¡
Do not place the power supply cords above the gutter, because the air
conditioner is structured in a way where condensation on the back side is
collected in to the drain pan before drainage.
Use cables for interconnection wiring to avoid loosening of the wires.

1) Connect the connection wire securely to the terminal block. If the wire is not affixed completely, contact will be
poor, and it is dangerous as the terminal block may heat up and catch fire.
2) Take care not to confuse the terminal numbers for indoor and outdoor connections.
3) Affix the connection wire using the wiring clamp.
d) Attach the terminal block cover.
e) Attach the lid.
4) Shaping the pipe and drain hose
