ALARMS AND SELF-DIAGNOSIS

Warning The cooling performance is significantly reduced. The chamber temperature may get higher
:
considerably. Take some precautions for the storage items immediately (transferring the storage items
to another freezer or placing of dry ice wrapped in newspaper in the chamber) except when the cause is
clear and the chamber temperature can be recovered soon.
Contact our sales representative or agent after turning off the power switch.

1: The compressor stops in the case of W02 or W03.
*
2: The compressor runs continuously in the case of W09 or W10.
*
The compressor stop has a priority over the continuous running if the above two errors come up at one time.
3: The chamber temperature is not displayed in the case of W08
*
Alarm Cooling performance may decline and the temperature of the chamber may rise. Wait for the
:
recovery of chamber temperature if the temperature change is temporary resulting from user operation.
For other cases, failure or chamber temperature rise may cause if this status continues.
Take some precautions for the storage items (transferring the storage items to another freezer or
placing of dry ice wrapped in newspaper in the chamber).
Contact our sales representative or agent.
