・Install the unit so that the wind will not blow directly against the inlet and outlet.
・If necessary, install the unit on a raised base of the following specifications (not supplied) to prevent damage
from snow.
Material: Angle iron (Build a structure that snow and wind can pass through.)
Height: Expected maximum snowfall plus 200 mm (7-7/8 in)
Width: Within the unit width (If the raised base is too wide, snow will accumulate on the raised base.)
・When the unit is used in a cold region and the heating operation is continuously performed for a long time when
the outside air temperature is below freezing, install a heater on the raised base or take other appropriate
measures to prevent water from freezing on the raised base.
