Initial Check
• Install the outdoor unit where good ventilation is
available, and where it is dry.
• Install the outdoor unit where the sound or the
discharge air from the outdoor unit does not
affect neighbors or surrounding vegetation.
The operating sound at the rear or right/left
sides is higher than the value in the catalog at
the front side.
• Check to ensure that the foundation is flat, level
and sufficiently strong.
• Do not install the outdoor unit where there is a
high level of oil mist, salty air or harmful gases
such as sulphur.
• Do not install the outdoor unit where the
electromagnetic wave is directly radiated to the
electrical box.
• Install the outdoor unit as far as practical, being
at least 3 meters from the electromagnetic
wave radiator.
• When installing the outdoor unit in snow-
covered areas, mount the field-supplied hoods
at the discharge side of the outdoor unit and
the inlet side of the heat exchanger.
• 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.
• Do not install the outdoor unit where dust or
other contamination could block the outdoor
heat exchanger.
• Install the outdoor unit in a space with limited
access to general public.
• 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.

• In case of installation in the open spaces
unavoidably where there is no buildings or
surrounding structures, adopt the wind guard
set or install near the wall to avoid facing the
wind directly. Ensure that the service space
should be secured.

Secure the adequate
service space(600mm).
NOTE:
If the extreme strong wind blows directly against
the air discharge portion, the fan may rotate
reversely and be damaged.
Aluminum fins have very sharp edges. Pay
attention to the fins to avoid any injury.
Install the outdoor unit on a roof or in an area
where people except service engineers can not
touch the outdoor unit.
