• Keep an electric product which emits an electromagnetic wave away from this unit. A noise from an
electromagnetic wave may cause malfunction to this unit.
□ The unit is not connected to the power supply properly.
□ The capacity and voltage of the power supply is not sufficient.
□ There is a power failure.
□ The circuit breaker on the supply circuit is activated.
□ The fuse on the supply circuit is blown.
□ The capacity of power supply is not sufficient. When the capacity of
power supply is not sufficient to start the compressor, compressor may
not start.
□ The chamber temperature setting has been changed.
□ The door has been kept open for a long time.
□ Containers with a high temperature (load) have been put in the

with dew. Under a high humidity environment, the cold exterior of the
unit condenses the moisture in the air, so that it is not malfunction. Wipe
the dew with a dry cloth.
As a result of the nature of the cooling circuit, the sound of the motor or
of flowing refrigerant may be heard during operation. In particular, a few
hours after starting operation, the sound of the compressor or of flowing
refrigerant may be loud. However, this is part of the normal operation.
