START-UP OF UNIT
Follow the procedures for the initial and consequent operations of the unit.
1.
Turn the power switch ON with the chamber empty.
2.
Turn ON the battery switch.
3.
Set the chamber temperature to a desired value.
4.
Allow the unit to achieve the desired chamber temperature.
5.
Check that the alarm lamp is flashed and the buzzer is activated by pressing alarm test key (ALARM
TEST). The remote alarm is also operated. E09 is displayed on the control panel if the battery switch is
OFF.
6.
Now you can put articles into the chamber gradually to minimize the temperature rise.
Note:
When starting the operation of the freezer for the first time, the alarm lamp (ALARM) is flashed. When
the chamber temperature reaches around the set temperature, then the alarm lamp goes out (The remote
alarm is not activated).
If the buttery switch is turned ON before turning ON the power of the freezer, the power failure 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 freezer.
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.
