The power of an automatic cooling auxiliary device uses a chargeable
battery (lead storage battery). The life of a battery is approx. 3 years.
Inquire of a store where a user bought it for replacement.
Install it where sufficient ventilation is possible. Ensure to ventilate since
there is a risk of hypoxia or gas poisoning due to N2 gas discharge while an
automatic cooling auxiliary device is running.
In addition, even when an auxiliary cooling device is not running, N2
evaporation gas is generated. Always ventilate the installation place.
3. Common use of alarm buzzer, alarm lamp
The alarm buzzer and the alarm lamp of the product with an automatic
cooling auxiliary device use the alarm in common as 5-type alarm system.

temperature of a freezer rises while running by +15
°
C or above than the setting temperature.
Ex.: Where the set inner temperature of a freezer is -150
°
C, an alarm boozer goes off at -135
°
C
(alarm boozer 1)
②
Freezer overload

③
Fan motor anomalies
Where a fan motor lacks rotation or stops,
alarm boozer 1 goes off and AL-2 lamp (red) is on.
④
The Automatic cooling auxiliary device runs (anomalies of freezer inner temperature above -130°C)
If the inner temperature of a freezer is above -130°C while
BACKUP SYSTEM
switch is on,
an alarm boozer goes off (where LN2 cylinder is correctly connected, LN2 sprays into a freezer).
