START-UP OF UNIT
Follow the procedures for the initial and consequent operations of the unit.
1.
Check that the power switch and battery switch are OFF.
2.
Connect the power cord to the dedicated outlet having appropriate rating with the chamber empty.
3.
Turn on the power switch.
Note:
The alarm buzzer operates until the chamber temperature reaches the set temperature if the power switch
is turned on with the battery switch is ON.
4.
Turn off the power switch of the Backup cooling kit (optional component) if it is installed.
5.
Turn on the battery switch.
6.
Set the chamber temperature to the desired temperature.
7.
Allow the chamber temperature to fall to the desired temperature. Check the chamber temperature on
the digital temperature indicator.
8.
Turn on the power switch of the Backup cooling kit (optional component) if it is installed.
9.
Press the alarm test key (ALARM TEST) and check that the alarm lamp blinks and alarm buzzer
activates.
10.
After confirming the above, you can put articles into the freezer chamber in a small batch to prevent
the temperature rise.
Operation after power failure
The settings (chamber temperature, alarm temperature) are memorized by nonvolatile memory during the
power failure. Accordingly, the freezer resumes the operation with setting before power failure.
In some cases, the condensing fan may not operate to improve the cooling performance. This does not
mean the malfunction.
At the start-up: the fan starts to run with more than 30 minutes delay when the ambient temperature is
lower than 20
o
C.
During the normal operation: the fan may not operate when the ambient temperature is lower than
20
o
C.
