32Installation procedure Electric wiringWiring connection method : (the wiring diagram is attached inside the machine)1) Ring terminal connection methodIf there is a ring at the end of the connection wire,the wire connection method is as shown in the rightfigure. Remove the terminal screw and insert itthrough the ring at the connection wire end, thenconnect to the terminal board and fasten the screw.2) Straight terminal connection methodIf there isnt a ring at the end of the connection wire,the connection method shall be: loosen the terminalscrew, insert the connection wire end completelyinto the terminal board and fasten the screw. Pull theconnection wire outwards slightly to confirm it isclamped tightly.3) Clamping method of the connection wireAfter wire connection is finished, the connection wiremust be pressed tightly with wire clips, which shallapply to the outer sheath of the connection wire.Wire connection for built-in indoor unitl Insert from outside the connection wire and signal transmission wire through the wall holewith pipeline already arranged.l Pull out the front ends of connection wire and signal wire and make a circle on the signalwire.l Connect the connection wire according to the connection method and indoor and outdoorwiring diagram.l Pull the connecting conductor outwards slightly to confirm it is clamped tightly.l Connect the plug for connecting the signal wire with the plug of the signal wire connectedfrom the indoor unit.l After wire connection is finished, install wire clips using the same method for connectionwire clamping.Note: When connecting the indoor unit and the outdoor unit, please do connect the wireswith the same color terminals.Notes:l Before connecting the conductors between indoor unit and outdoor unit, check for the nu-mber on the indoor and outdoor units connecting terminals. Connect the terminals with thesame color and number with a wire.l Wrong connection would damage the controller of the air conditioner or the machine cou-ldnt operate.l Do not connect the connection wire and signal wire with the same cable. They shall be co-nnected respectively to ensure system normal operation.Connection methodfor ring terminal
