WARNING
•Electricalworkmustbeperformedinaccordancewiththis
Manualbyapersoncertiedunderthenationalorregional
regulations. Be sure to use a dedicated circuit for the unit.
An insufficient power supply circuit or improperly
performed electrical work can cause serious accidents
suchaselectricshockorre.
•Before starting work, check that power is not being
supplied to the indoor unit and outdoor unit.
•Use the included connection cables and power cables
or ones specified by the manufacturer. Improper
connections, insufficient insulation, or exceeding the
allowablecurrentcancauseelectricshockorre.
•For wiring, use the prescribed type of cables, connect
them securely, making sure that there are no external
forces of the cables applied to the terminal connections.
Improperly connected or secured cables can cause
serious accidents such as overheating the terminals,

•Do not modify the power cables, use extension cables,
or use any branches in the wiring. Improper connections,

•Matchtheterminalboardnumbersandconnectioncable
colors with those of the outdoor unit. Erroneous wiring
may cause burning of the electric parts.
•Securely connect the connection cables to the terminal
board. In addition, secure the cables with wiring holders.
Improper connections, either in the wiring or at the ends
of the wiring, can cause a malfunction, electric shock, or
