2. Check of limit density
When installing an air conditioner in a room, it is
necessary to ensure that even if the refrigerant gas
accidentally escapes, its density does not exceed the
limit level.
If the density might exceed the limit level, it is
necessary to set up an opening between it and the
adjacent room, or to install mechanical ventilation
which is interlocked with a leak detector.
(Total refrigerant charged amount: k
g
)
(Min. indoor volume where the indoor unit is installed: m³)
< Limit density 0.3 (k
g
/m
3
)
The limit density of refrigerant which is used in this
unit is 0.3 k
g
/m
3
(ISO 5149).
The shipped outdoor unit comes charged with the
amount of refrigerant fi xed for each type, so add it
to the amount that is charged at the fi eld. (For the
refrigerant charge amount at shipment, refer to the
unit’s nameplate.)
Minimum indoor volume & fl oor area relative to the
amount of refrigerant are roughly as given in the
following table.
Pay special attention to any
location, such as a basement
or recessed area, etc. where
leaked refrigerant can
collect, since refrigerant gas
is heavier than air.
