CAUTIONS AND INFORMATIONS
In case of following troubles, the cause is not related with the failure of refrigerator.
Please mention the correct way to the customer for the use of refrigerator when the repairing.
1. Some foods freezed in the refrigerator compartment.
Do not place food directly in front of
cold air outlet.
This may lead to the food freezing.
cold air flow
IN
OUT
2. Some plastic parts were cracked or splitted.
Some household cleaning chemicals may affect the internal
food liner and plastic parts resulting in splitting or cracks
occurring.
When cleaning all plastic parts inside this refrigerator, only
use diluted dishwashing liquid(soapy water). Make sure that
all plastic parts are thoroughly rinsed with water after cleaning.
3. IT IS NORMAL for the refrigerator to produce the following sounds.
Cracking or crunching sound;
Sound produced by expansion and contraction of inner walls and internal parts during cooling.
Squeaking sound;
Sound produced by expansion and contraction of internal parts.
Sound of flowing fluid (gurgling sound, fizzing sound);
Sound of refrigerant flowing in pipes (sound may become louder from time to time).

1. ADJUSTABLE TEMPERATURE CONTROL
(1) Temperature control of freezer
Thermostat (senses freezer temperature) operates on ON/OFF switchover to control the compressor and
cool air circulating fan (F-fan motor) , and allows the freezer temperature to keep at a suitable temperature.
However adjust the freezer temp. control knob as follows depending upon the storing condition of foods.

(2) Temperature control of refrigerator
Damper-thermostat senses temperature of the refrigerator and changes the opening angle of the damper
automatically.
However, as the Damper-thermostat has no function to switch on or off the compressor and F-fan motor,
the freezer temperature control causes temperature in the refrigerator to vary to some extent.
However, adjust the refrigerator temp. control knob as follows depending upon the cooling condition.

PURPOSE
For making ice rapidly or fast freezing.
When restocking with fresh food.
For normal freezing.
For storing frozen food for a short period (up to one month).
When frozen food or ice cream is not stored.
PURPOSE
For keeping freshness of food longer.
When the refrigerator does not provide sufficient cooling.
For normal operation.
When the refrigerator provides excessive cooling.
When the temperature of the refrigerator is higher, R-fan thermo. senses the temperature and the
refrigerator is cooled efficiently by running of R-fan motor.
R-fan thermo. heater energizes when the door is opened intend to promote to running of R-fan motor.
NOTE: The refrigerator temperature is affected also by the freezer temperature. If the freezer temp. control
knob is set at the position "MAX", the temperature tends to be lower than the following values, and
if set at near the position "MIN", temperature tends to be higher.
If the refrigerator is operated for a long time with the freezer temperature control sets the "MAX"
position, foods stored in the refrigerator compartment may also freeze.
When refrigerator temperature control sets to the "MAX", some foods stored may freeze.
In this case adjust control set back to the "MED" position.
When refrigerator temperature control sets to the "MAX", some foods stored in fresh case may also
become frozen.

The values shown above refer to the measurement carried out center area and 1/3 of overall height from the bottom
at each of the refrigerator and the freezer after machine has been operated at an ambient temperature of 30˚C with no
food stored and the door closed until the temperature is stabilized.
The values vary depending upon frequency of opening and closing the door, ambient temperature, amount of stored
foods and manner of storing foods.

2. DEFROSTING
(1) No defrosting operation is necessary
No defrosting operation is necessary.
As this machine is so designed that a built-in
evaporator cools air and a fan circulates cooled
air, neither the freezer nor the refrigerator is
frosted, though the evaporator is frosted.
(2) Where is melted frost brought
1. Melted frost is brought into the evaporating
pan at the bottom of the set and is evaporated
here by the heat of sub condenser.
2. Be sure that the evaporating pan is inserted
correctly and is level.
The frosted evaporator is defrosted automatically
due to the function of defrosting timer and heater,
requiring no defrosting operation.
(3) The following circuit diagrams in the table show automatic defrosting function of the refrigerator with
timer and defrost thermostat.

The timer contact is changed to start

It takes about 20 to 30 min. to defrost.
When little frosted, the defrosting takes
little time. When much frosted, the defrosting takes much time.
When the defrost thermostat becomes
OFF, the timer motor starts running.
During the operation time (delay time
of defrost time)
defrosted water is
drained outside the refrigerator.

(4) As a reference to determine the causes of trouble, malfunction and phenomena are described below.
Refer to the following when repairing.
1. Disconnection of defrost heater
As off-cycle defrosting is performed, the defrosting time is extremely prolonged. Each time defrosting is
started, the freezer temperature rises and a portion of ice and stored foods are melted.
2. Melted thermo. fuse or opened-circuit due to the defect of defrost thermostat.
When the above mentioned trouble occurs in cooling operation, the timer motor does not run, defrosting
will not take place, and consequently freezing is caused. In the above mentioned condition, when the timer
shaft is turned by hand to defrost, the timer motor runs during the operation time. However, the motor stops
from the time when the contact is changed, and freezing causes.
NOTE:
As the thermo. fuse assembly is intended to prevent dangers, do not use it under shorted condition even
for a short period.
3. DEW PREVENTION
The hot pipe, namely D.P.-condenser, is arranged around the flange part of
cabinet and the C-partition plate, preventing dew from being generated on
the cabinet.
NOTE:
D.P.-condenser pipe may be felt hot if touched by hand while the
compressor is in operation.
If you are asked about this, please explain that the hot pipe serve to
prevent the dew generation.
Hot pipe
4. INSPECTION OF INITIAL STARTING
(1) Inspection of cooling unit
1. Set the temperature control knob to "MAX" and check that the compressor starts to operate.
2. Depress the door switch to run the fan and check that cool air is blown out of the cold air outlet of the
freezer and the refrigerator.
3. When the compressor does not work, check that the timer is not set to "defrost" position.
4It takes about an hour and a half or two hours to put food in the refrigerator after starting operation.
NOTE:
After return the temperature control knob to "MED" position.
When the refrigerator is operated initially after installed, the compressor may vibrate excessively for 1 to 2
min. However, vibration becomes normal if it is continuously operated.
(2) Inspection of defrost device
Operate the refrigerator for 20 to 30 min. and then check the defrost device in the following procedures :
Allow 5 min. to restart the compressor since immediate starting after stopping will cause unsmooth operation.
1. Turn the timer shaft clockwise with a screw driver.
At this time, make certains the timer clinks and the compressor stops.
2. After more than 5 min., turn the shaft further to operate.
Make certain cooling operation is started again.
