Installation
(1) Install the outdoor unit in a dry well ventilated environment.
(2) Install the outdoor unit where it is in the shade or it will not be exposed to direct sunshine or direct
radiation from high temperature heat source.
(3) Install the outdoor unit where the sound or the discharge air from the outdoor unit does not affect
neighbors or surrounding ventilation. The operating sound at the rear or right/left sides is 3 to 6dB(A)
higher than the value in the catalog at the front side.
(4) Install the outdoor unit in a space with limited access to general public.
(5) Check to ensure that the foundation is flat, level and ufficiently strong
(6) Do not install the outdoor unit where dust or other contamination could block the outdoor heat
exchanger.
(7) When installing the outdoor unit in snow-covered areas, mount the field-supplied hoods on the top of
the outdoor unit and the inlet side of the heat exchanger.
(8) While heating or defrosting operation, drain water is discharged. Provide adequate drainage around
the foundation. If installing the unit on a roof or a veranda, avoid draining in or over walkways to
prevent water dripping on people or the formation of ice in winter. In case of installing such a place,
provide the additional drainage around the foundation.
(9) Do not install the outdoor unit in a space where a seasonal wind directly blows to the outdoor heat
exchanger or a wind from a building space directly blows to the outdoor fan.

gases such as sulphur and an acid or alkaline environment.
2. Do not install the outdoor unit where the electromagnetic wave is directly radiated to the electrical control
box.
3. Install the outdoor unit as far as possible, being at least 3 meters from the electromagnetic wave radiator.
