1 When installing RCIM-2.0FSN2, RPF(I)-2.0FSN2E or RPF(I)-2.5FSN2E, single combination with IVX Premium/Stand-
ard series not allowed.
2 In case of installation in cold territories (where Outdoor Temperature may fall below -10ºC for Utopia IVX Premium and
-5ºC for Utopia IVX Standard) or in places where Heating load is large, install a number of units not bigger than sug-
gested number of connected units, with a connected capacity ratio under 100%.
3 Please check the piping chapter for other restrictions and limitations to adequate the combinability and the number of
indoor units installed.
4 See “Piping work and refrigerant charge” for detailed information and additional remarks about combinability.
