REFRIGERANT LEAKAGE CAUTION11.
The installer and system specialist shall secure safety against leakage according to local
regulations or standards. The following standards may be applicable if local regulations are not
available.
INTRODUCTION11-1.
This air conditioners use R410A as refrigerant. Though R410A is harmless and incombustible
in itself, the room in which the air conditioner is installed should be large enough that the
refrigerant gas will not exceed the concentration limit even if the refrigerant gas leaks.
Concentration limit

Concentration limit is the limit of Freon gas concentration where immediate measures can be
taken without hurting the human body when refrigerant leaks in to the air.
The concentration limit shall be described in units of kg/m
3
(Freon gas weight in per m
3
air) to
facilitate calculation.
Concentration limit : 0.3kg/m
