• In case of installation in cold territories (where Outdoor Temperature may fall below -5ºC) or in places where Heating load is large,
install a number of units with a connected capacity ratio under 100%.
• Please check the piping chapter for other restrictions and limitations to adequate the combinability and the number of indoor units
installed.
