3-8. Wiring Instructions for Inter-unit Connections

(1)Insert the inter-unit wiring (according to local codes) into the through-the-wall PVC pipe. Run the wiring toward the indoor side allowing approx. 10" (25 cm) to extend from the wall face. (Fig. 24)

(2)Grasp both ends of the front panel, push the arms towards the outside, and remove the front panel by opening it towards the front and pulling it towards you. If the front panel is difficult to remove, grasp both ends of it and lift it up slightly. Move it to the left and disengage the left arm, then move it to the right and disengage the right arm.

(3)Remove the screw on the right side cover plate and open the cover. (Fig. 25)

(4)Route the inter-unit wiring from the back of the indoor unit and pull it toward the front for connec- tion. (Fig. 26a, 26b)

(5)Connect the inter-unit wiring to the corresponding terminals on the terminal plate (Fig. 26a, 26b) while referring to the wiring diagram.

(6)Be sure to secure the wiring with the provided clamp.

NOTE

When closing the front panel, push the central part of the front panel first and then press the bottom right and left corners in place until you feel a click. (Fig. 27)

Please refer to “How to replace the grille” on page 14 for installing the air intake grille.
