2. Performance of defrost operation
When setting temperature at 25
℃
for defrost
operation and the operation is continued for 20
minutes, it stops automatically and the temperature
inside the chamber returns to the setting temperature
that was active when the control operation was
stopped, or control operation before defrosting will
restart.
If the defrost operation is executed immediately after
the refrigeration unit stops, you need to wait 80
seconds until it restarts and hot gas flows into it. This
is a timer for protection of refrigeration unit.
*Even if the temperature inside the chamber does
not reach to 25
℃
(defrost temperature),
the operation stops automatically after elapsing
20 minutes.
3. Manual stop of Defrost operation
If you would like to stop manually while
operating defrost, press [Defrost] key again.
Turn on [Water Supply] key.
The water is supplied into the internal tank from
