START-UP PROCEDURE
Follow this procedure for the initial operation of the unit and for consequent operations (after temporary
stoppage for cleaning, maintenance or moving) .
After a power failure, the unit will restart operation automatically with the same settings as before the
power failure [page 18]
1. Check that the following switches are turned off: [power switch, battery switch, switch of the optional
back-up cooling kit (if installed)] .
2. Connect the power supply cord to the dedicated power source with the appropriate rating with the
chamber empty.
3. Turn on the power switch .
►When the power is switched on, the high-temperature alarm is activated. The alarm indicator and the
temperature display blink. (This is not a malfunction.)
The high-temperature alarm will be cancelled when the chamber temperature reaches the approximate
set temperature [(factory setting): -80
o
C].
4. Turn on the battery switch.
<Important>
Always turn the battery switch on when the unit is operating to ensure that the power-failure alarm is
working.
5. Set the desired chamber temperature [page 22].
The factory setting of chamber temperature is -80
o
C.
6. Using the temperature display, check that the chamber temperature has cooled to the set temperature.
Check that the chamber temperature falls to the set temperature when the start-up after cleaning,
maintenance or moving.
7. Turn on the switch of the optional back-up cooling kit (if installed).
8. Press the buzzer stop key (BUZZER) for 5 seconds to check the alarm operation.
►The alarm lamp blinks and the buzzer sounds. The remote alarm is also operated.
“Error E09: Battery switch is off” appears on the message column if the battery switch is off.
9. Press the test switch of the optional back-up cooling kit (if installed) to check it is working.
10. Gradually place the material inside the chamber.
Putting a large amount of material into the chamber at one time causes the temperature to rise.
11. Set the alarm temperature [page 22] and others as required.
