Specific alarms
There are specific alarms for controlling the operating temperature,
recording any anomalies due to power failures or an increase in the
temperature due to other causes (breakages, extreme operating
conditions, user errors, etc.).
Two types of potentially critical HACCP events are managed:
▪ Type "HA" alarms, high temperature during operation:
The type "HA" alarm is generated if during normal operation the
temperature read by the control probe exceeds the high
temperature threshold for 60 minutes (delay time for high and low
temperature alarms) + "Htd" (HACCP alarm delay). Consequently,
compared to the normal high temperature alarm already signalled
by the controller, the type "HA" HACCP alarm is delayed by a
further time "Htd" specifically for HACCP recording.
Example: The critical temperature was exceeded, the alarm was
not managed and the temperature remained above the threshold
for longer than the maximum tolerable time (thresholds defined by
site HACCP procedures).

▪ Type "HF" alarms, high temperature after power failure:
The type "HF" HACCP alarm is generated following a power
failure, if when power returns the temperature read by the control
probe exceeds the "AH" high temperature threshold. "HFn"
indicates the number of type "HF" alarms activated.
Example: The unit was powered off. When restarted, the
temperature is above the threshold and does not return to an
acceptable level within an appropriate time (parameters defined
by site HACCP procedures).

When an alarm occurs, the HACCP icon comes on, the display
shows the alarm code, the alarm is logged and the alarm relay and
buzzer are activated.
The "HA" and "HF" alarms can be reset using the Daikin app. See
"4.5.3To reset an alarm or warning"[416].
The HACCP event log can be deleted by using the Daikin app, via
the drop-down menu on the side, selecting "Alarms -> Alarm history
-> Clear logs".
NOTICE
Deleting the HACCP event log is irreversible.

Energy saving and optimum
operation
If circumstances allow:
▪ Do not place unfrozen liquids or foodstuffs in the cold room (when
used as freezer).
▪ Reduce the opening frequency of the cold room doors.
Always:
▪ Reduce the opening time of the cold room doors.
▪ Make sure that cold room doors are perfectly tight.
▪ Make sure that a good airflow is possible between the stored
goods.
▪ Check that the evaporator is ice-free. Ice forms on the evaporator
preventing air from flowing regularly.

Maintenance and service
INFORMATION
Suitable maintenance is crucial for obtaining longer life,
perfect working conditions and high efficiency of the unit. It
also ensures the proper functioning of the safety devices
provided by the manufacturer.
7.1
Cleaning the unit
7.1.1
To clean the exterior
NOTICE
To clean the unit enclosure:
▪ Do not use any cleaning agents or chemicals.
WARNING
Do NOT use water for cleaning. Use of water can damage
electrical components.
Clean with a soft cloth. If it is difficult to remove stains, use water or
neutral detergent and wipe with a dry cloth.
7.1.2 To clean the interior
NOTICE
To clean the unit enclosure:
▪ Do not use any cleaning agents or chemicals.
DANGER: RISK OF ELECTROCUTION
▪ Turn OFF all power supply before removing the switch
box cover, connecting electrical wiring or touching
electrical parts.
▪ Disconnect the power supply for more than 10minutes,
and measure the voltage at the terminals of main circuit
capacitors or electrical components before servicing.
The voltage MUST be less than 50 VDC before you
can touch electrical components. For the location of the
terminals, see the wiring diagram.
▪ Do NOT touch electrical components with wet hands.
▪ Do NOT leave the unit unattended when the service
cover is removed.
CAUTION
Do NOT touch the heat exchanger fins. These fins are
sharp and could result in cutting injuries. Wear safety
gloves if you have to work on or around the heat
exchanger fins.
