1. SAFETY PRECAUTIONS
Be sure to follow this “SAFETY PRECAUTIONS”.
This product comes under the term “appliances not
accessible to the general public”.
This is a class A product. In a domestic environment this
product may cause radio interference in which case the user
may be required to take adequate measures.
This manual classies the precautions into WARNINGS and
CAUTIONS.
Be sure to follow all the precautions below: They are all
important for ensuring safety.
WARNING ......... Indicates a potentially hazardous
situation which, if not avoided, could
result in death or serious injury.
CAUTION .......... Indicates a potentially hazardous
situation which, if not avoided, may
result in minor or moderate injury.
It may also be used to alert against
unsafe practices.
• 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 qualied personnel to carry out
installation work.
Improper installation may result in water leakage, electric
shocks or a re.
• Perform installation work in accordance with this installation
manual.
Improper installation may result in water leakage, electric
shocks or a re.
• Consult your local 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
deciency.
• Be sure to use only the specied parts and accessories for
installation work.
Failure to use the specied parts may result in the air
conditioner falling down, water leakage, electric shocks, a
re, etc.
• Install the air conditioner on a foundation that can
withstand its mass.
It may lead to vibration of indoor units and cause
unpleasant chattering noise.
• Carry out the specied 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
qualied 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 sufcient length and never connect
additional wiring to make the length sufcient.
Insufcient capacity of the power supply circuit or improper
electrical construction may lead to electric shocks or a re.
(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,
lightning conductor or telephone earth wiring.
Incomplete earthing may cause electric shocks or a re.
• Be sure to install an earth leakage circuit breaker.
Failure to do so may cause electric shocks and a re.
• 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 specied
wiring and ensuring that external forces do not act on the
terminal connections or wiring.
Incomplete connection or xing may cause an overheat or
a re.
• When wiring between the indoor and outdoor units, and
wiring the power supply, form the wiring 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 re 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 re.
• 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 re, such
as a fan heater, stove or cooker.
• Never directly touch any accidental leaking refrigerant.
This could result in severe wounds caused by frostbite.
CAUTION
• Install drain piping according to this installation manual to
ensure good drainage, and insulate the piping to prevent
condensation.
Improper drain piping may cause water leakage, make the
furniture get wet.
