1. ADJUSTABLE TEMPERATURE CONTROL
(1) Temperature control of freezer

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

Figure F-1.

(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 cool air
circulating fan, 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.

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 fresh
cases 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.
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 to use the evaporating pan as inserted
so as to be level with the outer case.

(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. Cooling (start)

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 at rest starts running.
During the operation time (delay time of
defrost timer), 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 moter
starts running. (Figure F-4.)

The timer contact is changed to start

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.

(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.

Figure F-8.

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 two or three hours to put food in the refrigerator after starting operation.

NOTE:

Return the temperature control knob to "MED" position afterward.
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.

DEODORIZING OPERATION

Deodorization is performed with the aid of a deodorizing heater which uses a conventional glass pipe heater having a
deodorizing function.

1. Operation

The deodorizing system is arranged in the cool air passage, so that deodorization effect is always maintained.
Therefore, any operation is not necessary.

2. Component Parts and Deodorizing Principle

(1) This deodorizing heater uses the porous catalyst layer laid on the surface of radiant heater glass pipe (high-

quality quartz glass). The deodorizing catalyst consists of zeolite, alumina, silica, noble metal, and rare-earth
oxide. It adsorbs and decomposes the following odors.
It adsorbs:
Stench odor evolved from vegetables and fruits ... Methyl mercaptan,
Stench odor evolved from meats and fishes ... Trimethylamine,
Stench odor evolved from fermentation foods ... Aliphatic acids.
The noble metal and rare-earth oxides act as catalysts which oxidize and remove the adsorbed stench
ingredients at a temperature of over 250˚C.

(2) In normal cool state, this deodorizing heater adsorbs the stench ingredients. In defrosting state where the

heater is heated, it oxidizes and removes the adsorbed stench ingredients by a catalysis.
