START-UP OF UNIT
Use the following procedure to start trial operation or actual operation of the unit.
1.
Connect the power supply cord to the dedicated outlet having appropriate rating with the chamber
empty, and turn on the power switch on the freezer.
2.
Turn on the battery switch.
3.
Set the desired chamber temperature. See page 14 for the temperature setting.
4.
Check that the chamber temperature reaches the desired temperature.
5.
Make sure that the alarm lamp blinks and the buzzer sounds by pressing the alarm test key (ALARM
TEST). The remote alarm is also operated. E09 is displayed on the control panel and buzzer sounds if
the battery switch is off. Make sure to turn on the battery switch.
6.
After confirming the above, you can put articles into the freezer chamber in a small batch to prevent the
temperature rise.
Note:
■
When starting the operation of the freezer for the first time, the alarm lamp (ALARM) lights after the start
of operation. When the chamber temperature reaches around the set temperature, then the alarm lamp
goes out (The remote alarm is not activated).
■
If the battery switch is turned on before turning on the power of the freezer, the temperature alarm is
activated and the buzzer sounds and the remote alarm is also activated after the start of operation.
Check that the battery switch is off before turning on the power switch.
Operation after power failure
The set value is memorized by nonvolatile memory. Accordingly, the freezer resumes the operation with
setting before power failure.
When the freezer is recovered from power failure with the chamber temperature higher than the preset
temperature, then the high temperature alarm is activated and the buzzer sounds and the remote alarm is
also activated. Please push the buzzer stop key (BUZZER) to silence buzzer and take appropriate
actions if needed.
