PRECAUTIONS FOR SAFETY
WARNING
WARNINGS ABOUT INSTALLATION
• Make sure to ask the qualified installation professional in electric work to install the
air conditioner.
If the air conditioner is inappropriate installed by yourself, it may cause water leak,
electric shock, fire, and so on.
• Be sure to connect ground wire. (grounding work)
Incomplete grounding cause an electric shock.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires
for telephone wires.
• If you install the indoor 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.
• Check whether the piping work has been properly completed.
When existing pipes are used and if they are not constructed properly, the refrigerant
gas may leak. Contact the installation company and confirm that the piping work has
been properly completed. For details of installation of the air conditioner, refer to the
Installation Manual. Use tools and piping materials for R410 only. Failure to do so or
improper installation may cause a burst of pipe, resulting in injury.
WARNINGS ABOUT OPERATION
• Cleaning of the air filter and other parts of the air filter involves dangerous work in high places, so be sure to have a
service person do it.
The self cleaning function of the air conditioner causes the internal fan to run at a high speed in some modes even while
the air conditioner is not working, which may cause injury.
Do not attempt it yourself.
• Avoid cooling the room too strong or exposing the human body to cool breeze for a long time as it is bad for the health.
• When you notice something abnormal with the air conditioner (smells like something scorching, poor cooling, etc.),
immediately turn off the main switch and the circuit breaker, from the mains to stop the air conditioner, and contact
the dealer.
If the air conditioner is continuously operated with something abnormal, it may cause machine failure, electric shock,
fire, and so on.
WARNINGS ABOUT MOVEMENT AND REPAIR
• When the air conditioner cannot cool or heat a room well, contact the dealer from whom you purchased the air
conditioner as refrigerant leakage is considered as the cause. In the case of repair that requires refill of refrigerant,
ask service personnel about details of the repair.
The refrigerant used in the air conditioner is harmless.
Generally, the refrigerant does not leak. However, if the refrigerant leaks in a room and a heater or stove burner in
the room catches fire, it may generate toxic gas.
When you ask service personnel for repairing refrigerant leakage, confirm that the leakage portion has been
completely repaired.
• Do not move or repair any unit by yourself.
Since there is high voltage inside the unit, you may get electric shock when removing the cover and main unit.
• Whenever the air conditioner needs repair, make sure to ask the dealer to do it.
If it is repaired imperfectly, it may cause electric shock or fire.
• When moving the air conditioner for re-installing at another place, ask the dealer to do it. If it is imperfectly installed,
it may cause electric shock or fire.
