2-5. Minimum installation area
If you unavoidably install a unit in a space where all four sides are blocked or there are depressions, confirm that one of
these situations (A, B or C) is satisfied.
Note: These countermeasures are for keeping safety not for specification guarantee.
A) Secure sufficient installation space (minimum installation area Amin).
Install in a space with an installation area of Amin or more, corresponding to refrigerant quantity M (factory-charged
refrigerant + locally added refrigerant).

R32 is heavier than air—as well as other refrigerants—
so tends to accumulate at the base (in the vicinity of the
floor). If R32 accumulates around base, it may reach a
flammable concentration in case room is small. To avoid
ignition, maintaining a safe work environment is required
by ensuring appropriate ventilation. If a refrigerant leak is
confirmed in a room or an area where there is insufficient
ventilation, refrain from using of flames until the work
environment can be improved by ensuring appropriate
ventilation.
Install outdoor units in a place where at least one of the
four sides is open, and in a sufficiently large space with-
out depressions.
