INFORMATION
An air curtain is a heating-only product designed primarily
for providing air separation. Therefore, it cannot be
considered a comfort product.
13 Special requirements for R32
units
13.1 Requirements for compatible air
curtains
INFORMATION
In this section, the term "indoor unit" is used for air curtain
applications.
13.1.1 Installation space requirements
WARNING
If the appliance contains R32 refrigerant, the floor area of
the room in which the appliance is stored shall be at least
429m².
NOTICE
▪ The pipework shall be securely mounted and guarded
protected from physical damage.
▪ Keep the pipework installation to a minimum.
13.1.2 System layout requirements
The ERA uses R32 refrigerant which is rated as A2L and is mildly
flammable.
To comply with the requirements of enhanced tightness refrigerating
systems of the IEC 60335-2-40, this system is equipped with an
alarm in the remote controller and natural ventilation can be used as
a safety measure. Both safety measures are installation specific and
can be determined using the requirements mentioned in this manual.
In case the requirements of this manual are followed, no additional
safety measures are needed.
A big range of charge and room area combinations is allowed thanks
to the countermeasures that are implemented in the system by
default.
Follow the installation requirements below to ensure that the
complete system is compliant to legislation.
Outdoor unit installation
The outdoor unit must be installed outside. For indoor installation of
the outdoor unit, additional measures can be necessary to comply
with the applicable legislation.
A terminal for external output is available in the outdoor unit. This
SVS output can be used when additional countermeasures are
needed. The SVS output is a contact on terminal X2M that closes in
case a leak is detected, failure or disconnection of an R32 sensor
(located in the air curtain).
For more information about the SVS output, see "17.5 To connect
the external outputs"[435].
Indoor unit installation
For installation of the compatible air curtain, refer to the installation
and operation manual delivered with the air curtain. For compatibility
of air curtain refer to the latest version of the technical data book of
this outdoor unit.
Depending on the room size in which the air curtain is installed and
the total amount of refrigerant in the system, other safety measures
are necessary for these indoor units. See "13.1.3To determine the
required safety measures"[418].
An optional output, if available on a compatible air curtain, can be
used for an external device. The output will trigger in case a leak is
detected, the R32 sensor fails or when the sensor is disconnected.
For more information about this output, refer to the installation
manual of the compatible air curtain unit.
