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
2
). 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)
▪ Pipework in unventilated spaces
To determine the minimum floor area
1
Determine the total refrigerant charge in the system (= factory
refrigerant charge
+
additional refrigerant amount
charged).
Contains fluorinated greenhouse gases

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…
