Note: It is possible to stop the leak detection alarm from the remote
controller and from the app. To stop the alarm from the remote
controller, press
for 3 seconds.
Note: Leak detection will trigger SVS output. For more information,

Note: An optional output PCB for the indoor unit can be added to
provide output for external device. The output PCB will trigger in
case a leak is detected. For exact model name see option list of the
indoor unit. For more information about this option, refer to the
installation manual of the optional output PCB
Note: Some centralised controllers can also be used as supervisor
remote controller. For further details on installation, please refer to
the installation manual of the centralised controllers.
NOTICE
The R32 refrigerant leakage sensor is a semiconductor
detector which may incorrectly detect substances other
than R32 refrigerant. Avoid using chemical substances
(e.g.
organic
solvents,
concentrations, in the close proximity of the indoor unit
because this may cause misdetection by the R32
refrigerant leakage sensor.

Disposal
NOTICE
Do NOT try to dismantle the system yourself: dismantling
of the system, treatment of the refrigerant, oil and other
parts MUST comply with applicable legislation. Units
MUST be treated at a specialised treatment facility for
reuse, recycling and recovery.

(A2) Then install a roof between the upper and lower
units. Install the upper unit high enough above the lower
unit to prevent ice buildup at the upper unit's bottom
plate.

(B1) If there is no danger of drainage dripping and
freezing between the upper and lower units...
(B2) Then it is not required to install a roof, but seal the
gap between the upper and lower units to prevent
discharged air from flowing back to the suction side
through the bottom of the unit.
