•
After the installation is completed, test the air conditioner and
check if the air conditioner operates properly.
Give the user adequate instructions concerning the use and
cleaning of the indoor unit according to the Operation Manual.
Ask the user to keep this manual and the Operation Manual
together in a handy place for future reference.
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
necessary 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
deficiency.
• Be sure to use only the specified parts and accessories for
installation work.
Failure to use the specified parts may result in the air
conditioner 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
wiring 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 cer-
tain product or domain”.
• Earth the air conditioner.
Do not connect the earth wiring to gas or water piping,
lightning conductor or telephone earth wiring.
Incomplete earthing may cause electric shocks or a fire.
• Be sure to install an earth leakage breaker.
Failure to do so may cause electric shocks and a fire.
• Disconnect the power supply before touching the electric
components.
If you touch the live part, you may get an electric shocks.
• Make sure that all wiring is secure, using the specified
wirings and ensuring that external forces do not act on the
terminal connections or wirings.
Incomplete connection or fixing may cause an overheat or a
fire.
• When wiring between the indoor and outdoor units, and
wiring the power supply, form the wirings orderly so that the
control box lid can be securely fastened.
If the control box lid is not in place, overheat of the terminals,
electric shocks or a fire may be caused.
• If refrigerant gas leaks during installation work, ventilate the
area immediately.
Toxic gas may be produced if refrigerant gas comes into
contact with a fire.
• After completing the installation work, check to make sure
that there is no leakage of refrigerant gas.
Toxic gas may be produced if refrigerant gas leaks into the
room and comes into contact with a source of a fire, such as
a fan heater, stove or cooker.
• Never directly touch any accidental leaking refrigerant. This
could result in severe wounds caused by frostbite.
