DEFROST OF EVAPORATOR
The following 2 kinds of defrost methods are provided with this refrigerator. Both defrost methods are
controlled automatically.
Cycle defrost
To keep the chamber temperature stable, the refrigeration compressor is cycled on and off. During “off”
period any frost which has accumulated on the evaporator is melted by energizing a defrost heater. This
will not have any discernible effect on the chamber temperature.
Forced defrost
When the ambient humidity is high, or a large amount of damp product is being stored inside the chamber,
there is a possibility that cycle defrost may not be enough to remove all of the frost on the evaporator. In
this case, a forced defrost cycle can be initiated.
When the unit is operating under a forced defrost cycle, the current chamber temperature and dF is
displayed alternately on the temperature display.
Once the forced defrost cycle is completed, normal operation resumes.
CAUTION
The unit may collect excessive frost on the evaporator
if it is installed in high temperature and high
humidity location. For example, the unit starts to defrost once a week with 2
o
C setting in the ambient of
35
o
C and 80 %R.H.
The chamber temperature goes up to approximately 10
o
C temporarily during
defrosting.
