WARNING
• Ask your local dealer or qualified personnel to carry out
installation work.
Improper installation may result in water leakage, electric
shocks or a fire.
• Perform installation work in accordance with this installation
manual.
Improper installation may result in water leakage, electric
shocks or a fire.Consult your dealer regarding what to do in
case of refrigerant leakage.
When the air conditioner is installed in a small room, it is nec-
essary to take proper measures so that the amount of any
leaked refrigerant does not exceed the concentration limit in
the event of a leakage.
Otherwise, this may lead to an accident due to oxygen defi-
ciency.
• Be sure to use only the specified parts and accessories for
installation work.
Failure to use the specified parts may result in the air condi-
tioner falling down, water leakage, electric shocks, a fire, etc.
• Install the air conditioner on a foundation that can withstand
its mass.
Insufficient strength may result in the air conditioner falling
down and causing injury.
In addition, it may lead to vibration of indoor units and cause
unpleasant chattering noise.
• Carry out the specified installation work in consideration of
strong winds, typhoons, or earthquakes.
Improper installation may result in an accident such as air
conditioner falling.
• Make certain that all electrical work is carried out by qualified
personnel according to the applicable legislation (note 1) and
this installation manual, using a separate circuit.
In addition, even if the wiring is short, make sure to use a wir-
ing that has sufficient length and never connect additional
wiring to make the length sufficient.
Insufficient capacity of the power supply circuit or improper
electrical construction may lead to electric shocks or a fire.
(note 1) applicable legislation means “All international,
national and local directives, laws, regulations and/
or codes which are relevant and applicable for a
certain product or domain”.
• Earth the air conditioner.
Do not connect the earth wiring to gas or water piping, light-
ning conductor or telephone earth wiring.
Incomplete earthing may cause electric shocks or a fire.

Incomplete connection or fixing may cause an overheat or a
fire.
• When wiring between the indoor and outdoor units, and wir-
ing the power supply, form the wirings orderly so that the con-
trol box cover can be securely fastened.
If the control box cover is not in place, overheat of the termi-
