B. 18000 BTU and 24000 BTU inverter models

(1)Remove the air intake grille.

(2)Remove the terminal cover. Pull out the thermistor, then remove the grille.

•For details on steps (1) and (2), refer to the Installation Instructions included in the outdoor unit package.

(3)Disengage the top cover from the tabs on the sides of the component box, then pull the cover toward you to remove it. (Fig. 1)

(To disengage the tabs, pull the sides of the top cover sideways and outward from the component box.)

(4)Disconnect the indicator-side connector (10P) of the wires that connect the indi- cator and component box (Fig. 2a). Then disconnect the connector on the com- ponent box side (10P) and remove the wires. (Lifting the P.C. board up slightly will make this work easier.) (Fig. 2b)

(5)After removing the wires, insert Connector 1 of the wires (Fig. 3a) that were included in the kit package into the indicator (Fig. 2a), then insert Connector 2 into the component box. (Fig. 2b)

At this time, pass the wires through so that they are held inside the 2 holders on the sides of the component box. (Fig. 3b)

(6)Feed the wire harness that was included in the wired remote controller package into the right lower rear of the unit. (Fig. 4a)

•Be careful not to damage the wire harness when installing the conduit during unit installation work.

(7)Pass the wire harness through the wire tube that was included in the kit package. Then connect Connector 3 (Fig. 3a) to the wire harness connector (4P). (Fig. 4c)

(8)Take the wires (Fig. 3a) and use a wire clamp to bind together the wire for the noise filter and the wire for the thermistor (Fig. 5a). Then position them so that the noise filter is contained within the space of the component box. (Fig. 5b)

(9)Pass the wire tube through the clamping strap, and temporarily fasten in place with the screw. Next, use a clamp and bind the wires together immediately above the clamping strap, and fasten in place with the screw in order to prevent pulling on the wire harness. (Fig. 6a)

•Install the wire tube so that the wires cannot be damaged by the edge of the metal plate. (Fig. 6a)

•When re-installing the grille, confirm that there is no slack in the wire harness wires.

(10)Install the top cover on the component box. (Fig. 8)

(11)Route the wire harness out through the small cut-out located at the bottom right side of the indoor unit frame. (Fig. 7a)

(12)Apply the label that was included in the package at a location close to the self- diagnostic label applied to the air intake grille. (Fig. 7b)

(13)Refer to the Installation Instructions that were included in the outdoor unit pack- age and re-install the grille, thermistor, terminal cover, and air intake grille.
