CAUTION
Pay special attention to any
location, such as a basement,
etc., where leaking refrigerant
can accumulate, since
refrigerant gas is heavier
than air.

WARNING
Always check the gas density
limit for the room in which
the unit is installed.
2-10. Check of Limit Density
When installing an air conditioner in a room, it is
necessary to ensure that even if the refrigerant gas
accidentally leaks out, its density does not exceed
the limit level for that room.
If the density could exceed the limit level, it is
necessary to provide an opening between the unit
and the adjacent room, or to install mechanical
ventilation which is interlocked with the leak detector.
(Total refrigerant charged amount: kg)
(Min. indoor volume where the indoor unit is installed: m 3 )
< Limit density 0.3 (kg/m
3
)
The limit density of refrigerant which is used in this
unit is 0.3 kg/m
3
(ISO 5149).
The shipped outdoor unit comes charged with the
amount of refrigerant fixed for each type, so add it to
the amount that is charged in the field. (For the
refrigerant charge amount at shipment, refer to the
unit’s nameplate.)
