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 prod-
uct may cause radio interference in which case the user may be 
required to take adequate measures.

This manual classifies the precautions into WARNINGS and 
CAUTIONS.
Be sure to follow all the precautions below: They are all impor-
tant for ensuring safety.

WARNING

 ............. Indicates a potentially hazardous situ-

ation which, if not avoided, could result 
in death or serious injury.

CAUTION

 .............. Indicates a potentially hazardous situ-

ation 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 qualified personnel to carry out installa-

tion 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 local 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 installa-
tion 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”.

• 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 the remote controller wiring and transmission 

wiring, and wiring the power supply, form the wiring orderly 
so that the control box cover can be securely fastened.
If the control box cover is not in place, overheat of the termi-
nals, 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 con-
tact 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.

• Disconnect the power supply before touching the electric 

components.
If you touch the live part, you may get an electric shocks.

• 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.
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.

CAUTION

• Install drain piping according to this installation manual to 

ensure good drainage, and insulate the piping to prevent 
condensation.
