CHANGE OF COMPRESSOR DELAY TIME
The delay time of the compressor can be changed to reduce the load on the power line and to facilitate the
start-up (reset) of the freezer after power failure.
The example in the table is based on the assumption that the delay time is changed to 4 minutes.
The delay time is set in 3 minutes at the factory.
Note:
■ The setting range for delay time is between 3 and 15 minutes. The cool down of chamber temperature
may be slow when the setting of delay time is over 5 minutes, depending on the installation environment.
There is no need of changing the delay time when the capacity of power source is adequate.

• The compressor starts to run with the delay time when the power supply cord is connected to the outlet
or after power failure.
• The compressor delay time set mode returns to the temperature display area mode automatically when
90 seconds has passed without any key operation.
