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.
1.
Check the circuit breaker switch is ON.
2.
Connect the power supply cord to the dedicated power source with the appropriate rating with the
chamber empty.
3.
Press the standby key on the control panel for more than three seconds.
►The home screen (temperature display screen) is displayed. The red LED lamp blinks. (This is caused
by the high-temperature alarm function and is not a malfunction.)
4.
Turn on the battery switch of power failure alarm (when the optional battery kit for power failure alarm
is installed).
“S02:Battery Err” is displayed and the buzzer sounds when the battery switch of power failure alarm is
OFF. The message disappears and the buzzer stops when the battery switch of power failure alarm is
turned ON.
5.
Set the date and time displayed on the temperature display to the current date and time [pages 50 to
51].
6.
Set the desired chamber temperature [page 22].
The factory setting of refrigerator chamber temperature is 5
o
C .
7.
Open the door to check that the interior light is on.
8.
Using the temperature display, check that the chamber temperature has cooled to the set temperature.
9.
Gradually place the material inside the chamber.
Putting a large amount of material into the chamber at one time causes the temperature to rise.
Do not block the air intake vent nor air exhaust vent in the chamber.
10.
Set a selectable parameter (keypad lock, alarm temperature, delay of door alarm buzzer, etc.) as
required [page 21].
AFTER RECOVERY FROM POWER FAILURE
After recovery from a power failure, the operation will resume automatically with the same settings as
before the power failure. There is no need to re-set. However, always check the operational status
after recovery.
The settings are memorized during power failure by nonvolatile memory.
