12. CHECK OF DENSITY LIMIT
The refrigerant (R32), which is used in the air conditioner, is a flammable refrigerant. So the
requirements for installation space in each room of appliance are determined according to the
refrigerant charge amount [m
c
] used in the appliance.
Regarding the refrigerant charge amount [m
c
] used in the appliance, refer to the installation
instructions for the outdoor unit.
The minimum indoor floor space compared with the amount of refrigerant is roughly as follows:
0.0
