START-UP OF UNIT

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

1.Make sure that all the switches on the control panel, such as the power switch, the remote alarm switch, the back-up system switch are off.

2.Liquid CO2 gas cylinder is set at this time.

3.Shut the door and connect the power cable to the power supply after the inner lid is installed.

4.Turn on the power supply switch and the temperature is displayed on the digital indicator.

5.Set the desired chamber temperature by using the keypads on the control panel. Do not set the chamber temperature at lower than -90oC.

6.Set the temperature at which the back-up system activates according to the procedure on page 21 when the temperature display pointer of temperature recorder corresponds with the desired temperature if the back-up system is used.

7.Switch on the remote alarm switch and back-up system switch.

8.Check that the alarm lamp lights and the buzzer sound by pressing the alarm test key.

9.Make sure that liquid CO2 spouts into the chamber by pushing the back-up test switch.

10.Now you can put articles into the freezer chamber. Switch off the remote alarm switch and the back-up system switch temporarily when putting in a lot of warm articles. Switch on these switches again after a certain period of operation.

Operation after power failure

The set value is memorized by nonvolatile memory in the event of power failure. Accordingly, the freezer resumes the operation with setting before power failure.
