WARNING
● The installation work shall be performed by the specialist installer.
If it is not completed, it may cause a water leakage, an electric shock, a fire or falling down the unit.
● Perform the electrical work according to Installation Manual and all the relevant regulation and standards.
If the instructions are not followed, an electrical shock and fire may occur due to insufficient capacity and
inadequate performance.
● The electrical wiring work must be performed by authorized installers.
If not performing the electrical work completely or a capacity shortage of the power circuit, it may cause an
electric shock or a fire.
Additionally, if the earth wire is disconnected, it may cause an electric shock.
Contact the authorized installer and connect the earth wiring.
● If the circuit breaker or fuse is often activated, stop the system and contact your service contractor.
● Check that the ground wire is securely connected. If the unit is not correctly grounded, it will lead electric
shock. Do not connect the ground wiring to a gas piping, water piping, lighting conductor or ground wiring
for telephone.
● Use specified cables between units and choose the cables correctly. If not, an electrical shock or fire may
occur.
● Ensure that the wiring terminals are tightened securely with the specified torques. If not, generating fire or
an electrical shock at the terminal connection part may occur.
● Connect a fuse of specified capacity.
● Protect the wires, electrical parts, etc. from rats or other small animals.
If not protected, rats may gnaw at unprotected parts and which may lead to a fire.
● Fix the cables securely. External forces on the terminals could lead to a fire.
● Provide a sufficiently strong foundation. If not, the unit may fall down and it may lead to injuries.
● If the indoor unit is installed in a small room and the refrigerant gas leakage occurs, the leaked refrigerant
gas fills the room and it may cause suffocation.
Do not exceed the maximum permissible concentration of the refrigerant gas in the room.
Consult with distributor for countermeasure such a ventilation system, etc.
● Before performing any brazing work, check to ensure that there is no flammable material around.
When using the refrigerant be sure to wear leather gloves to prevent cold injuries.
● Do not install the unit in a place where oil, vapor, organic solvent and corrosive gas (ammonia, sulfur
compound and acid) may be present in quantities.
It may cause refrigerant leakage due to corrosion, electrical shock, deteriorated performance and
breakage.
● Do not insert a finger or stick into the air outlet and the air inlet.
It could cause injury due to touch the rotating fan or electrical devices.
● Do not control the wired controller by wet hand.
It may cause failure of the wired controller or an electric shock.
● Do not use any sprays such as an insecticide, lacquer, hair spray or other flammable gases within
approximately one (1) meter from the system. It may generate a fire.
● Do not install the indoor unit in a place where the air flow blows directly to heating appliances.
It may cause incomplete combustion of the heating appliances.
