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 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 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
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 fire.
A high surge current from lightning or other sources may
cause damage to the air conditioner.

•

Be sure to install an earth leakage circuit 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 wiring
and ensuring that external forces do not act on the terminal
connections or wiring.
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 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 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.

distance may be shorter in a room where an electronic light­ing type (inverter or rapid start type) fluorescent lamp is
installed.

•

Do not install the air conditioner in places such as the follow­ing:

1. Where there is mist of oil, oil spray or vapour for example
a kitchen.
Resin parts may deteriorate, and cause them to fall out or
water to leak.

2. Where corrosive gas, such as sulfurous acid gas, is pro­duced.
Corrosion of copper pipings or brazed parts may cause
the refrigerant to leak.

3. Where there is machinery which emits electromagnetic
waves.
Electromagnetic waves may disturb the control system,
and cause malfunction of the equipment.

4. Where flammable gases may leak, where carbon fibre or
ignitable dust is suspended in the air or where volatile
flammables, such as thinner or gasoline, are handled.
If the gas should leak and remained around the air condi­tioner, it may cause ignition.

•

The air conditioner is not intended for use in a potentially
explosive atmosphere.

•

Have the customer actually operate the air conditioner while
looking at the operation manual.
Instruct the customer how to operate the air conditioner (par­ticularly cleaning of the air filters, operation procedures, and
temperature adjustment).

•

For selection of installation location, use the installation pat­tern paper (used in common with the packing case.) as refer­ence.

•
