Space requirements
2-3. Installing duct for horizontal exhaust discharge
It is necessary to install an air-discharge duct (field supply) to direct exhaust from the fan horizontally if it is difficult to provide a
minimum space of 2m(6.6 ft) between the air-discharge duct outlet and a nearby obstacle.
2-4. Installing the outdoor unit in harsh environments
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. Snow-proof duct (field supply) should be fitted to the unit and
direct exposure to the wind should be avoided as much as possible. When the unit is expected to operate in cooling mode in
condition under 10°C(50°F), in snowy areas, in environments subject to strong winds or rain, install air inlet and outlet ducting as
shown in the below example


When installing on a roof subject to strong wind, countermeasures must be taken to prevent the unit form being
overturned.

Any lack of strength may cause unit to fall down, resulting in a personal injury.
