About defrosting of the refrigerator
3 Setting the refrigerator operation mode of the refrigerator (continuous & cycle)
The refrigerator operation mode is a function that enables continuous operation, cycle operation
or stopping the refrigerator.
Continuous operation is used when temperature control precision is important. Note that frost
tends to form the more the lower the temperature is at the set temperature range of 0
~
30
℃
.
Cycle operation controls by repeating the sequence: operation of the refrigerator (14 minutes)
→
pause (six minutes) and has less temperature control precision compared with the continuous
operation but is able to reduce frosting. Note that the refrigerator enters the continuous
operation mode automatically because of the freezing capacity reasons when the set
temperature is 10
℃
or lower. (When the refrigerator is set at Stop, it will not operate irrespective
of the set temperature.
)
Drying of specimen can be reduced by performing the cycle operation. Set the refrigerator to
Stop if its operation is unnecessary. (The refrigerator will automatically set to stop irrespective of
the select operation mode when the set temperature is 40.1
℃
or more.
)

See page 15 for operating procedures.
Caution
●
Even when the cycle operation is set, forming of frost may gradually increase during a long
time of operation depending on the operating conditions. When a lot of frost is formed,
perform defrosting operation or cycle defrosting operation to remove frost. Be sure to put a
drain pan to accept water of melted frost at the drain hose.
