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.
• 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, the circuit breaker, from the mains to stop the air
conditioner, and contact the dealer.
