START-UP OF UNIT
Follow the procedures for the initial and consequent operations of the unit.
At the recovery after power failure, the operation is start-up automatically with the setting before power
failure. See page 20.
1.
Connect the power supply cord to the dedicated outlet with appropriate rating.
<Important>
If the unit is unplugged or the power to the unit is interrupted, do not restart the unit for at least 5 minutes.
This protects the compressor.
2.
On start-up, the alarm buzzer sometimes operates. In this case, stop the alarm buzzer by pressing
the alarm buzzer stop key (BUZZER). (This is not a malfunction.)
<Important>
Close the door securely. The door check indicator is lit when the door is open. The alarm buzzer
activates when the door is opened for more than 2 minutes. The alarm is canceled when the door is
closed.
3.
Allow the chamber temperature to fall to
5
o
C (The chamber temperature is set to 5
o
C at the factory).
Check the chamber temperature on the temperature display.
4.
Switch on the light switch to check the fluorescent lamp is on. After checking, turn off the fluorescent
lamp if the light is not necessary.
5.
Set the desired chamber temperature. See page 14.
6.
When the chamber temperature gets to the set temperature, begin slowly placing items into the
chamber to minimize the temperature rise.
<Important>
Always put the items on the shelf or in the drawer, not on the bottom of the chamber. Do not contact the
items to the chamber walls.
Do not block the air intake vent nor air exhaust vent. Place the items with adequate space between
them to keep the cool air circulation.
