Match the terminal block numbers and connection cable •
colors with those of the outdoor unit. Erroneous wiring
may cause burning of the electric parts.
Securely connect the connection cables to the terminal •
blocks. 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

Install sleeves into any holes made in the walls for wiring. •
Otherwise, a short circuit could result.
Install a ground leakage breaker. In addition, install the •
ground leakage breaker so that the entire AC main power
supply is cut off at the same time. Otherwise, electric

Always connect the ground wire. •
Improper grounding work can cause electric shocks.
Install the remote controller wires so as not to be direct •
touched with your hand.
