Installation space requirements
WARNING
If appliances contain R32 refrigerant, the floor area of the room in which the
appliances are installed, operated and stored MUST be larger than the minimum
floor area defined in table below A (m

). This applies to:
▪ Indoor units without a refrigerant leakage sensor; in case of indoor units with
refrigerant leakage sensor, consult the installation manual
▪ Outdoor units installed or stored indoors (e.g. winter garden, garage, machinery
room)
NOTICE
▪ Protect pipework from physical damage.
▪ Keep the pipework installation to a minimum.
To determine the minimum floor area
