AUTION FOR REFRIGERANT LEAKS
(Points to note in connection with refrigerant leaks.)
When a unit is installed in a small room, it is necessary to
take measures so that the leaked refrigerant amount does
not exceed the limit even if it leaks. As for the measures to
prevent the leak from not exceeding the limit, please
consult with your distributor.
If the leaked amount exceeds the limit, it may cause an
oxygen deficiency accident.
Introduction
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.
The air conditioning systems, uses R410A as refrigerant. R410A
itself is an entirely safe non-toxic, non-combustible refrigerant.
Nevertheless care must be taken to ensure that air conditioning
facilities are installed in a room which is sufficiently large. This
assures that the maximum concentration level of refrigerant gas is
not exceeded, in the unlikely event of major leak in the system and
this in accordance to the local applicable regulations and standards.
