START-UP OF UNIT

Follow the procedures for the initial and consequent operations of the unit.

1.Turn off the switch of the back-up system (optional component) if it is installed.

2.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.

3.Turn on the battery switch.

4.Set the desired chamber temperature. See page 14 for the temperature setting.

5.Check that the chamber temperature reaches the desired temperature.

6.Turn on the switch of back-up system (optional component) if it is installed.

7.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 digital temperature indicator if the battery switch is OFF. Make sure to turn on the battery switch.

8.After confirming the above, you can put articles into the freezer chamber in a small batch to prevent the temperature rise.

9.An alarm function is to work normally, or push and confirm an alarm test key (the condition that a battery switch is on). It is normal if alarm lamp blinking, remote alarm operation and a buzzer ring.

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.
