PRECAUTIONS AND ACTION FOR TEMP. RISE
Action for chamber temperature rise
When the high-temperature alarm or power failure alarm (when the battery mounting box battery is
installed) has been activated (in which case, the alarm indicator blinks and the buzzer sounds) as a
result of an unforeseen event, take the action described below without delay to protect the storage
item.
Checking the causes and taking the necessary action
<Important> Check the cause of the temperature rise and take action without delay to deal with
the cause. (“Action for alarm” [page 33])
If the alarm fails to stop or the chamber temperature fails to drop even after one hour, a machine
malfunction may have occurred. Contact our sales representative or agent without delay.
Transfer the storage items to another refrigerator and freezer.
Action when the product has stopped due to a power failure
If a power failure is responsible for the rise in temperature, check the recovery time from the power failure,
and take the appropriate action in accordance with the expected recovery time.
<Action to take when the power failure is of short duration (several minutes to up to one hour)>
Do not open the doors as this will cause the chamber temperature to rise.
Reduce the ambient temperature to 25 °C or below.
<Action to take when the power outage is of long duration (one hour or more)>
Transfer the storage items to another refrigerator and freezer.
Provide a back-up power source if no other refrigerator and freezer are available.
