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
inlets and air outlet
• 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 sulfide 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
• 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.

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 windproofing
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.
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.
• 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.
