Only a qualified installer or service person is allowed to do installation work. Inappropriate installation
may result in water leakage, electric shock or fire.
Before starting to install the air conditioner, read carefully through the Installation Manual, and follow its
instructions to install the air conditioner.
Be sure to 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 failure. Have the installation
performed by a qualified installer.
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.
Install the indoor unit at least 2.5 m above the floor level since otherwise the users may injure
themselves or receive electric shocks if they poke their fingers or other objects into the indoor unit
while the air conditioner is running.
Installation
Install a circuit breaker that meets the specifications in the installation manual and the stipulations in
the local regulations and laws.
Install the circuit breaker where it can be easily accessed by the agent.
If you install the unit 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 place any combustion appliance in a place where it is directly exposed to the wind of air
conditioner, otherwise it may cause imperfect combustion.
Explanations given to user
If you have discovered that the fan grille is damaged, do not approach the outdoor unit but set the circuit
breaker to the OFF position, and contact a qualified service person to have the repairs done.
Do not set the circuit breaker to the ON position until the repairs are completed.
Relocation
• Only a qualified installer (*1) or qualified service person (*1) is allowed to relocate the air conditioner.
It is dangerous for the air conditioner to be relocated by an unqualified individual since a fire, electric shocks,
injury, water leakage, noise and / or vibration may result.
• When carrying out the pump-down work shut down the compressor before disconnecting the refrigerant pipe.
Disconnecting the refrigerant pipe with the service valve left open and the compressor still operating will
cause air, etc. to be sucked in, raising the pressure inside the refrigeration cycle to an abnormally high level,
and possibly resulting in reputing, injury, etc.
