Installing the outdoor unit in cold region
In cold regions with lots of snowfall, install a snow prevention duct, as a sufficient countermeasure, to prevent snow from
accumulating on the outdoor unit. When the snow prevention duct is not installed, frost may accumulate on the heat
exchanger and operation may not work normally.
Air outlet of the duct should not be directed to the enclosed space.
