Return after power failure
When power is supplied after a power failure, the device automatically starts operation again with
the same state as just before the power failure. It is danger that the device starts unattached
operation after a power failure. We recommend for you to turn off the switch of this unit if a
power failure occurs during operation.
In-oven temperature
This unit uses a cooling fan to prevent an over temperature of its outer surface during operation
when the earth leakage breaker is turned ON. Do not turn OFF the interrupter, or do not
disconnect the power supply plug directly when the in-oven temperature is 600
℃
or more after
operation, except in the case of emergency.
Provide ventilation at the first operation
This unit exhausts smoke and smell due to burning of organic matters in the furnace when it is
used for the first time. This is not abnormal, but ventilating inside the room should be done.
