▪ Based on figure 3b, only circulation airflow is required (A

>A
min
).
▪ Based on figure 2, the minimum circulation airflow needs to
remain above 2814m³/h.
Conclusion: As long as the supplied airflow rate is above the
minimum legal requirement (2814 m³/h), no additional limitations
apply to this VRV R32 system.
12.2.3 Example 3
Installation of 8 HP R32 system:
▪ Total conditioned space area: 140m²
▪ Smallest room area: 50m²
▪ Release height (h
0
): 2.2m
▪ Total refrigerant charge: 14.4kg
▪ Indoor installation of air handling unit in a space of 20m²
Based on the smallest room area, "Figure 1"[42] indicates to follow
the requirements in figures 2 and 3.

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
refrigerant"[47]
▪ "12Special requirements for R32 units"[417]
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.
