Connect unit to dedicated power supply and turn on the power switch. Do not put any product in the
unit at this time.

NOTICE
Door alarm by opening and closing the door
1.
When the door is opened and remains open for less than 3 minutes and items are removed or replaced
gradually, the alarm will not be activated. But if the door is frequently opened or remains open for a long
time or many items are put in at the same time, the alarm will be activated. The alarm may also be
activated after replacing items and closing the door. This does not denote a malfunction. It is caused
by the circulation fan stopping while the door is open and starting when the door is closed.
2.
When the alarm is activated, run the unit until the temperature indicator needle falls below the upper
limit (generally it takes 10 to 30 minutes). Reset by turning the alarm switch off and turning it on again.
The buzzer switch can be turned off while you are waiting for the temperature drop. After the chamber
temperature falls to adequate value, be sure to turn on the buzzer switch again.
Adjustment of shelves
The shelves can be adjusted to the height of items place
inside. To adjust the height, insert the shelf support into
the slots at the desired height.
