Wiring
1) As shown in the illustration, insert the wires including the ground wire into the conduit and secure them with lock nut onto
the conduit mounting plate.
2) Strip wire ends (9/16 inch (15mm)).
3) Match wire colors with terminal numbers on indoor and outdoor unit’s terminal blocks and firmly screw wires to the
corresponding terminals.
4) Connect the ground wires to the corresponding terminals.
5) Pull wires to make sure that they are securely latched up.
6) In case of connecting to an adapter system. Run the remote control cable and attach the S21.
7) Shape the wires so that the service lid fits securely, then close service lid.
WARNING
• Do not use tapped wires, stranded 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.
• When carrying out wiring connection, take care not to pull at the conduit.
• Do not connect the power wire to the indoor unit. Doing so may cause electric shock or fire.
