3.9.4 Water Drainage
i. The water drainage adapter in the
drawer should be cleaned every 6
months to 1 year to keep it from being
obstructed. This avoids poor drainage
and refrigeration.
ii. The water drained from the refrigerator
is drained into the evaporation pan
from the drainage system.
iii. Water in the evaporation pan shall be
duly evaporated by the radiator. There
is no need to remove it.
iv. After some time, dust or impurity
builds up in the evaporation pan and
produces odor. This should be
cleaned once a month.

V. FUNCTIONS
5.1 DEFROSTING
5.1.1 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.
5.1.2 Where is melted ice brought?
i. Melted ice is brought into the
evaporating pan at the bottom of
the set and is evaporated here by
the heat of sub condenser.
ii. Be sure to use the evaporating pan
as inserted so as to be level with
the outer case.

Page 19
V. FUNCTIONS
5.1.3 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) ·Defrost thermostat ON
·Compressor running
·Timer motor running
Figure F-1
The integration timer
integrates running time of
the compressor. When it
reaches 8 hours 50 min. at
50Hz (10 hours 50 min at
60Hz), the timer contact is
changed to start
defrosting.
2. Defrosting
(Time 20 to 30 min)
·Defrost thermostat ON
·Compressor stops
·Timer motor stops
Figure F-2
·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.

V. FUNCTIONS
Operation Electric diagram Description
3. Drain
(Time approx. 3 min)
·Defrost thermostat OFF
·Compressor stops
·Timer motor running
Figure F-3
When the defrost
thermostat becomes OFF,
the timer motor at rest
starts running. During the
operation time (2 min. 48
sec./50Hz; 2 min/ 60Hz)
defrosted water is drained
outside the refrigerator.
4. Cooling start
(Time approx. 5 min)
·Defrost thermostat OFF
·Compressor running
·Timer motor stops
Figure F-4
·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-1)
