FUNCTIONS
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.

Figure F-2.
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.

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.
The frosted evaporator is defrosted automatically
due to the function of defrosting timer and heater,
requiring no defrosting operation.
(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.
(3) The following circuit diagrams in the table show automatic defrosting function of the refrigerator with
timer and defrost thermostat.

2. Defrosting
The timer contact is changed to start
defrosting, the timer motor stops, and
power is supplied to the defrost heater.
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.

running and the timer motor stops.
Defrost thermostat contact becomes ON
when it’s cooled. And the timer motor
starts running. (Figure F-3.)

(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 Hot pipe
prevent the dew generation.
Figure F-7
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.
4 It 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.

5. PLASMACLUSTER (Only for SJ-P60M,P65M,P70M)
(1) Plasmacluster is what thing.
The ionizer inside the refrigerator will release cluster ions, which are collective mass of positive and negative
ions, into the the freezer and refrigertor compartments.
The cluster ions reduce airborne fungus.
(2) Plasmacluster Panel
1.When the refrigerator will be operated, the Plasmacluster lamp of the
panel will ight up.
2.By pushing the button, the lamp gose out or lights up.
3.Under the lamp is lighting, Plasmacluster operation is controlled as
follows.

(3) Plasmacluster Control.
1.Plasmacluster operation will be performed when the following conditions
gather.
1) Lamp : Under lighting
2) Compressor : Under operation
3) Door : Closed
4) Within "The Plasmacluster operation time".
2.If the sum total of Plasmacluster operation time will reach at the set time ("The Plasmacluster operation Time") ,
Plasmacluster operation will stop.
3.After an operation stop, the Plasmacluster will be not operated during the set time ("The Plasmacluster operation
compulsive stop time") .
