This unit is for storage of samples. When loading samples into the freezer, the samples must
be precooled. If a user load plenty of the samples, which have Room temperature into the
freezer, the temperature will go up temporarily and an alarm may go off. When storing the
samples of Room temperature in a freezer, load small amount of samples several times to
prevent overheating and high temperature alarm. When a user load plenty of cold storage
packs or cold insulation material into a freezer, the same state will occur. Cold storage packs
or cold insulation material has the merit of keeping the low temperature environment for a long
time, but requires considerable amount of time in cooling, so if a user load big amount of
warm samples in the freezer, such will cause a lot of heat to the unit.
• The battery for Power failure alarm is consumable. The life is 3 years after
installation. When the battery is out, an alarm buzzer will not sound even upon power
failure, which may affect the samples adversely. We recommend that a user should
check the battery regularly and exchange in advance. Purchase of the Battery can be
done locally.
How to check the buzzer.
A buzzer will sound when POWER switch is off while AL-1 switch is ON.

remote alarm system. All is equipped with On/Off switches, so use it as necessary.
The temperature increase alarm sounds under the following conditions.
• AL-1 switch is ON
• The inner temperature of a freezer (PV) is +15°C compared with
the set point temperature (SV)
In case of the first use, the alarm will sound, caused to the inner temperature of a
freezer is too high. After reaching stable temperature, turn on the AL-1 switch.
The Power failure alarm sounds under the following conditions.
• AL-1 switch is ON
• Occurrence of Power failure or equivalent incident (plug is pulled out of the wall
socket or the power switch is off)
An alarm buzzer sounds for about 48 hrs. continuously even when an electric current
is not applied. Limited to the case of sufficient charging (after operation for min. 5
days). The life of a battery is approx. 3 years.
The remote alarm signal output will be activated under the following conditions.
• REMOTE switch is ON (output even when AL-1 switch is OFF)
• The Alarm delay is the same as the high temperature alarm and power failure.
• The remote alarm connector of the external alarm is Off (open) when no Alarm is
present, when there is an Alarm activated, the contact will be closed.
Where there is an electrical anomaly in the double cooling system. Breakdown of the
Compressor, AL-2 lamp (red) turns on. In addition, where AL-1 switch is ON, a buzzer
sounds interworking with AL-2 lamp.
When only one cooling system is running, the Temperature in the Freezer can be kept
under -130°C.
