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.

CAUTIONS AND INFORMATIONS

1. Some foods freezed in the refrigerator compartment.

2. Some plastic parts were cracked or splitted.

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).

3. IT IS NORMAL for the refrigerator to produce the following sounds.

Do not place food directly in front of

cold air outlet.

This may lead to the food freezing.

OUT

cold air flow

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.

SJ-2060 FUNCTIONS

1. ADJUSTABLE TEMPERATURE CONTROL

(1) Temperature control of freezer

Thermostat (senses freezer temperature) operates on ON/OFF switchover to control the compressor and

coolair circulating fan(F-fan motor) ,and allows thefreezer temperature tokeep at a suitabletemperature.

However adjust the freezer temp. control knob as follows depending upon the storing condition of foods.

KNOB

MAX

(Coldest)

MIN

PURPOSE

For making ice rapidly or fast freezing.

For storing frozen food for a short period (up to one month).

When frozen food or ice cream is not stored.

For normal freezing.

REFRIGERATOR TEMP. CONTROL

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.

The values shown above refer to the case where the 

freezer temp. control knob is set at "MED".

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 "CHILLED ZONE", some foods stored may

freeze.

In this case adjust control set back to the "MED" position.

When refrigerator temperature control sets to the "CHILLED ZONE", some foods stored in chilled

case may also become frozen.

(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.

(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.

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.

(3) The following circuit diagrams in the table show automatic defrosting function of the refrigerator with

timer and defrost thermostat.

Operation Electric diagram Description

1. Cooling

(Normal)

2. Defrosting

(Time 20 to 30 min.)

3. Drain

(Time approx. 5 min.)

4. Restart

(Time approx. 5 min.)

The integration timer integrates running

time of the compressor. When it reaches

cycle time of defrost timer, the timer

contact is changed to start defrosting.

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.

Timer contact is changed to cooling

operation and the compressor starts

running and the timer motor stops.

Defrost thermostat contact becomes ON

when it’s cooled. And the timer motor

starts running. (Figure F-3.)

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 def-

rosting takes much time.

(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

shaftis turned byhand todefrost, the timermotor runs duringthe operation time.However, the motorstops

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

Thehot pipe, namely D.P.-condenser, is arranged aroundthe 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.

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.
