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.

(*1) Refer to the “Definition of Qualified Installer or Qualified Service Person”

position, and then wait at least 10 minutes before opening the service panel.
If you fail to heed this warning, you will run the risk of burning yourself because the compressor pipes and other
parts will be very hot to the touch. In addition, before proceeding with the repair work, wear the kind of insulated
heat-resistant gloves designed to protect electricians.

Installation

Only a qualified installer (*1) or qualified service person (*1) is allowed to install the air conditioner. If the air
conditioner is installed by an unqualified individual, a fire, electric shocks, injury, water leakage, noise and/or
vibration may result.

Before starting to install the air conditioner, read carefully through the Installation Manual, and follow its
instructions to install the air conditioner.

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 2.0 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.

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 qualified service person (*1).

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 place any combustion appliance in a place where it is directly exposed to the wind of air conditioner,
otherwise it may cause imperfect combustion.
