Event logs are recorded when specific conditions occur, and can be
used to store certain related values, as shown in the table below.
The type of alarm recorded in the log can be identified using the
alarm code (see "8.1 Error codes: Overview" [ 4 18]).

* The samples are stored in a circular FIFO list (e.g. for the alarms,
the 21st alarm overwrites the first alarm, and so on).
NOTICE
Changing the time set on the controller by more than
140 minutes will clear the stored logs.
The alarm log can be deleted using parameter rAL, accessible via
the user terminal, configuration tool or in the Daikin User (Bluetooth
connection only) using the specific command on the alarms page
("Service" or "Manufacturer" level access is required).
INFORMATION
Deleting the alarm log is irreversible.
For the alarm list with the codes and descriptions, see "8.1 Error
codes: Overview" [ 4 18].

Operation procedure

▪ Read the documentation carefully before operating the unit to
ensure the best possible performance.
▪ Turn ON the unit before storing the refrigerated goods. Varies
from 15 to 30 minutes, depending on the ambient temperature.
▪ Choose the correct temperature setting for the product that is to
be stored (see "4 User interface" [ 4 6]).
NOTICE
Check the evaporator condition 24 hours after starting. If
ice has formed, the defrost frequency should be increased.
In low temperature units the evaporator condition should
be checked every week during the first month of operation.
▪ A door micro switch interrupts the unit operation and turns on and
off the cold room when the cold room door is opened. The cold
room lamp can also be switched on and off via the user interface.
▪ Bluetooth makes it possible to check and control the unit via the
Daikin User app.

▪ Multiple units (up to 5) can be combined within one cold room.
They will then operate according to the primary/secondary
principle.
Advantages:
▪ Higher cooling capacity.
▪ Redundancy should a unit break down.
▪ Better airflow.

Storing the goods

NOTICE
Do not cover the air intake and -outlet openings towards
the condenser and evaporator of the unit.
Maintaining the right temperature guarantees the preservation of the
quality of the stored goods.
Air circulation is of absolute importance to keep a uniform
temperature throughout the entire cold room. Insufficient air
circulation can cause heat pockets or ice formation.
For this reason:
▪ Use pallets or racks that facilitate air circulation under the goods.
▪ Place the goods away from the cold room walls. Use spacers if
necessary.
▪ Leave a space of approximately 20 cm between the goods and
the cold room ceiling.
▪ Stack heat generating products, such as fruit and vegetables, in a
way to create sufficient space to remove the generated heat by
cold air circulation.
▪ Stack products which do not generate heat, such as meat and
frozen foods, close to each other toward the center of the cold
room.
WARNING
Make sure that no people are left in the cold room before
you close the doors:
▪ Risk of suffocation. 12 m
cold room.
▪ Risk of frostbite.
▪ Risk of freezing to death.
