・In abnormally harsh environments such as cold and/or windy areas, sufficient countermeasures to guard against excessive wind and snow
should be taken to ensure the unit's correct operation. When the unit is expected to operate in cooling mode in conditions under 10°C (50°F),
in snowy areas, in environments subject to strong winds or rain, install snow hoods of the following specifications (not supplied) as shown in
the figure below.
Material: Galvanized steel plate 1.2T

・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.
・When installing a panel heater, provide sufficient space for maintenance accordingly. For details, refer to the installation manual for the panel
heater.
・When installing a snow hood, take pressure loss into consideration to prevent airflow from decreasing.
