1Precautions for safety

The manufacturer shall not assume any liability for the damage

caused by not observing the description of this manual.

WARNING

General

• Carefully read Owner’s Manual before starting the air conditioner.

There are many important things to keep in mind for daily

operation.

• Ask for installation to be performed by the dealer or a

professional. Only a qualiﬁed installer(*1) is able to install an air

conditioner. If a non-qualiﬁed person installs an air conditioner, it

may result in problems such as ﬁre, electric shock, injury, water

leakage, noise and vibration.

• Do not use any refrigerant different from the one speciﬁed

for complement or replacement. Otherwise, abnormally high

pressure may be generated in the refrigeration cycle, which may

result in a failure or explosion of the product or an injury to your

body.

• Places where the operation sound of the outdoor unit may cause

a disturbance. (Especially at the boundary line with a neighbour,

install the air conditioner while considering the noise.)

• This appliance is intended to be used by expert or trained users

in shops, in light industry, or for commercial use by lay persons.

Transportation and storage

explain about the circuit breaker positions. In the event that

trouble has occurred in the air conditioner, set the circuit breaker

to the OFF position, and contact a service person.

• If the unit is installed in a small room, take appropriate measures

to prevent the refrigerant from exceeding the limit concentration

even if it leaks. Consult the dealer from whom you purchased the

air conditioner when you implement the measures. Accumulation

of highly concentrated refrigerant may cause an oxygen

deﬁciency accident.

• Do not install the air conditioner in a location that may be subject

to a risk of expire to a combustible gas. If a combustible gas

leaks and becomes concentrated around the unit, a ﬁre may

occur.

• Use the company-speciﬁed products for the separately

purchased parts. Use of non-speciﬁed products may result in

ﬁre, electric shock, water leakage or other trouble. Have the

installation performed by a professional.

voltage inside the unit, you may get electric shock when removing

the cover and main unit.

• Use of a stand more than 50 cm high to clean the ﬁlter of the

indoor unit or to carry out other such jobs constitutes working at

heights. Due to the danger of falling off the stand and injuring

yourself while working at heights, this kind of work should not be

done by unqualiﬁed individuals. When this kind of work must be

carried out, do not do it yourself but ask a qualiﬁed installer(*1) or

a qualiﬁed service person(*1) to do it for you.

• Do not touch the aluminum ﬁn of the outdoor unit. You may injure

yourself if you do so. If the ﬁn must be touched, do not touch it

yourself but contact a qualiﬁed installer(*1) or a qualiﬁed service

person(*1).
