1 General safety precautions
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
▪ 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)
▪ Pipework in unventilated spaces
To determine the minimum floor area
1 Determine the total refrigerant charge in the system (= factory
refrigerant charge +
charged).

2 Determine which graph or table to use.
▪ For indoor units: Is the unit ceiling-mounted, wall-mounted or
floor-standing?
▪ For outdoor units installed or stored indoors, and field piping
in unventilated spaces, this depends on the installation
height:
If the installation height is... Then use the graph or table for...

≥2.2 m
3 Use the graph or table to determine the minimum floor area.
