START-UP OF UNIT

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

1.Connect the power cord to the dedicated outlet having appropriate rating with the chamber empty.

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

3.Check that the battery switch is ON.

4.Set the chamber temperature to the desired temperature.

5.Allow the chamber temperature to fall to the desired temperature. Check the chamber temperature on the temperature indicator.

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

7.Press the alarm test key (ALARM TEST) and check that the alarm lamp blinks and alarm buzzer activates.

8.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.

The condensing fan does not operate for more than 30 minutes after start-up.

The condensing fan may not operate during normal operation when the ambient temperature is lower than 20oC. This does not mean malfunction.
