▪ Based on figure 3b, only circulation airflow is required (A
tot
>A
min
).
▪ Based on figure 2, the minimum circulation airflow needs to
remain above 2814m³/h.
▪ Based on figure 3a, additional ventilation in the installation
location is required (A

).
Note: Figure 3a is only applicable if the air handling unit is
installed indoors.
Calculation of the minimum additional ventilation airflow rate
(Q

If mechanical extraction is required, the mechanical extraction must
take place to the outdoor or indoor space when the room area is
larger than the minimum room area (EAmin), using the calculation

13 Unit installation
WARNING
In case of R32 refrigerant, the installation MUST comply
with the requirements that apply to this R32 equipment.
For more information, see:
▪ "2.1 Instructions for equipment using R32

For the control box and the expansion valve kit:
▪ The unit can be installed indoors and outdoors, but do NOT install
it in direct sunlight. Direct sunlight will increase the temperature
inside the unit and may reduce its lifetime and influence its
operation.
▪ Choose a flat and strong mounting surface.
▪ The operating temperature of the unit is between –20°C and 52°C.
▪ Do NOT install the unit in or on the outdoor unit.
▪ Do NOT install or operate the unit in rooms:
▪ Where mineral oil, like cutting oil is present.
▪ Where the air contains high levels of salt, e.g. air near the
ocean.
▪ Where sulphurous gas is present, e.g. in areas of hot springs.
▪ In vehicles or vessels.
▪ Where voltage fluctuates a lot, e.g. in factories.
▪ Where high concentration of vapor or spray are present.
▪ Where machines generating electromagnetic waves are
present.
▪ Where acidic or alkaline vapor is present.
