defrosting.

8.The defrosting LED is always on from Pre-cool to fan & COMP.

1.It is set by forced defrosting switch.

2.It can not be set when D-sensor temperature is above 3.5˚C.

3.Manual reset is not possible.

4.If the D-sensor detect 13˚C the D-heater stops.
