1. ADJUSTABLE TEMPERATURE CONTROL
(1) Temperature control of freezer
Thermostat(freezertemperaturesensingthermostat)operatesonON/OFFswitchovertocontrolthecompressor
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.
FUNCTIONS
Thevalues tables above referto themeasurement carriedout centerarea and1/3 ofoverall heightfrom thebottom ateach
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.
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
knobis set attheposition "MAX", the temperaturetendsto be lower thanthefollowing values, andif 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.

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 ice brought
1. Meltediceis brought intotheevaporatingpanat
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.

2. Defrosting
(Time 20 to 30 min.)
3. Drain
(Time approx. 5 min.)
4. Cooling (start)
(Time approx. 5 min.)
The integration timer integrates running
time of the compressor. When it reaches
10 hours 50 min. at 50Hz, 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(4 min. 20 sec.
/50Hz) 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. (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
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
Asoff-cycledefrostingisperformed,thedefrostingtimeisextremelyprolonged.Eachtimedefrostingisstarted,
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.
Whentheabove mentioned trouble occursin cooling operation,the timer motordoes notrun, defrosting willnot
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.-condenserpipemaybefelthotiftouchedbyhandwhilethecompressor
is in operation.
Ifyou are asked aboutthis, pleaseexplain thatthe hotpipe serveto prevent
the dew generation.
Figure F-7.
4. INSPECTION OF INITIAL STARTING
Hot pipe
(1) Inspection of cooling unit
1. Set the temperature control knob to "MAX" and check that the compressor starts to operate.
2. Depressthedoor switch to runthefanandcheckthatcool air isblownoutofthecoldair outlet ofthefreezerand
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.
NOTE:
It's not necessary to switch the timer by changing of source frequency (50Hz, 60Hz).
