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 20],
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 to start operation of the unit.
4.
Turn on the battery switch.
Note:
When the battery switch for power failure alarm is OFF, “S20: Battery Inactive, SW may be OFF.” is
displayed in the message display field. By turning ON the battery switch for power failure alarm, this
message disappears.
5.
Set the desired chamber temperature [page 24].
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.
Do the alarm test. Make sure that the buzzer sounds by pressing Buzzer key for 5 seconds. Press
Buzzer key again to stop the buzzer and the alarm test finishes.
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 [pages 24 – 25] and the buzzer suspended period [pages 30 - 31], lock
the menu setting [pages 26 - 28], and set the compressor delay [page 26], and door alarm delay [pages
30 - 31] as required.
Note:
• When closing the outer door push the latch until the latch is locked in place. Insufficient pushing can
lead to temperature rise in the chamber.
• In case some optional inventory racks are in the chamber, be careful not to drop inventory rack when
pulling out it.
