START-UP PROCEDURE
To commence the operation (initially or after temporary power off due to the cleaning, maintenance,
etc.), follow the procedure below:
The operation is resumed automatically at the recovery from power failure with the setting before power failure
[
page 20]
.
1.
Check the power switch is OFF.
2.
Check that the power switch of battery kit for power failure alarm (option) is OFF if the battery kit for
power failure alarm is installed.
3.
Connect the power supply cord to the dedicated power source with the chamber empty.
4.
Turn on the power switch.
►
At the power on, the high temperature alarm is activated. The alarm indicator blinks and the blinking
refrigerator temperature is displayed.
At the start-up with the factory setting, the high temperature alarm is activated when the refrigerator
temperature is higher than 10
o
C, therefore the high temp. alarm works (High temp. alarm; chamber temp. blinks,
alarm indicator blinks, buzzer sounds after 15 minutes)
5.
Set the desired chamber (refrigerator and freezer) temperature [page 21].
The factory setting of refrigerator temperature is 5
o
C and the freezer temperature is -30
o
C.
<Important> Allow 5 minutes before turn on the power switch when the power switch is off. That
is a time for compressor to start-up again.
<It takes about 2.5 hours to reach the set temperature (ambient temp.; 30
o
C, no load, without containers)>
6.
On the temp. display, check the chamber temp. reaches the set temperature.
7.
Turn on the power switch of battery mounnting box (option) if the battery mounting box is installed.
8.
By opening the refrigerator door, check the chamber lamp is on.
9.
Put the material in the chamber gradually. [page 19]
Putting a large amount of material in the chamber at a time causes the temperature rise.
Never block the air intake vent or air exhaust vent in the refrigerator.
10.
As needed, set the alarm temp. [page 26 to 29], buzzer suspended period [page 30], and the lock of
chamber temperature setting [page 22].
<Attention> The condensation may be found on the glass of refrigerator door under high
temperature and humidity condition. Wipe off the condensation with a soft dry cloth.
CAUTION
It is recommended to install a temperature recorder (option) to
check the highest/lowest chamber temperature when the item
which needs severe temperature control is stored.
