< Whether or not to use R32 refrigerant leakage detection sensor >
• According to the type of diagrams shown in Fig. 2, it is necessary to install R32 refrigerant
leakage detection sensor if the installation space is within the range of using R32 refrigerant
leakage detection sensor.
• As to installation method of R32 refrigerant leakage detection sensor, refer to the
Installation Instructions attached to the indoor unit and R32 refrigerant leakage detection
sensor.
• When connecting R32 refrigerant leakage detection sensor, group connection with a remote
controller is not possible. Be sure to prepare a remote controller for each indoor unit.
The refrigerant charge amount compared with the floor area of the room is roughly as follows:
NOTE
In the case of connecting R32 refrigerant leakage detection sensor :
• For systems using R32 refrigerant, this unit is equipped with a refrigerant leak detector for
safety. To be effective, the unit must be electrically powered at all times after installation, other
than when servicing.
