Installation location

 WARNING

Install the outdoor unit properly in a location that is
durable enough to support the weight of the outdoor
unit.

Insufficient durability may cause the outdoor unit to fall,
which may result in injury.

 CAUTION

Do not install the outdoor unit in a location that is
subject to combustible gas leaks.

Accumulation of combustible gas around the outdoor
unit may cause a fire.

Install the outdoor unit in a location that meets the
following conditions after the customer’s consent
is obtained.

•  A well-ventilated location free from obstacles near

the air intakes and air discharge.

•  A location that is not exposed to rain or direct

sunlight.

•  A location that does not increase the operating noise

or vibration of the outdoor unit.

•  A location that does not produce any drainage

problems from discharged water.

Do not install the outdoor unit in the following
locations.

•  A location with a saline atmosphere (coastal area) or

one that is full of sul

fi

 de gas (hot-spring area)

(Special maintenance is required).

•  A location subject to oil, vapor, oily smoke, or 

corrosive gases.

•  A location in which organic solvent is used.
•  Places where iron or other metal dust is present. If

iron or other metal dust adheres to or collects on the
interior of the air conditioner, it may spontaneously
combust and start a 

fi

 re.

•  A location where high-frequency equipment

(including inverter equipment, private power
generator, medical equipment, and communication
equipment) is used (Installation in such a location
may cause malfunction of the air conditioner,
abnormal control or problems due to noise from such
equipment).

•  A location in which the discharged air of the outdoor

unit blows against the window of a neighboring
house.

•  A location where the operating noise of the outdoor

unit is transmitted.

•  When the outdoor unit is installed in an elevated 

position, be sure to secure its feet.

•  A location in which drain water poses any problems.

 CAUTION

1

   Install the outdoor unit in a location where 

the discharge air is not blocked.

2

  When an outdoor unit is installed in a 

location that is always exposed to strong 
winds like a coast or on the high stories of a 
building, secure normal fan operation by
using a duct or wind shield.

3

   When installing the outdoor unit in a

location that is constantly exposed to strong
winds such as on the upper stairs or rooftop
of a building, apply the windproo

fi

ng

measures referred to in the following
examples.

1)  Install the unit so that its discharge port faces

the wall of the building.
Keep a distance 500 mm or more between the
unit and wall surface.

500 mm

2)  Consider the wind direction during the

operational season of the air conditioner, and
install the unit so that the discharge port is set
at a right angle relative to the wind direction.

Strong wind

Strong wind

•  When using an air conditioner under low outside

temperature conditions (Outside temp: -5 °C or lower)
in COOL mode, prepare a duct or wind shield so that
it is not affected by the wind.
