2) Match wire colours with terminal numbers on indoor and outdoor unit's terminal blocks and firmly screw wires to the
corresponding terminals.

CAUTION
When connecting the connection wires to the terminal block using a single core wire,
be sure to perform curling.
Problems with the installation may cause heat and fires.
WARNING
• Do not use tapped wires, extension cords, or starburst connections, as they may cause overheating, electrical shock, or fire.
• Do not use locally purchased electrical parts inside the product. (Do not branch the power for the drain pump, etc., from the
terminal block.) Doing so may cause electric shock or fire.
• Do not connect the indoor unit to the mains electricity. Connect it to the outdoor unit only or there may be danger of electric
