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”.
