3. 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
1. Cooling
(Normal)
2. Defrosting
(Time 20 to 30 min.)
3. Drain
(Time approx. 5 min.)
4.Restart

(2) Where is melted ice brought
1. Melted ice is brought into the evaporating pan
at the back of the set and is evaporated here
by the heat of compressor.
2. Be sure that the evaporating pan is inserted
correctly and is level.
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.

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 take
little time. When much frosted, the def-

rosting takes much time.
When the defrost thermostat becomes
OFF, the timer motor starts running.
During the operation time
(delay time of defrost timer)
defrosted water 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-19)
